But the market is changing.

More homeowners are asking for slimmer frames, larger openings, modern finishes and a more premium look.

Installers are being asked to provide products that feel contemporary, perform well and suit everything from extensions and renovations to garden rooms and new builds.

That is why Nova has now launched a new range of aluminium windows and doors for trade installers, manufactured using premium Sheerline aluminium profiles.

This new aluminium range gives our trade customers more choice, more flexibility and more ways to meet demand from homeowners who want something beyond standard uPVC

Why Aluminium Windows And Doors Are Becoming More Popular

uPVC is still a practical, cost-effective and reliable option for many homeowners. It performs well, is easy to maintain and remains one of the most popular choices in the UK.

However, aluminium offers a different type of finish.

For projects where appearance, scale and premium styling matter, aluminium has become increasingly popular. It gives homeowners the slim, modern look they often see in magazines, extensions, garden rooms and higher-end properties.

One of the biggest differences is the frame profile. Aluminium is naturally strong, which means the frames can be slimmer than traditional uPVC alternatives.

Slimmer sightlines mean more glass, more natural light and a cleaner overall appearance.

This is especially useful for larger openings, where homeowners want to connect living spaces with gardens, patios or outdoor areas.

For installers, this creates an opportunity.

Aluminium allows you to offer a more premium option to customers who want modern design, strong performance and a high-quality finish.

What Is Included in Nova’s New Aluminium Range?

Nova’s new aluminium range has been introduced to give trade installers a complete choice of modern window and door options.

The range includes:

Aluminium bi-fold doors, ideal for wide openings and open plan living spaces.

Lift and slide aluminium patio doors, designed for large glazed areas with smooth operation and a premium feel.

Inline aluminium patio doors are a practical sliding door option for homeowners who want space-saving access to gardens and patios.

Aluminium casement windows are a modern alternative to traditional window styles with slim frames and strong performance.

Aluminium flush casement windows, ideal for projects where a cleaner, more refined external finish is needed.

Aluminium casement doors, suitable for matching door and window projects where consistency matters.

This gives installers a more complete aluminium offering, without needing to source products from multiple suppliers.

Why Nova Has Chosen Sheerline Aluminium Profiles

Nova’s new aluminium range is manufactured using Sheerline aluminium profiles, a premium system designed to deliver the modern look homeowners want while also supporting the practical needs of trade installers.

Sheerline is known for its slim sightlines, strong thermal performance and high-quality finish.

This makes it a strong choice for installers who want to offer a more premium aluminium product alongside uPVC.

It has also been developed with installer-friendly features that help make fabrication and installation more straightforward.

For example, the system uses pre-gasketed clip-in beads, helping to remove the need for wedge gaskets or milled beads. This can help reduce complexity, improve consistency and save time during the manufacturing and fitting process.

Another important benefit is the ability to create internally beaded fixed lights using the reverse butt joint.

Internally beaded windows are widely preferred because they provide a cleaner appearance and offer additional security reassurance for homeowners.

For installers, this means a neater, more practical solution without relying on external glazing methods, reverse adaptors or dummy sashes.

For homeowners, it means a more consistent finish, a modern appearance and added confidence in the product.

In short, Sheerline gives Nova’s trade customers a premium aluminium system that looks good, performs well and has been designed with both the installer and end user in mind.

Aluminium vs uPVC: When Does Aluminium Make Sense?

This is not about saying aluminium is better than uPVC in every situation. Both have their place.

uPVC is still a great choice for many everyday projects. It is cost-effective, reliable, energy-efficient and low maintenance. For standard replacement windows, rental properties and budget-conscious projects, uPVC remains a strong option.

Aluminium makes sense when the customer wants something more premium.

It is particularly suited to:

• Modern extensions
• Large patio openings
• Garden rooms
• New build properties
• Higher value renovations
• Contemporary homes
• Projects where slim sightlines are important

The key benefit is appearance. Aluminium gives a sharper, more architectural look. The frames are slimmer, the glass areas can be larger and the overall finish feels more modern.

For trade installers, this means you can offer customers a choice. If they want practical and cost-effective, uPVC is there. If they want premium, modern and design-led, aluminium gives you another option.

Key Benefits of Aluminium Windows and Doors

Aluminium offers several benefits that make it attractive to both installers and homeowners.

Slim Sightlines

One of the biggest selling points of aluminium is the slim frame design. Because aluminium is strong, the frames do not need to be as bulky as some other materials.

For homeowners, this means more glass and less frame. Rooms feel brighter, views feel clearer and the overall finish looks more modern.

For installers, it gives you a strong selling point when speaking to customers who are focused on appearance.

Ideal for Larger Openings

Aluminium is well-suited to larger door sets and wide glazed areas. This makes it a strong choice for bi-fold doors, sliding patio doors and open plan extensions.

Homeowners increasingly want large openings that connect indoor and outdoor spaces. Aluminium helps make that possible while still offering strength, durability and smooth operation.

Strong and Durable

Aluminium is a robust material that is built to last. It does not warp or swell and is designed to perform well in everyday UK weather conditions.

This gives homeowners confidence in the long-term performance of the product, while helping installers reduce the risk of future issues.

Smooth Operation

Modern aluminium doors are designed to operate smoothly, even on larger systems. This is especially important for sliding doors and bi-folds, where the customer experience depends heavily on how easy the product is to use.

A door that looks good but feels awkward to operate will quickly cause frustration. Aluminium systems are built to provide a premium feel as well as a premium look.

Modern Aesthetics

Aluminium has a clean, sharp appearance that works well on contemporary homes, extensions and garden rooms.

It is also popular with homeowners who want darker frame colours, such as grey or black, because these finishes tend to suit the modern aluminium look particularly well.

The Sheerline system also supports a more consistent appearance across the installation. This is particularly useful on projects where fixed lights, openers and doors all need to look visually balanced.

Strong Thermal Performance

Older aluminium products had a reputation for being less thermally efficient, but modern aluminium windows and doors have moved on significantly.

Today’s aluminium products use advanced thermal technology to help reduce heat loss and improve energy performance. This means installers can offer aluminium while still meeting the expectations of modern homeowners around comfort and efficiency.

Why This Matters for Trade Installers

The launch of Nova’s aluminium range is not just about adding more products. It is about helping trade installers respond to what customers are asking for.

Homeowners are more design aware than ever. Many are researching styles online before they ever speak to an installer. They know they want slim frames, wide openings and a premium finish.

If you can offer aluminium alongside uPVC, you are in a stronger position.

It allows you to quote for a wider range of projects, offer better choices and potentially win higher value work. You are not limited to one type of product or one type of customer.

It also helps you present yourself as a more complete installer. Rather than saying “we only offer uPVC”, you can guide customers through their options and recommend the right product for the job.

That kind of advice builds trust.

Why Nova Has Introduced Aluminium

Nova has always focused on supporting the trade with reliable products, honest advice and straightforward service.

The aluminium range is the next step in that journey.

We are not moving away from uPVC. We are expanding our offering so our trade customers have more options when quoting and winning work.

Many installers already trust Nova for their uPVC windows and doors. By adding aluminium, we can help those same installers take on a wider range of projects without having to build a relationship with a completely new supplier.

“We’ve always been known for supporting trade installers with reliable uPVC products, but the market is changing. More customers are asking for aluminium because they want slimmer frames, larger openings and a more modern finish. By choosing Sheerline, we can offer installers a premium aluminium system that looks great, performs well and is designed with the trade in mind.”

Scott, Director at Nova Trade Frames

That means familiar service, familiar support and a wider product range.

The Benefit of Working With Nova

When you work with Nova, you are not just ordering a product. You are working with a supplier that understands the trade.

We know that timing matters. We know that communication matters. We know that when something arrives wrong or late, it reflects on you as the installer.

That is why our approach stays the same across both uPVC and aluminium.

You can expect made-to-measure products, practical support, clear communication and a team that understands what installers need to keep projects moving.

The new aluminium range gives trade customers another option, while keeping the same Nova service they already know.

Why Trade Installers Should Apply for a Trade Account

If you are not already set up with Nova, applying for a trade account is a simple way to access our full product range and support.

A trade account gives you a more direct relationship with the team, making it easier to request quotes, discuss upcoming projects and get advice when you need it.

It also means you can start offering both uPVC and aluminium options to your customers, giving you more flexibility when quoting for different types of work.

Whether you are a sole installer, builder, developer or growing installation business, having the right supplier behind you can make a real difference.

Final Thoughts

The launch of Nova’s aluminium windows and doors range is an important step forward.

uPVC remains a strong and reliable choice for many projects, but aluminium gives trade installers another option for customers who want something more modern, premium and design led.

With slim sightlines, strong durability, smooth operation, advanced thermal performance and installer-friendly Sheerline profiles, aluminium is becoming an increasingly important part of the window and door market.

For installers, this is an opportunity to expand what you offer, win different types of projects and give customers more choice.

Nova is here to support that.

If you would like to find out more about the new aluminium range, request a quote or open a trade account, get in touch with the team today.

That is why more installers are now looking for a window supplier for installers that offers more than just products.

At Nova Trade Frames, we have always taken that approach. Supporting our customers has been part of how we work from day one. Now, we are taking that one step further with the introduction of our Trade Partner Scheme.

Whether you mainly install uPVC, aluminium, or a mix of both, the aim is the same: to give you reliable products, practical support and a supplier relationship that helps you move forward.

Why Installers Need More Than Just a Supplier

Being an installer today is not just about fitting windows and doors. You are running a business, managing jobs, and dealing with customers who expect a high standard from start to finish.

We regularly speak to installers who are:

• Unsure how to price certain jobs competitively
• Dealing with unusual or complex installations
• Losing time chasing answers from suppliers
• Trying to grow but not sure what the next step looks like

A standard supplier does not help with any of this. They supply the product and leave you to figure the rest out.

That is where having the right support makes a real difference.

“We have worked with installers at every stage, from one-man bands to established teams. The challenges are always similar, it is just the scale that changes.”
— Scott, Director at Nova Trade Frames

What a Good Window Supplier for Installers Should Offer

A good window supplier for installers should make your life easier, not more complicated.

That means:

• Clear, honest communication
• Reliable lead times you can plan around
• Products that are made to measure and ready to fit
• Support when you need advice or help

But more importantly, it means having a supplier that understands how your business works.

You should not feel like you are chasing updates or guessing your way through a job. You should feel confident that your supplier has your back.

Introducing the Nova Trade Partner Scheme

At Nova, we have always supported our trade customers beyond simply supplying products. Whether that is helping with specifications, offering advice, or solving problems quickly, it has always been part of our service.

The Trade Partner Scheme is not a complete change in direction. It is a way of formalising what we already do and making it clearer to our customers.

It is built around one simple idea. If our customers grow, we grow with them.

What This Means for Installers

Becoming part of the Trade Partner Scheme gives you access to support that goes beyond the standard supplier relationship.

This includes:

• Direct technical support from experienced people who understand the job
• On-site engineer support when you need help with surveys, troubleshooting, or installation
• Help with quotes and pricing so you can go back to your customer with confidence
• Practical guidance on installation and manufacturing to help you get it right first time
• Ongoing business support to help you grow
• Leads and referrals where possible
• Consistent, UK manufactured products with reliable lead times
• Manufacturer-backed warranties for added peace of mind

All of this is designed to make your day-to-day work easier and help you build a stronger business.

Real World Support That Makes a Difference

This kind of support is not just a list of features. It has a real impact on how jobs run.

We have worked with installers who were unsure how to price larger jobs. With a bit of guidance, they were able to put together more competitive quotes and win work they might have previously missed.

In other cases, our team has been out on site helping solve installation challenges, saving time and avoiding delays.

For newer installers, having someone to speak to and sense-check decisions can make a big difference in building confidence.

“Sometimes it is not about the product, it is about giving someone the confidence to move forward with a job. A quick conversation can make all the difference.”
— Scott, Director at Nova Trade Frames

Why Installers Choose Nova

There are a lot of suppliers in the market, but what makes the difference is how they work with their customers.

At Nova, we keep things straightforward.

• You deal directly with us, not a call centre
• Problems are dealt with quickly and properly
• We bring over 40 years of industry experience
• We focus on long-term relationships, not short-term transactions

It is not about overcomplicating things. It is about doing a good job, being reliable, and supporting the people we work with.

Built Around Helping You Grow

One of the biggest things we take pride in is seeing our customers grow.

We have worked with installers who started out on their own and have gone on to build strong, established businesses. That growth comes from a combination of hard work, good products, and the right support behind the scenes.

By offering consistent quality, honest advice, and ongoing support, we help you take the next step, whatever that looks like for your business.

Final Thoughts

Choosing the right window supplier for installers is about more than just getting products delivered. It is about finding a company that understands your challenges and supports your goals.

The Trade Partner Scheme is simply an extension of what Nova has always done. Supporting installers, solving problems, and helping businesses move forward.

If your current supplier is just supplying, it might be time to expect more.

Ready to Work with a Supplier That Supports You?

If you are looking for more than just a supplier and want a company that is genuinely behind you, we would love to hear from you.

You can apply for a trade account, request a quote, or learn more about the Nova Trade Partner Scheme to see how we can support your next project.

Even experienced installers can get caught out. It only takes a small mistake to turn into a bigger problem on site. That is why understanding how to properly measure uPVC windows is so important.

In this guide, we will walk through the process step by step, highlight common mistakes, and show you how to avoid them.

Why Accurate Measurements Matter

Accurate measurements are the foundation of a successful install. When windows are made to measure, they are built exactly to the sizes you provide. There is very little room for error.

If a frame is too large, it simply will not fit without making adjustments to the opening. If it is too small, you are left trying to fill gaps, which can affect both the finish and performance.

We have worked with installers who have had to delay jobs because of a simple measuring error. In one case, a window was ordered just slightly too wide, which meant removing additional brickwork before it could be fitted. That added time, cost, and frustration to what should have been a straightforward job.

“Most issues we see with supply only orders come back to measurements. It is always worth double checking before placing the order.”
— Scott, Director at Nova Trade Frames

What You Need Before You Start

Before you begin measuring, make sure you have everything you need:

• A reliable tape measure or laser measure
• Access to both the inside and outside of the opening
• Something to record your measurements
• A clear understanding of whether you are measuring the aperture or the final frame size

Taking a few minutes to prepare properly will help avoid mistakes later.

Step by Step Guide to Measuring uPVC Windows

Measuring correctly is not complicated, but it does require consistency and attention to detail.

Measure the Width

Start by measuring the width of the opening in three places:

• At the top
• In the middle
• At the bottom

Openings are not always perfectly straight, especially in older properties. Using three measurements helps you identify any variation.

Always use the smallest of the three measurements.

Measure the Height

Next, measure the height of the opening in three places:

• On the left side
• In the centre
• On the right side

Again, use the smallest measurement to ensure the window will fit within the opening.

Deduct for Fitting Tolerance

Once you have your final width and height, you need to allow for fitting tolerance.

As a general rule, deduct around 10mm from both the width and height. This gives enough space to position the frame, level it, and apply sealant.

Failing to allow for tolerance is one of the most common causes of tight or difficult installations.

Common Measuring Mistakes to Avoid

Even with experience, it is easy to fall into bad habits. Here are some of the most common mistakes we see when people measure uPVC windows.

Measuring from Plaster Instead of Brick

Always measure from the structural opening, not from internal finishes. Plaster can vary and does not give an accurate representation of the true size.

Assuming the Opening Is Square

Very few openings are perfectly square, especially in older buildings. That is why taking multiple measurements is so important.

Forgetting to Deduct Tolerance

Ordering the exact size of the opening without allowing space for fitting will cause problems. Always factor in the fitting gap.

Not Checking the Depth

Depth is often overlooked, but it matters. Make sure there is enough space for the frame and any additional components such as trims or boards.

Special Considerations for Different Installations

Not every job is the same, and some situations require extra care when measuring.

Replacement Windows

When replacing existing windows, it is important to check the condition of the opening once the old frame is removed. Do not assume everything will be square or consistent.

New Builds

New build openings are usually more consistent, but it is still important to confirm measurements rather than relying on drawings alone.

Older Properties

Older properties can be more challenging. Walls may not be straight, and openings may have shifted over time. Take extra care and allow for additional adjustments where needed.

When to Double Check or Ask for Help

There is no harm in taking a second look or asking for advice. In fact, it can save a lot of time and money.

If you are dealing with:

• An unusual opening
• A bay or shaped window
• Tight tolerances
• A large order where accuracy is critical

It is always worth double checking before confirming the order.

“We are always happy to sense check measurements. A quick call can prevent a lot of hassle later on.”
— Scott, Director at Nova Trade Frames

How Nova Helps You Get It Right First Time

At Nova Trade Frames, we understand how important accuracy is when ordering on a supply only basis.

That is why we support our customers throughout the process. From helping you understand how to measure uPVC windows properly, to manufacturing everything to your exact specification, our aim is to make the process as straightforward as possible.

We provide made to measure products, reliable lead times, and support when you need it, so you can focus on getting the job done.

Final Thoughts

Measuring uPVC windows correctly is one of the most important parts of any installation. It is also one of the easiest areas to get wrong if you rush or make assumptions.

By taking your time, following a clear process, and double checking where needed, you can avoid common mistakes and ensure every window fits as it should.

Getting it right first time saves time, protects your reputation, and keeps your projects running smoothly.

Ready to Order with Confidence?

If you are looking for a supplier that supports you every step of the way, Nova Trade Frames is here to help.

Apply for a trade account, request a quote, or speak to the team about your next project.

On the surface, many suppliers look similar. They all promise quality products, fast delivery, and competitive pricing. But in reality, the differences between them can have a huge impact on your business.

In this guide, we will walk through what to look for in a trade uPVC supplier, the common issues installers face, and how to make sure you are working with a supplier that supports your success.

Why Your Choice of Trade uPVC Supplier Matters

Your supplier is more than just somewhere you place orders. They play a key role in how efficiently your jobs run, how your customers perceive your work, and how profitable each project is.

If your supplier is unreliable, it affects everything. Late deliveries can delay installs, poor quality products can lead to callbacks, and unclear communication can waste valuable time on site.

We regularly speak to installers who have experienced these problems. Many of them only realise how much their supplier was holding them back once they switch.

A good trade uPVC supplier should make your job easier, not harder.

Do They Work Exclusively With the Trade?

This is one of the biggest factors to consider. Many companies claim to offer trade pricing, but also sell directly to homeowners.

This creates a problem. If your customer can go online and find the same product at a similar price, it weakens your position and makes it harder to justify your quote.

A true trade uPVC supplier works exclusively with professionals.

“We have always been clear that we are trade only. Our customers need to know their pricing is protected and they are not competing with us for their own jobs.”
— Scott, Director at Nova Trade Frames

Working with a trade-only supplier gives you confidence that your supplier is supporting your business, not competing with it.

If you are not already set up, it is worth taking a look at how a trade account works and the benefits it can bring to your day to day operations. If you feel like we’re a good fit, you can apply for a uPVC trade account.

Are Their Products Truly Made to Measure?

Every job is different. Accurate measurements and properly manufactured frames are essential for a smooth installation.

Some suppliers rely on standard sizes or lack precision in manufacturing, which can lead to issues on site. Frames that do not fit correctly can result in wasted time, additional labour, and unhappy customers.

A reliable supplier will provide fully made-to-measure products, built exactly to your specifications.

This is especially important when ordering uPVC windows supply only, where you are responsible for measuring and fitting. Having confidence that the product will fit first time makes a huge difference to how efficiently the job runs.

The result is simple. Faster installs, fewer adjustments, and less risk of costly remakes.

Can They Deliver Consistently and On Time?

Timing is critical in the trade. When materials do not arrive when expected, it can delay the entire project and impact other trades on site.

We have worked with installers who have had deliveries pushed back multiple times by previous suppliers. In one case, a small development was delayed because windows were not ready when promised, which caused a knock-on effect across the build.

Consistency is key. A good trade uPVC supplier will provide clear lead times and stick to them.

“Most issues we hear about come down to missed deadlines. We focus on being realistic with lead times and delivering when we say we will.”
— Scott, Director at Nova Trade Frames

When you know your delivery dates are reliable, you can plan your installs with confidence.

Do They Offer the Flexibility You Need?

No two projects are the same. Different properties require different styles, finishes, and specifications.

A strong trade uPVC supplier will offer a wide range of options, allowing you to meet the needs of each customer. This includes:

• A variety of window styles
• A full range of colours and finishes
• Flexible glazing options
• Hardware choices to suit different preferences

Having this flexibility means you can offer more to your customers without needing to source from multiple suppliers.

Whether you are ordering windows or trade uPVC doors, being able to customise your products helps you win more jobs and deliver better results.

Is Their Support Built Around Installers?

Support is often overlooked, but it is one of the most important aspects of working with a supplier.

When you are on site and need an answer quickly, you need a supplier who understands the urgency. Poor communication can lead to delays, confusion, and unnecessary stress.

A good trade uPVC supplier will provide:

• Fast and clear communication
• Help with specifications and ordering
• Advice when you are unsure about measurements or requirements

“If someone is unsure about a spec, we would rather they pick up the phone and ask. A quick conversation can prevent a lot of problems later.”
— Scott, Director at Nova Trade Frames

This level of support gives you confidence when placing orders and helps ensure everything runs smoothly.

Are They Helping You or Holding You Back?

Sometimes the biggest issue is not obvious at first. You might be used to delays, chasing updates, or dealing with inconsistent quality, and assume it is just part of the job.

But it does not have to be that way.

If your supplier is causing regular problems, it is worth asking whether they are helping your business grow or holding it back.

A good supplier should make things simpler. Orders should be straightforward, communication should be clear, and products should arrive ready to install.

If that is not your current experience, it may be time to look at other options.

Why Installers Choose Nova as Their Trade uPVC Supplier

At Nova Trade Frames, everything we do is built around supporting the trade.

We do not sell to the public, so our focus is entirely on installers, builders, and developers. Our products are made to measure, our lead times are reliable, and our team is here to help when you need it.

“Our customers rely on us to get it right first time. If we do our job properly, it makes their job easier.”
— Scott, Director at Nova Trade Frames

Final Thoughts

Choosing the right trade uPVC supplier is about more than price. It is about reliability, consistency, and having a partner you can trust.

The right supplier will help you complete jobs on time, avoid unnecessary issues, and deliver a better experience for your customers.

If you are currently dealing with delays, poor communication, or inconsistent quality, it might be time to review your options.

Ready to Work with a Supplier That Supports You?

If you are looking for a trade uPVC supplier that understands your needs, get in touch with Nova Trade Frames today.

You can apply for a trade account, request a quote, or speak to the team about your next project.

If you are still working with mixed suppliers or retail-focused companies, this shift is worth paying attention to. Here are seven clear reasons why installers across the UK are making the switch to trade only window and door suppliers like Nova.

1. More Control Over Jobs and Scheduling

One of the biggest frustrations on site is working around someone else’s timeline. When you rely on supply and fit packages or retail suppliers, you often lose control of when products arrive and how quickly issues are resolved.

With a supply only window and door supplier, you control the process. You measure, you order, and you install on your schedule.

Benefit: You plan jobs your way, not around someone else’s availability.
Result: Fewer delays, smoother installs, and better time management.

2. Better Margins on Every Job

Margins matter, especially with rising material and labour costs. When you buy through a supply only model, you remove unnecessary extras and keep control of your pricing.

You are not paying for bundled services you do not need, and you can set your own installation costs based on your experience and workload.

Benefit: Greater flexibility in pricing.
Result: More profit retained on each project.

3. No Competition from Your Own Supplier

This is a big one and often overlooked. Many suppliers advertise trade pricing but also sell directly to homeowners. That creates a situation where your customer can find the same product online and question your quote.

A true supply only window and door supplier works exclusively with the trade.

“We have always been clear on this. We do not sell to the public. Our customers need to know their pricing and their work is protected.”
— Scott, Director at Nova Trade Frames

Benefit: Your supplier supports your business, not competes with it.
Result: Stronger customer relationships and fewer pricing objections.

4. Faster, More Reliable Lead Times

Delays on materials can throw an entire project off track. When windows or doors do not arrive on time, it impacts other trades, pushes deadlines, and creates unnecessary stress.

Supply only suppliers are built around trade demand. That means faster turnaround times and clearer communication.

Benefit: Products arrive when expected.
Result: You stay on schedule and keep projects moving forward.

5. Made to Measure Products That Fit First Time

Every job is different. Off-the-shelf solutions often lead to adjustments on site, wasted time, and sometimes costly rework.

With a dedicated supply-only window and door supplier, everything is made to your exact specification.

We have worked with installers who switched after repeated fitting issues elsewhere. Once they moved to made to measure supply, their install times dropped and callbacks reduced significantly.

Benefit: Accurate products built to your measurements.
Result: Faster installs and fewer problems on site.

6. Better Support When You Need It

Not all suppliers understand the pressures of working on site. When something goes wrong or you need advice, slow responses can cause real problems.

Working with a trade-focused supplier means you are dealing with people who understand your world. They know what matters and respond accordingly.

“We are not just here to take orders. If a customer needs help with a spec or a measurement, we would rather spend five minutes on the phone than see them run into trouble later.”
— Scott, Director at Nova Trade Frames

Benefit: Access to knowledgeable support.
Result: Fewer mistakes and more confidence when ordering.

7. Ability to Offer More to Your Customers

Homeowners expect more choice than ever before. Whether it is colour, style, or glazing options, having flexibility helps you win more work.

A good supply only window and door supplier will offer a wide range of products that can be tailored to each job.

This allows you to present better options to your clients without needing multiple suppliers.

Benefit: Greater product choice and flexibility.
Result: More competitive quotes and higher customer satisfaction.

Final Thoughts

Switching to a supply only window and door supplier is not just a trend. It is a smarter way of working for many trade professionals.

It gives you control, protects your margins, and helps you deliver better results for your customers.

At Nova Trade Frames, we have built our business around supporting installers. We focus on reliability, clear communication, and making sure every order is right first time.

If you are looking to simplify your supply chain and improve how you work, it might be time to make the switch. Apply for a trade account today!

That difference can cost you jobs.

In this blog, we’ll break down why choosing the right trade window supplier matters, the problems installers regularly face, and how working with a trade-focused partner like Nova helps you avoid them.

What Is a Trade Window Supplier?

A true trade window supplier works exclusively with professionals. That means installers, builders, developers, and contractors. They don’t sell directly to homeowners, and they don’t advertise retail pricing.

Everything they do is built around the needs of the trade. That includes faster lead times, made-to-measure products, and support that actually understands how sites operate.

On the other hand, many suppliers sit somewhere in the middle. They promote trade pricing, but they also sell directly to the public. That’s where problems start.

The Problem with Retail-Focused Suppliers

At first, using a supplier that sells to both trade and retail might not seem like an issue. But in reality, it creates a number of challenges that can affect your business.

One of the biggest issues is pricing transparency. If a homeowner can go online, find the same product, and get a similar price to what you’re paying, it becomes much harder to justify your quote.

We’ve seen this happen time and time again.

A Nova customer recently told us about a job where they had quoted for a full window replacement on a residential property. The homeowner decided to “do a bit of research” and found a supplier online offering what looked like the same windows. The price difference created doubt, even though the installer was factoring in labour, experience, and aftercare.

In the end, the installer had to spend extra time explaining the value of their service just to keep the job.

That situation could have been avoided entirely with a true trade window supplier.

“If your customer can go online and see the same product at a similar price, you’re already on the back foot. That’s not how a trade relationship should work.”
— Scott, Director at Nova Trade Frames

Why Trade Installers Should Avoid Retail Suppliers

Working with the wrong supplier does not just affect pricing. It can impact every stage of your job.

Retail-focused suppliers are often not set up to support trade customers properly. That can lead to slower communication, longer lead times, and less flexibility when things need to change.

Another common issue is stock and scheduling. Retail suppliers tend to prioritise volume sales, which can mean delays when you need products delivered to fit a specific install date.

We’ve had installers come to us after experiencing exactly this.

One builder was working on a small development and had ordered windows from a supplier that also sold to the public. The delivery was pushed back twice due to stock issues. This delayed the entire project and affected other trades on site.

By the time they came to Nova, their main priority was simple. They needed reliability.

“Most of our customers come to us after a bad experience somewhere else. It’s usually down to poor communication or missed deadlines. That’s what we focus on getting right.”
— Scott, Director at Nova Trade Frames

The Benefits of Using a Trade Window Supplier

Choosing a dedicated trade window supplier changes how you work for the better. It gives you more control, more confidence, and a smoother process from start to finish.

Protected Pricing

With a trade-only supplier, your pricing is your pricing. Your customers cannot go behind your back and find the same products online. That protects your margins and your relationship with the client.

Faster, More Reliable Lead Times

Trade suppliers understand that timing is critical. Products are manufactured and delivered with installers in mind, not retail demand.

That means fewer delays and better planning for your jobs.

Better Communication

When you call a trade supplier, you are speaking to people who understand what you need. They know the importance of measurements, specifications, and deadlines.

You are not explaining your job to someone who mainly deals with homeowners.

Made-to-Measure as Standard

Every job is different, and a trade window supplier works to your specifications. That reduces issues on site and helps ensure everything fits first time.

Why Installers Choose Nova Trade Frames

At Nova, everything we do is built around being a reliable trade window supplier.

We do not sell to the public. We do not publish retail pricing. Our focus is 100 percent on supporting trade customers.

That means:

• Made-to-measure uPVC windows and doors
• Fast and reliable delivery
• Clear, honest lead times
• Support with specifications and ordering
• A team that understands the pressures of working on site

But more importantly, it means consistency.

We know that when you place an order, you are relying on us to help you deliver a job on time and to a high standard.

“Our customers are putting their name to every install. If we let them down, it reflects on them. That’s why we take reliability seriously.”
— Scott, Director at Nova Trade Frames

Real Results from Choosing the Right Supplier

We’ve worked with installers who have completely changed how they operate simply by switching to a dedicated trade supplier.

One installer we work with regularly had previously been using a mix of suppliers, including some that sold to homeowners. They found themselves constantly chasing updates, dealing with inconsistent quality, and losing time on site.

After moving everything over to Nova, they simplified their process.

They now order all of their windows and doors through one supplier, know exactly what lead times to expect, and spend less time dealing with problems.

For them, the biggest benefit was not just the product. It was the peace of mind.

Final Thoughts

Choosing the right trade window supplier is not just about price. It is about reliability, support, and protecting your business.

A supplier that sells to both trade and retail might seem convenient at first, but it often creates more problems than it solves.

Working with a dedicated trade supplier like Nova means you stay in control. Your pricing is protected, your timelines are clearer, and your installs run more smoothly.

If you are serious about growing your business and delivering consistently high standards, your supplier should be working with you, not against you.

Whether you’re a seasoned installer or managing a multi-property build, this guide walks you through the most common pitfalls and how to avoid them. Getting it right the first time means happier clients, smoother installs, and more profit left in your pocket.

Trade Double Glazed Windows Mistake 1. Incorrect Measurements

Let’s start with the big one. Measurement mistakes are the number one reason why windows don’t fit on the day of install. Common problems include:

• Measuring from the plaster line rather than the brickwork
• Not allowing fitting tolerance (deducting 10mm for adjustment)
• Assuming the opening is square
• Mixing up frame size and aperture size

A window that’s just 5mm too big won’t fit without taking out more brickwork. A window that’s too small will leave large gaps and compromise the fit.

How to avoid it:
Always measure brick-to-brick in three places for both width and height (top, middle, bottom), then use the smallest measurement. Deduct 10mm for fitting tolerance, and clearly specify whether the measurement is the actual frame size or the aperture size. If you’re unsure, double-check with your supplier before ordering.

“We see it time and time again, a great job delayed over 10mm. Taking an extra few minutes on the measurement can save hours later.”
— Scott, Director at Nova Trade Frames

Trade Double Glazed Windows Mistake 2. Confusing Hinge and Opening Directions

It sounds simple, but getting left and right opening directions mixed up is another common issue. The problem usually happens when the spec is written from an internal perspective, while manufacturers work from an external view.

Imagine a window designed to open outwards from the left.

If the order describes that from the inside looking out, you’ll end up with the opposite result.

How to avoid it:
Always specify hinge and handle positions from the outside of the building. Use clear terms like “left-hand opening” or “top-hung”, and include diagrams if needed. When in doubt, send over a sketch or photo to your supplier for confirmation.

Trade Double Glazed Windows Mistake 3. Overlooking Compliance with UK Building Regulations

Installing windows that don’t meet current building standards is a fast way to trigger failed inspections, unhappy clients, or even legal issues. All trade double glazed windows should meet Part L of UK building regulations for thermal efficiency. You may also need to consider:

• Fire escape routes (especially for upstairs windows)
• Safety glass requirements in doors or low-level glazing
• Trickle vents in habitable rooms

How to avoid it:
Make sure your supplier understands the latest regs and supplies frames that meet them as standard. At Nova, all of our uPVC windows are A+ rated and Part L compliant, with options to upgrade to laminated or toughened glass where needed. If you’re unsure, just ask, we’ll walk you through the spec.

Trade Double Glazed Windows Mistake 4. Forgetting Key Glazing and Hardware Details

Window installations are more than just frames. Forgetting about the smaller details can lead to delays, reordering, or disappointment when the product arrives. Common oversights include:

• Not specifying obscure glass for bathrooms
• Forgetting to request trickle vents or restrictors
• Ordering the wrong colour handles or finish
• Overlooking child safety features or fire egress options

How to avoid it:
Create a quick checklist of must-haves for every window order. Include glazing type, handle colour, vent position, safety features, and special requirements like easy-clean hinges or equal sightlines. A good supplier will prompt you for these, but it’s always worth double-checking yourself.

Trade Double Glazed Windows Mistake 5. Using the Wrong Type of Supplier

Not all suppliers are trade-friendly. Some companies offer “trade discounts” but also sell directly to homeowners. This means your clients can shop around, find similar prices, and potentially cut you out of the job.

Worse still, many retail-focused suppliers don’t understand the demands of trade work. Lead times are longer, communication is poor, and you’re often stuck waiting for stock that doesn’t arrive when you need it.

How to avoid it:
Choose a supplier that works exclusively with trade professionals and has a great reputation. At Nova, we’re trade-only, no retail customers, no undercutting, and no DIY quotes.

That means you stay in control of the pricing, the spec, and the schedule.

Trade Double Glazed Windows Mistake 6. Not Asking for Help When You Need It

You might be an experienced installer, but window specs are constantly evolving. Whether it’s a new regulation or a bespoke opening style, guessing can be risky — and expensive.

How to avoid it:
Work with a supplier who will support you, not just sell to you. At Nova, we’re happy to take calls, check drawings, or advise on tricky measurements. You’re not just placing an order, you’re partnering with a team that wants your install to go smoothly.

“We’re not here to tell people how to do their job, just to help them avoid problems we’ve seen before. It’s in everyone’s interest that the job goes right first time.”
— Scott, Director at Nova Trade Frames

Final Thoughts

Ordering trade double glazed windows should be a straightforward process — but the details matter. A small oversight in measurement, glazing, or hardware can turn into a big problem on site.

That’s why working with the right supplier, one who truly understands trade needs, makes all the difference.

At Nova Trade Frames, we specialise in helping installers, builders, and developers get it right. From made-to-measure frames and quick turnaround times to expert support on every order, we’ve built our reputation on being reliable, professional, and trade-first.

It gives you full control of the installation, better profit margins, and a quicker, cleaner workflow. But while the benefits are clear, it’s not without its risks.

Order from the wrong supplier or make minor mistakes in the specifications, and you could face delays, remakes, or a frustrated customer.

In this blog, we’ll break down the benefits of uPVC windows supply only, what to look for in a supplier, and just as importantly, what to avoid.

What Does ‘uPVC Windows Supply Only’ Actually Mean?

Choosing supply only means you’re buying your uPVC windows without fitting services included.

As the installer or contractor, you take care of the measuring, ordering, and fitting, and that’s exactly how many professionals prefer it.

You’re not tied to someone else’s schedule, you can manage your costs, and you have full visibility over the product spec and delivery. It’s flexible, streamlined, and puts you in charge of the job.

“We only work with trade customers, so everything we do is built around speed, accuracy, and ease of installation. Supply-only gives our clients full control, and they know they’re not being undercut by us selling direct to homeowners.”
— Scott, Director at Nova Trade Frames

Six Reasons Trade Installers Prefer uPVC Windows Supply Only

Whether you’re fitting for a homeowner, developer or landlord, here’s why more trade professionals are choosing the supply-only route with confidence.

1. Faster Turnaround Times = Less Downtime on Site

One of the biggest frustrations for installers is waiting on delayed deliveries or dealing with vague lead times.

When you work supply-only with a trade-first supplier, you’re in control of when and how your materials arrive.

At Nova, our streamlined production process and trade-priority system mean you get your frames delivered on time, direct to site, so your schedule stays on track.

Benefit: No delays or rescheduling headaches
Solution: Fast, reliable lead times to keep your projects moving forward

2. Lower Costs and Better Margins = More Profit per Job

When you handle the install and buy directly through a trade supplier, you cut out unnecessary markups and labour costs associated with supply-and-fit packages.

This allows you to price your own labour and protect your profit margin. With Nova, there are no hidden charges or inflated prices, just competitive, trade-only pricing on every order.

Benefit: You control your pricing, profits, and package
Solution: Buy supply-only and price your services independently for better job profitability

3. Installer-Friendly Products = Quicker, Cleaner Installs

Some windows look good on paper but are a nightmare to fit.

Ours are built with trade feedback in mind, lightweight, precise, and easy to handle on-site. You get pre-configured frames that match your spec exactly, with clear labelling and minimal need for adjustment.

Benefit: Less faffing about on-site, more time for quality installs
Solution: Pre-manufactured to your exact measurements for efficient, accurate fitting

4. Fully Compliant with Building Regulations = Peace of Mind and Fewer Callbacks

All supply-only uPVC windows from Nova meet the latest Part L regulations as standard, meaning your installations will pass building control inspections without issue.

Our profiles are A+ energy rated, and we offer various glazing and safety upgrades as needed.

Benefit: Confidence in every install
Solution: Fully certified products that meet all thermal and safety regulations, reducing the risk of post-fit issues

5. Total Customisation = The Right Look for Every Project

Homeowners expect more choice than ever before, and when you’re working on extensions or new builds, having a wide selection of colours, finishes and opening styles matters.

Our supply-only service allows you to specify every detail: frame colour, style, glazing, hardware and opening direction. From anthracite grey flush sash windows to obscure glass for bathrooms, every detail is up to you. We work with window manufacturers offering the best choice available.

Benefit: Win more jobs by offering tailored solutions
Solution: Made-to-measure frames built to your exact spec, every time

6. Trade-Only Supply = No Public Pricing or Undercutting

Some suppliers offer “trade” pricing but also sell direct to the public.

This causes confusion, undercuts your pricing, and often leads to slow or unreliable trade support.

At Nova, we only sell to trade customers. That means no retail price lists, no DIY buyers calling us for quotes, and no risk of losing the job to your own supplier.

Benefit: Your pricing and customer relationship stays protected
Solution: A genuine trade-only supplier you can rely on for support, not competition

What to Look For in a uPVC Window Supplier

When you’re sourcing uPVC windows supply only, your supplier is more than just a manufacturer – they’re an extension of your business. The wrong supplier will slow you down, frustrate your clients, and hurt your reputation.

The right one will help you deliver consistently high standards, on time, with zero drama. Here’s what to look for and why it matters.

Trade-Only Access

Many so-called “trade suppliers” also sell to the public.

This creates a frustrating situation where homeowners can access the same products at similar prices, undermining your role and often cutting you out of the loop.

Choose a supplier like Nova that works exclusively with verified trade professionals.

Benefit: You stay in control of the client relationship and pricing, with the confidence that your supplier is backing you – not competing with you.

Accurate, Made-to-Measure Manufacturing

Off-the-shelf windows or poorly measured frames are a recipe for callbacks, delays, and site issues.

Even a few millimetres out can mean a frame that doesn’t fit. Nova builds every window to your exact measurements, confirmed by a dedicated team.

Benefit: Frames fit first time. No onsite trimming, no delays, no reorders – just fast, clean installs that protect your reputation.

Fast, Reliable Lead Times

Delayed deliveries disrupt the job schedule, hold up follow-on trades, and leave you answering awkward questions from your clients. Nova lead times are fast, accurate, and communicated up front.

Benefit: You can plan your installs with confidence and avoid wasting labour hours waiting on late deliveries.

Full Product Flexibility

Limited product options mean you either compromise the spec or waste time shopping around. Nova offers a full range of styles, colours, hardware, and glazing.

Benefit: Win more jobs by offering better customisation and keep clients happy with one trusted supplier.

Help With Spec, Compliance and Regulations

Not all installers have time to dig through energy ratings or building regulation updates – but failure to comply (especially with Part L) can lead to failed inspections.

All Nova windows are Part L compliant as standard, and we’re on hand to answer your questions.

Benefit: Peace of mind knowing your supplier understands the compliance landscape and has your back.

Clear Communication and Trade Support

Poor communication leads to uncertainty, confusion, and sometimes lost jobs. Nova prioritises clear documentation, rapid responses, and dedicated support.

Benefit: You get the answers you need, when you need them – so you can focus on fitting, not chasing up deliveries.

“We’ve worked in this industry for over 40 years, and we know what matters to installers. We’re not just here to sell windows – we’re here to help our trade customers grow their business.”
— Scott, Director at Nova Trade Frames

Common Pitfalls to Avoid When Ordering uPVC Windows Supply Only

Ordering uPVC windows supply only gives you greater control and flexibility, but it also puts more responsibility on your shoulders.

At Nova, we’ve seen how small oversights can lead to delays, rework, and even lost revenue. Here’s what to watch out for – and how to avoid them.

Incorrect Measurements

This is by far the most common issue with supply-only windows.

Measuring too tight to the aperture, misunderstanding internal vs external dimensions, or assuming square openings can all lead to ill-fitting frames.

Avoid it: Always measure brick-to-brick, not plaster-to-plaster. Take three measurements for width and height (top, middle, bottom) and use the smallest. Deduct 10mm to allow for fitting tolerance and mark whether measurements are for the aperture or frame size.

Confusing Hinge and Opening Directions

It’s easy to mix up left and right-handed openings, especially when standing inside.

Avoid it: Always specify hinge and handle positions from the outside looking in. Use terms like “top hung” or “side hung” and include simple sketches if needed.

Missing or Incorrect Hardware Details

It’s easy to forget about glazing, handle colours, or trickle vents until the unit arrives.

Avoid it: Confirm hardware and glazing details before placing the order. For bathrooms, specify obscure glass. For doors or low-level windows, confirm safety glazing is included.

Ordering Non-Compliant Specifications

Not all suppliers build to current UK standards. Installing non-compliant frames could lead to failed inspections.

Avoid it: Ensure your supplier is building to Part L and other relevant UK building regs. Nova windows are compliant as standard – and we’re happy to provide technical confirmation.

Choosing a Retail-Focused Supplier

Some suppliers claim to offer trade prices but also sell to the public. This causes pricing conflicts and undermines your quotes.

Avoid it: Work with a supplier like Nova that serves the trade exclusively and offers protected pricing and dedicated trade support.

Not Asking for Help When Unsure

It’s tempting to guess or rush – but a 5-minute call could save a £500 remake.

Avoid it: Speak to your supplier. Ask about anything you’re unsure of and use their expertise to double-check unusual orders.

“We’re happy to jump on the phone to walk through your order with you. Better to check early than rework later.”
— Scott, Director at Nova Trade Frames

In this guide, we’ll explore what makes uPVC such a popular option, how it compares to traditional materials like timber, and why Nova’s trade-only, supply-only service is trusted by professionals across the UK.

What are uPVC Windows and Doors?

uPVC stands for unplasticised polyvinyl chloride. It’s a rigid, long-lasting material that’s become the industry standard for window and door frames thanks to its thermal performance, low maintenance, and cost-efficiency.

Unlike timber, uPVC doesn’t warp, rot, or need painting. And unlike aluminium, it won’t suffer from cold bridging or require additional coatings.

It’s a versatile material that works just as well on modern new-builds as it does on traditional refurbishments, especially when paired with a wide range of colour finishes and glazing styles.

The Benefits of uPVC Windows and Doors for Trade Professionals

uPVC windows and doors offer a range of benefits that make them ideal for trade installations.

Compared to timber, uPVC provides greater durability and far less ongoing maintenance.

While timber doors and windows require regular treatment, painting, and are prone to movement over time, uPVC stays stable and weather-resistant with minimal upkeep.

This saves you time on site, reduces the risk of future callbacks, and ensures consistent results for your customers.

uPVC windows and doors also deliver excellent thermal efficiency.

With multi-chambered profiles and high-performance glazing, they help reduce heat loss and meet or exceed current building regulations for energy performance.

This not only helps your clients save on energy bills but also supports improved EPC ratings on residential developments.

For trade professionals, the benefits go beyond the product itself. uPVC is lightweight, easy to handle, and simple to fit. It requires no special treatment before installation, allowing you to complete jobs faster and with less hassle.

Why Trade Customers Prefer Supply-Only uPVC Windows and Doors

Supply-only is the preferred route for many installers and developers, and with good reason. When you buy uPVC windows and doors on a supply-only basis, you get full control over the installation process. You choose what you need, when you need it, and fit it according to your schedule.

This flexibility helps reduce delays, increase margins, and streamline your workflow. There’s no waiting around for fitters or navigating extra charges from retail suppliers. You stay in control from quote to completion.

At Nova, we work exclusively with the trade. That means:

• No public sales
• No inflated pricing
• No competing interests

Just made-to-measure products, reliable turnaround, and support from a team that understands the demands of working on site.

• Casement windows

In this guide, we break down everything you need to know about buying uPVC windows for trade, from how supply-only works to what sets a good supplier apart.

What Are Trade uPVC Windows?

Trade uPVC windows are designed, priced, and supplied specifically for trade professionals.

That means you’re buying directly from the manufacturer or a trade-only distributor like Nova, without any inflated retail pricing or unnecessary installation services.

Unlike buying from DIY stores or public-facing websites, trade windows give you access to preferential pricing, custom specifications, professional support, and delivery options that are built around the needs of installers and developers.

They’re ideal for professionals who want control over fitting, clear communication, and dependable supply every time.

Why More Installers Are Choosing Supply Only

The supply-only model has become the first choice for many in the trade. It gives installers more control, more flexibility, and fewer delays.

When you buy supply only, you are in charge of the installation schedule.

You don’t have to coordinate with a separate fitting service, which means you can complete projects faster and more efficiently. Supply-only also keeps your costs lean, giving you the room to build healthier margins or pass savings on to your clients.

At Nova, we work exclusively with trade professionals. That means we never sell to the public, and we’re fully focused on helping you get what you need, when you need it, without unnecessary delays or distractions.
