Homeowners like them because they create a cleaner, brighter connection between the inside and outside of a property. Installers like them because they offer a premium product with strong demand and good project value.
But when it comes to quoting, one of the first questions customers usually ask is simple: how much do aluminium bi-fold doors cost?
The honest answer is that aluminium bifold doors prices can vary depending on a number of factors. Size, number of panels, colour, glazing, threshold choice, hardware and specification can all affect the final price.
For trade installers, understanding these factors makes it easier to quote accurately, explain value to customers and avoid pricing mistakes.
Why Aluminium Bifold Doors Are a Premium Product
Aluminium bi-fold doors usually sit at the more premium end of the window and door market. Compared with standard uPVC options, aluminium offers slimmer sightlines, stronger frames and a more modern overall finish.
Because aluminium is naturally strong, it allows for larger glass areas and slimmer frames. This is one of the biggest selling points for homeowners. They get more natural light, better views and a cleaner look.
Modern aluminium systems also offer strong thermal performance, smooth operation and a durable finish that works well on both contemporary and traditional properties.
For installers, this means aluminium bi-fold doors can help position a project as higher value. They are not always the cheapest option, but they often deliver the look and performance customers are willing to pay more for.
Size and Number of Panels
One of the biggest factors affecting aluminium bifold doors prices is the size of the opening.
A smaller two-panel bi-fold door will cost less than a wider four, five or six-panel system. That is because larger openings require more material, more glass, more hardware and more manufacturing time.
The number of panels also matters. Each additional panel adds cost, but it also changes how the doors operate. Some customers may want a traffic door for everyday access, while others may prefer a full opening system that folds back completely.
For installers, it is important to understand how the door configuration affects both price and usability. The cheapest configuration is not always the best option for the customer’s lifestyle or property.
Colour and Finish Options
Colour choice can also affect the final price.
Standard colours are often more cost-effective, while specialist colours or dual colour options may increase the cost. Anthracite grey, black and white remain popular choices because they suit modern extensions and garden rooms particularly well.
The finish matters too. Powder-coated aluminium provides a durable, clean appearance that is designed to stand up to everyday use and weather exposure.
When quoting, installers should always confirm the customer’s preferred colour early. This avoids surprises later and helps keep the quote accurate from the start.
Glazing Specification
Glazing is another key factor in aluminium bi-fold door pricing.
Most homeowners expect good energy performance as standard, but some projects may require upgraded glazing. This could include toughened glass, laminated glass, solar control glass or acoustic glass, depending on the property and how the space will be used.
Larger panes of glass can also affect cost because they require careful handling and stronger overall specification.
For trade installers, glazing should never be treated as an afterthought. It affects price, performance, compliance and the finished customer experience.
Thresholds, Hardware and Security
The smaller details can also influence aluminium bifold doors prices.
Threshold choice is a good example. Some customers may want a low threshold for easier access between the house and garden. Others may prioritise weather performance, depending on where the doors are being installed.
Hardware also matters. Handles, locking systems, hinges, rollers and security features all play a part in how the finished doors look, feel and perform.
This is where product quality becomes important. A cheaper bi-fold door system might look acceptable at first, but poor hardware or rough operation can quickly lead to complaints.
Modern premium systems, such as Sheerline aluminium profiles, are designed to give installers and homeowners confidence in both performance and usability.
Supply Only vs Supply and Fit
For trade installers, supply only aluminium bi-fold doors can be a strong option.
With supply only, you are in control of the installation, customer relationship and labour pricing. You can quote the job your way and protect your margin.
This can be especially useful when working with homeowners who already trust you to manage the full project. Rather than sending them to a retail supplier, you can source the product through a trade supplier and keep control of the process.
Nova supplies aluminium bi-fold doors for trade installers on a supply only basis, helping you access the right products while keeping the installation in your hands.

Why Installers Should Avoid Quoting on Price Alone
It can be tempting to focus purely on the lowest price, especially when customers are comparing quotes. But with aluminium bi-fold doors, the cheapest option is not always the best value.
Poor quality doors can lead to fitting issues, stiff operation, weaker thermal performance and customer complaints. Delays can also cost installers money if projects are held up or return visits are needed.
A better approach is to explain the value clearly. Homeowners are not just paying for a door. They are paying for the appearance, smooth operation, energy performance, security, durability and the confidence that the installation has been done properly.
For installers, using a reliable trade supplier helps protect both your quote and your reputation.
