How Much Do Bi-Fold Doors Cost in the UK? (2026 Prices)

Bi-fold doors are a very popular option for UK homeowners, as they provide lots of natural light to enter the home and effortlessly connect the indoors to the outdoors. But a key question that’s asked before homeowners decide to get them installed is, how much do bi-fold doors cost?

The answer to this key question is, it depends. There are various factors that affect the cost of bi-fold doors in 2026, from the material type and size to the glazing and whether or not they are brand new or preloved.

This guide breaks everything down and provides the information you need to know how much different bi-fold doors cost.

What Are Bi-Fold Doors?

Bi-fold doors consist of multiple glazed panels that fold and slide neatly to one or both sides along a tracked system. Their slim frames and large glass panels maximise natural light while creating a seamless connection between indoor and outdoor spaces, making them a popular choice for modern UK homes.

Average Bi-Fold Door Prices in the UK (2026)

In the UK, the cost of bi-fold doors typically ranges from around £1,000 to £7,000+. The price range varies due to several factors and specifications, such as the material, size and even the brand, which can affect the final cost. You also need to factor in labour costs for installation, which will also depend on the installer you choose.

What Affects the Cost of Bi-Fold Doors? 5 Considerations

1. Material

The first thing that affects the price of bi-fold doors is what material they’re made from. Aluminium and uPVC are both the most popular material choices, each with their own benefits, styling and maintenance requirements. Timber is also another option, and each material will differ in price, generally with aluminium and timber being more expensive than upvc bi-fold doors.

Choosing the right material isn’t just important for your initial investment but also for future maintenance, which can increase costs over the door’s lifespan. Here’s a quick display of the typical prices for each material:

• Aluminium bi-fold doors: £1500 per aluminium door leaf, depending on size and brand
• uPVC bi-fold doors: 3-5 panel configurations ranging approximately £2,000-£5,000
• Timber bi-fold doors: 3-5 panel configurations ranging approximately £2,500-£6,000

2. Door Size and Configuration

The bigger the bi-fold doors are, the more you will pay. Bi-fold doors must feature a minimum of two panels, but they can feature more complex configurations and panels which will increase the price. So, if you’re after a very expansive opening configuration with multiple panels, with increased height, it’s going to cost more.

3. Glazing Specification

The glazing type used for each panel is also a prominent factor that affects how much bi-fold doors will cost. Double glazing is often standard in 2026, but upgrading to triple glazing will add more onto the final price. There are also additional glazing options you might want to choose, such as tinted glazing and laminated glass to prevent shattered shards in the event of breakage, as well as anti-marking and anti-fingerprint treatments.

While you’ll have a more custom glazing that suits your living needs, the more options you choose will result in a higher final price.

4. Brand and Manufacturer

Different brands and manufacturers will also sell bi-fold doors at different price points. Premium manufacturers and specialist systems will be of a higher quality, requiring less maintenance and having better energy-efficiency ratings, ultimately meaning more spending from you, the consumer.

5. Installation Costs

While you may think that installing bi-fold doors yourself can save you money, unless you actually know what to do, seeking professional installers is always the best option. You’ll likely end up making costly mistakes if you decide to DIY the installation.

Brand-New vs Preloved Bi-Fold Doors

Homeowners don’t always have to choose brand new. To keep costs lower, opting for preloved bi-fold doors is a very good choice to make. Both new and preloved doors offer excellent benefits.

Brand-new doors provide the latest designs, warranties and complete customisation, while preloved bi-fold doors are a more affordable, sustainable option that helps reduce waste. When buying second-hand, check the doors for damage, smooth operation, glazing condition and the quality of the frames and hardware to ensure they’ll perform reliably for years to come.

Additional Costs to Consider

In addition to the size and configuration of the doors, the materials the frames are made from, glazing, the brand and installation costs, it’s also important to consider further costs that may be involved.

These include delivery, potential building alterations, options for hardware upgrades and other custom options like blinds. Future maintenance, especially for materials like timber, should also be considered.

The biggest saving here is if you purchase your bi-fold doors first and then make the opening based on your purchase. 

Are Preloved Bi-Fold Doors Worth It?

Preloved bi-fold doors can offer exceptional value, particularly if you’re looking to reduce costs without compromising on quality. Preloved doors can cost thousands of pounds less than brand-new ones, and many second-hand doors have plenty of life remaining.

Before purchasing, look for information regarding the grade and inspect the frames, glazing, hinges, rollers and locking mechanisms for signs of damage or excessive wear if possible. Buying from a reputable supplier like ourselves means that you’ll be receiving quality assurance with each purchase.

How to Choose the Right Bi-Fold Doors

The right bi-fold doors depend on your budget, property and how you plan to use the space. Consider the material, glazing, opening configuration and overall size to ensure the doors complement your home while providing the level of thermal efficiency and natural light you want.

Security is equally important, so look for high-quality locking systems and durable frames to protect your property. If you’re unsure where to start, read our guide on whether bi-fold doors are secure to learn more about the security features to look for.

And as we discussed, it’s easier and cost-effective to buy your bifold doors first and build around them or adapt your door opening based on their size.
