How much do bifold doors cost by size?
The opening width is one of the biggest price drivers for bifold doors.
Here are typical supply-and-fit costs for standard sizes using aluminium, the most common material choice for external bifolds:
Opening width | Typical cost |
|---|---|
Up to 3m (3-panel) | £3,000–£4,500 |
3–4m (3–4 panel) | £4,500–£5,500 |
4–5m (4–5 panel) | £5,500–£6,500 |
5m+ (5+ panels) | £6,000–£7,500+ |
These are indicative ranges for aluminium. uPVC doors are generally less expensive than aluminium, while timber prices vary depending on the timber species and finish.

How much does installation cost?
Installation typically costs £600–£1,200 in labour, depending on the size of the doors and the complexity of the project.
Because bifold doors are large and heavy, installers normally work in pairs to ensure the doors are fitted safely and accurately.
A straightforward installation usually takes around one day, although larger installations or projects involving structural alterations may take longer.
What affects the cost of bifold doors?
Several factors influence the final cost of installing bifold doors.
Material
The material you choose has one of the biggest impacts on price:
uPVC is usually the most affordable option and offers good durability with minimal maintenance
Timber provides a traditional appearance that's well suited to period properties but requires regular upkeep
Aluminium is typically the premium choice, offering slim frames, strength and excellent durability
Opening size
Larger openings require larger door sets and usually more panels, increasing both material and installation costs.
If you're creating a new opening rather than replacing existing doors, additional structural work may also be required.
Number of panels
Bifold doors are available in a range of configurations.
Generally, the more panels you choose, the higher the overall cost.
Quality and specification
Premium glazing, enhanced security, upgraded hardware and bespoke finishes will all increase the price.
Installation complexity
Straightforward replacements are generally less expensive than projects requiring alterations to the opening or additional structural work.
If a new lintel is required, budget around £650–£1,000, depending on the size and complexity of the work.
Your location
Labour rates are generally higher in London and the South East than elsewhere in the UK.
On Checkatrade, you'll only find trades who meet our high standards and pass up to 12 checks.
Additional bifold door costs
Depending on your project, you may need to budget for some additional costs.
Potential extras include:
Glass tinting (around £60–£170 per m²)
Removing and disposing of existing doors
Decorating and making good surrounding plasterwork
Structural alterations to create a new opening
Converting a window or French doors into bifold doors
What is the best material for bifold doors?
The best material depends on your budget, the style of your property and the level of maintenance you're happy to undertake.
Aluminium
Aluminium bifold doors offer slim sightlines, excellent strength and very little maintenance, making them one of the most popular choices for modern homes.
Typical cost for 3-5 panel aluminium bifold doors supplied and installed: £3,000–£7,500.
uPVC
uPVC bifold doors are an affordable, low-maintenance option available in a wide range of colours and finishes.
Typical cost for 3-5 panel uPVC bifold doors supplied and installed: £2,000–£4,500.
Timber
Timber bifold doors provide a traditional appearance that's particularly suited to older and period properties. They require regular maintenance but offer a distinctive natural finish.
Typical cost for 3-5 panel timber bifold doors supplied and installed: £3,500–£8,000+.
Composite
Composite bifold doors combine different materials to improve durability and reduce maintenance requirements.
They can be a good middle ground if you're looking for a balance between appearance, performance and longevity.
Bifold doors vs sliding doors: which costs more?
If you're deciding between bifold and sliding doors, cost is only one part of the picture.
Sliding doors often work out slightly cheaper for wider openings because they have fewer moving parts and are generally quicker to install.
Bifold doors, however, fold neatly to one side, creating a much wider opening between your home and garden. That's why they're a popular choice for kitchen extensions and open-plan living spaces.
Both styles are available in aluminium, uPVC and timber.
If you're still deciding, it's worth reading our guides on patio door replacement, French door costs and the cost of replacing a window with French doors before requesting quotes.

FAQs
Most homeowners spend between £3,000 and £7,500 on bifold doors supplied and installed, depending on the material, size and number of panels. Premium installations can cost considerably more.
Installation labour typically costs £600-£1,200, depending on the size of the doors and the complexity of the work.
Bifold doors flood your space with light and give excellent views of your garden during colder months. When the weather's warm, open them to fill your home with fresh air and create an extended indoor-outdoor living space. They're a very desirable feature and can add value to your home, making them a practical choice for conservatory installation alternatives or large rear extensions. All in all, bifold doors are a wise choice and offer so much in terms of aesthetics and practicality.
Unless you're an experienced DIY enthusiast, it's always best to hire an experienced fitter for bifold door installation. It's not a simple job and you'll need in-depth knowledge to install bifold doors safely and efficiently. If they're not installed properly, you could compromise the weatherproofing and security of your home. Bifold doors are heavy and will need at least two people with physical strength to carry out the installation. There's a potential for injury when working with large, heavy bi-folding doors.
Bifold doors are still popular, but sliding doors have grown as an alternative, particularly for very wide openings, because they take up less floor space when open and often cost less. Bifolds remain a strong choice where you want the widest possible opening and direct garden access without a raised threshold.
The main drawbacks are cost (higher than most door types), the space panels need to fold inward, and more moving parts that require regular maintenance. In exposed locations, sealing quality also matters more than with a solid door. That said, a well-fitted set from a reputable installer should give decades of reliable use.
A 3-panel aluminium bifold door for a 3m opening typically costs £3,000–£4,500 supplied and fitted. uPVC for the same opening starts from around £1,800–£3,000. Prices vary with glazing spec, hardware finish and whether structural work is needed.
Replacing existing doors with bifold doors doesn't usually require planning permission. However, if you're creating a new opening, carrying out structural alterations or your home is listed or in a conservation area, additional permissions may be needed. Always check with your local authority before work begins.
