How Much are Bifold Doors in the UK?

In the UK, bifold door prices usually range from £1,760 to £7,000, depending on the material and the number of panels. Smaller uPVC bi-fold door sets are cheaper, while aluminium door sets are the most expensive due to their durability and modern design. Most bifold doors require professional installation, which typically adds £600-£1,000 to the total cost. Here is a breakdown of bifold door costs by panel count and material.

Note: Prices shown are for standard 3–5-panel doors, supply-only. Final costs change based on glazing, hardware, finish, and installation.

Cost Breakdown of Bifold Doors by Material

The material you choose has the biggest impact on price. Below are the costs and benefits for each bifold door material.

uPVC Bifold Doors

uPVC bifold doors are the most affordable option, costing between £700 and £4,000 for a standard 3-5 panel set. These doors are made from a strong, rot-resistant plastic that doesn't warp or require painting. They work well in modern homes and are available in white or woodgrain finishes. uPVC doors provide good energy efficiency, keeping your home warm in winter and cool in summer.

Pros

• They resist rain, wind, and UV damage without fading or warping over time.
• Easy to maintain, they only need a quick clean with soapy water to stay looking new.

Cons

• Colour options are limited mostly to white and basic woodgrain finishes.
• Less durable than aluminium, so they are not ideal for very large openings.

Aluminium Bifold Doors

Aluminium bifold doors are a popular mid-to-premium option, with prices ranging from £1,500 to £6,200 for a standard 3–5 panel set. They are made from strong, lightweight metal that allows slim frames and larger glass panels. This makes rooms feel brighter and more open. Aluminium doors suit modern homes and perform well in the UK’s changing weather.

Pros

• Slim frames maximise glass space, making rooms feel brighter and more open.
• Strong structure supports wider openings without sagging over time.

Cons

• Higher upfront cost compared to uPVC, especially for wider or taller openings.
• Poor insulation unless thermal breaks are included, which are expensive.

Timber Bifold Doors

Timber bifold doors usually cost between £2,000 and £6,000 or more, depending on the wood type and finish. They offer a natural, warm appearance that suits traditional and period homes. Timber frames can be customised with stains or paint colours to match interiors. While visually appealing, timber doors need more care to protect them from moisture and weather changes.

Pros

• Natural wood look adds character and suits classic or period-style homes.
• Can be painted or stained to match interior and exterior design changes.

Cons

• Requires regular sealing or repainting to prevent weather damage.
• It can swell or shrink slightly with moisture if not properly maintained.

Composite Bifold Doors

Composite bifold doors are a premium option, typically priced from £3,500 to £7,900 or more. They combine materials such as timber, aluminium, and uPVC to enhance strength and insulation. These doors offer a high-end appearance with better durability than single-material frames. Composite bifolds are often chosen for luxury homes where performance and looks are equally important.

Pros

• Combines strength and insulation for long-term performance and comfort.
• Offers premium finishes without the heavy maintenance of solid timber.

Cons

• Higher purchase cost than single-material bifold doors.
• Fewer suppliers available, which can limit design and size options.

Factors Affecting Bifold Door Prices

The total cost of bifold doors depends on multiple factors that affect performance, appearance, and fit, which together determine the final price you pay.

Material

The type of door you choose has a big impact on the final price about 40-60% of your total cost. Some options cost less upfront but offer thicker frames, while others cost more for slimmer designs and longer life. Premium options also handle weather better and suit larger openings, which naturally increases the overall cost of the door.

Size of Panels

Larger panels cost more because they use more glass and need stronger frames. Wide openings also require heavier hardware to support the weight safely. As panel size increases, both manufacturing and fitting become more complex, thereby increasing the total price of the bifold door set.

Number of Panels

Doors with more panels usually cost more than doors with fewer panels. Each extra panel adds more glass, hinges, rollers, and fitting time. While more panels create wider openings and better flexibility, they also increase material and labour costs, which affects the final price you pay.

Glazing Options

The type of glass used can significantly affect the price. Standard glazing costs less, while energy-efficient or thicker glass costs more. Better glazing improves insulation, reduces noise, and helps lower energy bills, but it adds to the overall cost of the bifold doors.

Installation Complexity

Simple installations cost less, while complex fitting raises the price. If the opening needs structural work, new supports, or uneven surfaces to be fixed, installers need more time and labour. Difficult access or custom fitting also increases installation costs compared to straightforward replacements.

Customisation

Personal touches can increase the cost of bifold doors. Special colours, premium handles, built-in blinds, or unique finishes add to the price. While custom features improve style and better match your home, they usually increase both manufacturing time and overall cost.

Key Takeaways

Bifold door prices vary based on size, material, glazing, and design choices. Understanding these factors helps you plan your budget better and avoid surprises later. Carefully comparing options ensures you choose doors that suit both your home and your long-term needs.
