Introduction
Bifold doors are a popular choice for UK homes—and it’s easy to see why. You can use them in a kitchen extension, a garden room, or any open-plan space.
But let’s face it—cost matters.
So, how much do bifold doors cost? And what affects the final bifold door cost from one project to the next?
In this guide, we’ll explain it all. You’ll get real price examples, product comparisons, installation tips, and expert advice—so you know exactly what to expect. And how to get the best value with GFD Homes.

Bifold Doors Cost: Why Bifold Doors Are a Smart Investment
Bifold doors offer one of the most effective ways to:
- Create a seamless indoor-outdoor connection
- Maximise natural light and garden views
- Add visual impact and architectural interest
- Boost the perceived value and flow of your home
Unlike sliding or French doors, bifolds fold and stack neatly to the side, leaving a wide, unobstructed opening—ideal for open-plan spaces or alfresco living areas.
“We believe in products that improve your home and lifestyle. That’s why we only stock bifold doors that blend performance, beauty and affordability.”

What Affects Bifold Door Cost in 2025?
The cost of bifold doors can vary significantly depending on:
1. Number of Panels
More panels mean higher costs. A 3-panel door is cheaper than a 5- or 6-panel setup.
2. Opening Size
Larger openings require stronger systems and often bespoke measurements, which affect the price. For example:
- A standard 3.0m wide x 2.1m high set may be far cheaper than a 5.4m x 2.4m installation.
3. Glazing Type
- Double glazing is standard.
- Triple glazing, solar control, or laminated safety glass adds cost.
4. Colour and Finish
- Standard RAL finishes (white, grey, black) are included.
- Dual colour, textured, or anodised finishes incur an extra charge.
5. Threshold Options
- Rebated thresholds offer better weatherproofing.
- Low/flush thresholds are better for accessibility and indoor-outdoor flow.
6. Hardware & Accessories
Premium handles, integrated blinds, trickle vents, and locking systems can all increase the overall cost.

Bifold Doors: Cost of Installation

- Complexity of the opening
- Existing vs new openings
- Structural support requirements
Always get at least two quotes and confirm:
- If structural calculations (e.g., lintels, steels) are needed
- Whether removal of old doors is included

“The cheapest quote isn’t always best. Always check credentials and references for door installers.”
