How much do bifold doors cost in the UK?
Bifold doors cost £4,000 on average in the UK. Most jobs fall between £2,000 and £9,000 supplied and fitted. Size and material: 3-panel uPVC £2,000 to £3,500; 3-4 panel aluminium £3,500 to £6,000; 5+ panel aluminium £5,500 to £9,000. Prices reviewed June 2026.
Bifold doors, also called folding doors, are priced by the overall size and the frame material. uPVC is the budget choice, aluminium costs more but is slimmer and stronger, and widening the opening adds the most.

Bifold doors cost breakdown
Typical bifold doors costs, by option:
| Size and material | Typical UK cost | Typical life |
|---|---|---|
| 3-panel uPVC | £2,000 to £3,500 | 20 to 30 years |
| 3-4 panel aluminium | £3,500 to £6,000 | 25 to 45 years |

| + Widen the opening (structural) | add £1,500 to £4,000 |
What's included in the price?
Typical bifold doors prices include:
- The bifold door set and frame
- Removal of the old opening and making good
- Fitting, sealing and certification
- Standard double glazing
What changes the price?
The things that move bifold doors prices most:
Overall width and the number of panels
Frame material: uPVC is cheapest, aluminium costs more and is slimmer
Glass spec and any colour or finish
Structural work if the opening is being widened
How the price is built up
Most of the price is the door set itself, the frame, the running gear and the glazed panels, plus a day or two of fitting. A three panel uPVC set is the cheapest route and sits near the £2,000 floor, because uPVC costs less than aluminium and a narrower opening needs fewer panels. Moving up to aluminium lifts the frame cost, and going to a five panel or wider run pushes towards £9,000. Glass upgrades, a coloured or dual finish and better running gear each add to the total. Widening the opening is a separate structural job that adds £1,500 to £4,000. The door set and glazing are the bigger share on most jobs, usually around 60 to 70 percent of the total, with the day or two of fitting labour making up the rest.
Ways to keep the cost down
- A three panel uPVC set is the cheapest route at £2,000 to £3,500, so if you do not need the slim sightlines of aluminium, uPVC keeps you near the floor.
- Keep the existing structural opening. Widening it is charged separately at £1,500 to £4,000, so working to the size you already have avoids the biggest single add-on.
- Standard white or a single colour costs less than a dual or non-standard finish, so a plain finish trims the frame and glass cost.
- Get two or three quotes before you commit, and if you are in a higher-cost area such as London or the South East, it is worth asking fitters based a little further out.

Common questions
How much are bifold doors fitted?
A typical 3-panel uPVC set runs about £2,000 to £3,500 supplied and fitted, while a wider aluminium set is roughly £3,500 to £6,000 and more for 5 or more panels.
Are aluminium bifolds worth the extra over uPVC?
Aluminium has slimmer sightlines, more glass and better strength for wide openings, which is why most larger bifolds are aluminium. uPVC is cheaper and fine for smaller openings.
What are the disadvantages of bifold doors?
The folded stack takes up part of the opening, the tracks need keeping clean to run smoothly, and the many frames mean more visual interruption than a big slider. Heat loss is also higher than a solid wall, so a north-facing set can make a room cooler. Modern multi-point locks have largely answered the old security worry.
How much does structural work add to a bifold installation?
If you are widening the opening rather than swapping like for like, budget £1,500 to £4,000 on top of the doors for the steel lintel, the structural work and building control sign-off. That is often the difference between the £2,000 to £3,500 uPVC end of the market and a project total nearer £6,000 to £9,000.
Do bifold doors add value to a home?
Not in a way that pays for itself pound for pound. A supplied and fitted bifold run costs £2,000 to £8,000, and while opening a kitchen or living room to the garden makes a room feel larger and lighter and can help a sale, few estate agents will value the doors at more than they cost. Treat them as something you buy to enjoy while you live there, rather than an investment that returns the outlay.
How much does each extra panel add to the price?
There is no fixed price per panel, but panel count is one of the main things that moves the total. A three panel uPVC set runs £2,000 to £3,500, a three or four panel aluminium set £3,500 to £6,000, and a five panel or wider aluminium run £5,500 to £9,000. More panels means a wider opening, more glass and more running gear, so each step up carries frame, glazing and hardware cost, not just one more leaf.
Are internal bifold doors cheaper than these external ones?
Yes, by a wide margin. The £2,000 to £8,000 on this page is for external, glazed, weatherproof bifold sets that are supplied and fitted. Internal bifolds used as room dividers are a much simpler product with no weather sealing and no structural opening, so they cost a fraction of that and are often bought as single leaves and hung by a joiner. If you are pricing an internal divider, do not use these external figures as a guide.
How long do bifold doors last?
Aluminium frames are the long-lived option at 25 to 45 years and uPVC at 20 to 30, though those numbers come from door sellers so the top of each range is a best case rather than an expectation. The frame is rarely what ends a set of bifolds anyway. Two other things wear on their own clock: the running gear, where rollers, hinges and the bottom track carry a heavy door across a wide opening, and the sealed glass units, usually put at 20 to 25 years before a seal fails and the pane mists up. Both are serviceable. A new set of rollers or one replacement glass unit is a repair, not a reason to buy another £2,000 to £8,000 of doors, which is worth knowing if an installer quotes you for the whole set.
Can I fit bifold doors myself?
You can, but it is one of the harder DIY jobs and most people should not. Fitting labour is only about 30 to 40 percent of the total, since the door set and glazing are 60 to 70 percent, so the saving is modest against the risk. Getting the aperture square, the frame dead level and the seals right is fiddly, and a poorly hung run drops, drafts and leaks. If any structural opening is involved, that part needs proper sign-off.
