UK cost guide
Bifold doors fold back to open up most of a wall, so the price rises with every extra panel and with the frame material. The figures here assume the opening already exists. Creating or widening one is a structural job with its own costs.
Typical budget
£2,000 to £7,500+
Supply and fit into an existing opening. Creating or widening an opening is priced separately.
Typical UK bifold door budgets by project size.
| Budget band | Typical cost | What it usually covers |
|---|---|---|
| Starter | £2,000-£3,500 | a three-panel uPVC or timber set fitted into an existing opening. |
| Mid-range | £3,500-£5,500 | a four-panel set, or a three-panel aluminium set. |
| Premium | £5,500-£7,500+ | a five-panel aluminium set for a 3.6-5m opening. |
Supply and fit into an existing opening. Creating or widening an opening is priced separately.

Sources
Number of panels and the width of the opening
Frame material: uPVC, timber or aluminium, plus colour, threshold and glazing upgrades
Structural work: a new or wider opening needs a lintel or steel, an engineer and building control
Ask each shortlisted company to confirm the same scope and timeline. Avoid comparing a supply-only price with a fitted quote; also avoid ordering doors before the opening has been measured after any structural work and assuming a low threshold or integral blinds are included as standard.
