The short answer
A composite door in the UK typically costs around £700 to £2,000 supply-only, and roughly £900 to £3,000 fitted, with a standard front door commonly landing between £1,100 and £1,800 installed. The door slab itself is the largest single line, but the final figure depends heavily on size, glazing, colour, hardware and whether the frame is being replaced. Labour to fit a like-for-like door is usually a few hundred pounds, while structural changes or a new frame add more. Because installers package these elements differently, two quotes can describe quite different scopes, so the headline price alone is rarely enough to compare on.
Composite door pricing spans a wide band because spec, size and fitting scope all move the figure; understanding the lines behind the total makes a quote easier to judge.

Typical UK price ranges
Composite doors sit between cheaper uPVC and pricier timber, and the quoted figure depends on whether you are buying the door alone or a fully fitted job. The table below shows indicative 2026 UK ranges for guidance rather than a fixed quote, because every opening and specification differs.
Supply-only prices cover the made-to-measure door and frame leaving the factory. Fitted prices add the installer's labour, removal of the old door, sealing and trims. The lower end reflects a standard-size slab in a common colour with minimal glazing; the upper end reflects larger doors, decorative glass, side panels or premium hardware.
| Option | Typical cost | Notes |
|---|---|---|
| Supply-only door set | £700–£2,000 | Door and frame, made to measure |
| Fitting labour only | £200–£600 | Like-for-like, existing opening |
| Fitted standard front door | £1,100–£1,800 | Door, frame, labour, trims |
| Fitted premium / glazed | £2,000–£3,000+ | Glass, colour, side panels, hardware |

What pushes a composite door price up
Several factors explain why one composite door costs hundreds of pounds more than another of the same basic type:
- Size and configuration — non-standard widths, double doors and openings with side panels need more material and a larger frame.
- Glazing — decorative or double-glazed panels, obscured glass and bevelled designs cost more than a solid slab.
- Colour and finish — popular standard colours are lowest-cost; bespoke shades, dual colours and woodgrain finishes add to the bill.
- Hardware and security — upgraded multipoint locks, handles, letterplates, knockers and accredited security can lift the price.
- Frame and threshold — replacing the whole frame, or fitting a low or part-M accessible threshold, adds cost over reusing existing fixings.
Brand and core construction matter too. A solid-timber or solid-core composite slab generally costs more than a foam-filled GRP door, and recognised brands often carry a premium over unbranded equivalents.
Supply-only versus fitted
Buying supply-only saves the installer's labour margin but shifts responsibility for measuring, fitting and compliance onto you or a separate tradesperson. If a measurement is wrong, the made-to-measure door may not be returnable, so accuracy matters. A fitted quote bundles the door, labour, removal of the old door and the sealing and trim work into one accountable package, which most homeowners find simpler.
When comparing, check whether the fitted figure includes removal and disposal of the old door, a new frame or just the slab, and whether VAT is shown. Replacement external doors must meet thermal and safety glazing standards, and using an installer registered with FENSA or an equivalent competent person scheme means the glazing work can be self-certified rather than needing a separate building control application.
How to budget and compare fairly
Treat the door specification and the fitting as two separate parts of your budget. Decide the size, colour, glazing and hardware you want first, then get fitted quotes for that exact specification so each installer is pricing the same thing. A quote that itemises the door, the labour, removal and any frame work is far easier to judge than a single lump sum.
Build in a small contingency for surprises found once the old door is removed, such as a frame that has rotted into the surrounding brickwork or a threshold that needs levelling. Ask about the product warranty on the slab and glass, the workmanship guarantee on the fitting, and how long the installer has been trading. The lowest number is not always the best value: a fuller scope, a recognised door brand and a registered fitter can cost a little more but reduce the risk of problems later. For most homeowners a clear, itemised fitted quote for a defined specification gives the most reliable picture of the true cost, and makes it straightforward to compare one installer against another on a like-for-like basis rather than on the headline price alone.
Frequently asked questions
Is a composite door cheaper than a uPVC door?
No. uPVC doors are generally the lowest-cost option, with composite doors costing more for their solid feel, durability and security. Timber doors usually cost the most. The gap reflects the heavier, multi-layer construction of a composite slab.
How long does a composite door last?
A good-quality composite door commonly lasts around twenty to thirty years or more with basic maintenance. The slab resists warping, fading and weathering better than timber, though hinges, seals and locks may need attention over time.
Does the price include the frame?
Not always. Some quotes are for the door slab only and reuse the existing frame, while others include a new frame. Always confirm, because a new frame adds cost and a slab fitted to an old frame may not seal as well.
