The short answer
A composite door fitted in the UK typically costs between £900 and £3,000, with a standard front door commonly installed for around £1,100 to £1,800. That figure combines the made-to-measure door set, fitting labour of roughly £200 to £600, removal of the old door, and sealing and trims. The price climbs for larger doors, decorative glazing, side panels, premium hardware or a full frame replacement. A fitted quote is simpler than buying supply-only because one company is accountable for the door, the fit and the glazing compliance, but the exact scope varies, so it pays to confirm what is included before comparing prices.
A fitted price bundles the door, labour and finishing into one accountable package, but the included scope varies enough that two quotes can mean quite different work.

What a fitted composite door costs
A fitted price brings together the door set, the labour and the finishing work into one figure. The table shows indicative 2026 UK ranges for a like-for-like replacement into an existing opening, where the frame is replaced but no structural change is needed.
The door set is the largest line, with labour the next biggest. Removal covers taking out and disposing of the old door, and making good tidies the reveals and seals the new frame. The total is fairly predictable for a same-size replacement because the opening already exists, so the work is mostly removal, fitting, sealing and trimming.
| Element | Typical cost | Notes |
|---|---|---|
| Door set (standard) | £800–£1,300 | Made to measure, frame included |
| Fitting labour | £200–£600 | One fitter, part to full day |
| Removal & disposal | £50–£150 | Old door taken away |
| Sealing, trims, making good | £50–£200 | Reveals and weather seal |
| Total fitted (typical) | £1,100–£1,800 | Existing opening, like for like |

What can be left out of a low quote
A cheap headline price sometimes excludes items that turn out to be necessary. Common exclusions to check for include:
- A new frame — some quotes fit the slab into the existing frame, which may not seal as well or last as long.
- Removal and disposal of the old door, which can be billed separately.
- Decorative glazing or upgraded hardware shown in the brochure but priced as extras.
- Threshold work where the floor level or sill needs adjusting.
- VAT, which adds twenty per cent if quoted on the net figure.
Asking each installer to itemise the door, labour, frame, removal and any extras lets you compare like for like, so a fuller quote is not unfairly judged against a stripped-back one.
Self-certification and accountability
Replacement external doors must meet thermal and safety glazing standards under the Building Regulations. An installer registered with FENSA or an equivalent competent person scheme can self-certify the glazing work, which saves a separate building control application and gives you a registration certificate for your records. This certificate is useful when you sell the property, as a buyer's solicitor may ask for it.
A fitted quote also means one company is responsible if something goes wrong. If a supply-only door leaks or sticks, it can be unclear whether the fault lies with the product or the fitting; with a fitted job, the installer is accountable for both.
How to budget and compare
Decide the specification you want first, then get fitted quotes for that exact door so each installer prices the same thing. Confirm whether the figure includes a new frame, removal of the old door, sealing and trims, and VAT. Ask how long the job will take, when the door can be supplied, and what warranty covers the slab, the glass and the fitting workmanship.
For a straightforward same-size replacement, a single fitter usually completes the job in a few hours to a day, and the cost is dependable. Where the opening is changing size, or the threshold needs levelling, factor in extra time and cost, and treat that work as a separate line. A clear, itemised fitted quote that names the door, the labour, the frame and any extras is the easiest to budget against and to compare across installers. The lowest figure is not always the best value once you account for the door brand, the scope included and whether the installer is registered, so weigh the full package rather than the headline price alone. Keeping the registration certificate and warranties on file protects you later if a fault appears or you come to sell.
Frequently asked questions
How long does it take to fit a composite door?
A like-for-like replacement into an existing opening usually takes a few hours to a day for one fitter. Jobs involving a new or resized opening, a threshold change, or making good can take longer.
Is fitting included in the door price?
Not unless the quote says so. Some prices are supply-only for the door alone, while a fitted or installed quote adds labour, removal and sealing. Always check whether the figure is supply-only or fully fitted before comparing.
Do I need building regulations to replace a front door?
Replacement external doors must meet thermal and safety glazing standards. An installer registered with FENSA or a similar scheme can self-certify this, avoiding a separate building control application. Keep the certificate for when you sell.
