How much does a composite front door cost in the UK? (2026)
Verified UK composite front door prices for 2026, supplied and fitted, by brand tier and specification, plus the anti-snap lock standard and FENSA registration a fair quote should include.
A composite front door in the UK in 2026 costs £900 to £2,500 supplied and fitted, with most homeowners paying £1,200 to £1,800. The door is one of the most visible upgrades a house gets, but the part that matters most is out of sight: the lock cylinder, where a cheap door can quietly skip the anti-snap protection that keeps it secure.

How to read this guide#
Two kinds of figures appear below:
- Headline price ranges (by tier and spec): cross-referenced against UK 2026 door cost guides. Source listed at the bottom.
- Practical guidance (supply vs fit, security, registration): standard UK practice and safety standards, for context rather than figure-by-figure verification.
Headline ranges (verified)#
Composite front door, supplied and fitted, UK 2026:
| Tier | Typical cost |
|---|---|
| Budget GRP door | £900 – £1,200 |
| Mid-range brand | £1,200 – £1,800 |
| Premium / aluminium-skinned | £1,800 – £2,500 |
| With sidelights, triple glazing, upgrades | £2,500 – £4,000 |
Fitting labour is roughly £300-£700 of the total. Triple glazing adds £150-£300, and sidelights or a fanlight add more. The slab itself ranges from a 44mm GRP door to a 70mm aluminium-skinned one.
Practical guidance (industry standard)#
Supply only or supply and fit#
A "composite door" price can mean the door and frame alone, or the whole job including removing the old door, fitting, sealing, and making good. Fitting adds £300-£700, plus any repair to the opening. Always confirm which the quote is, because a supply-only figure looks far cheaper than a fitted one.
The lock is where security is won or lost#
A multipoint locking mechanism is standard on composite doors, but the cylinder is the weak point attackers target. Lock snapping (breaking the cylinder to force the door) is the most common method, so the cylinder must be anti-snap:
- Look for a TS007 3-star cylinder, or a 1-star cylinder paired with a 2-star security handle (which also totals three stars).
- Brands such as Brisant Ultion and Avocet ABS make 3-star anti-snap cylinders.
A 3-star anti-snap cylinder should be the minimum on a new front door, and the quote should name the cylinder, not just say "multipoint lock". A door sold on its looks with a basic cylinder is the red flag here.
Brands and what you are paying for#
The main UK composite door brands span budget to premium: budget GRP doors (for example Door-Stop), mid-range brands (Solidor, Endurance), and premium brands (Rockdoor, Apeer). Higher tiers add a thicker slab, an aluminium skin, better weather sealing, and stronger hardware. The brand and slab should be on the quote, the same way a kitchen quote should name the cabinet range. See how to read a builder's quote.
Registration matters for resale#
Replacing an external door is notifiable under Building Regulations. A FENSA or CERTASS registered installer self-certifies the work and issues a certificate you will need when you sell. If your fitter is not registered, the job must go through Building Control instead. A quote that says nothing about registration has left out a step a buyer's solicitor will ask about.
What affects the price#
- Brand and tier. Budget GRP to premium aluminium-skinned.
- Glazing. Double or triple, plain or decorative; sidelights and fanlights add cost.
- Hardware. Upgraded anti-snap cylinders, smart locks, and quality handles.
- The opening. A non-standard size or a damaged frame adds remedial work.
What is often excluded#
- Fitting and making good, if the price is supply only.
- A FENSA/CERTASS certificate, where an unregistered fitter is used.
- Sidelights, fanlights, and decorative glass, sometimes priced separately.
- Upgraded anti-snap cylinder, if only a basic lock is included.
- Removal and disposal of the old door.
For the related glazing work, see the new windows and double glazing and bifold doors guides.
Red flags in a composite door quote#
- "Multipoint lock" with no cylinder standard named. Insist on TS007 3-star anti-snap.
- Supply-only price presented as the whole job.
- No FENSA or CERTASS registration mentioned.
- No brand or slab thickness, so the door cannot be compared.
- A fitted price well below £900, which usually means supply only or a basic cylinder.

Frequently asked questions
- How much does a composite front door cost in the UK in 2026?
- Supplied and fitted, a composite front door typically costs £900 to £2,500, with most homeowners paying £1,200 to £1,800. Budget GRP doors start around £1,100, mid-range brands £1,200-£1,300, and premium doors from £1,500. Aluminium-skinned models with sidelights and triple glazing can reach £3,500-£4,000.
- Is the quote supply only or supply and fit?
- Check carefully, because the gap is large. The door slab and frame alone are one price; fitting adds roughly £300-£700 for labour, plus any work to make good the opening. A low "composite door" figure is often supply only. A fair quote states whether removal of the old door, fitting, and making good are included.
- What lock and security should a composite door have?
- A multipoint lock is standard, but the cylinder is what matters. Look for a TS007 3-star (or a 1-star cylinder plus a 2-star handle) anti-snap cylinder, which resists lock snapping, the most common way composite doors are forced. A 3-star anti-snap cylinder should be the minimum on any new front door, and the quote should name it.
- Does a new front door need to be registered?
- Yes. Replacing an external door is notifiable under Building Regulations for thermal and safety performance. A FENSA or CERTASS registered installer self-certifies the work and you get a certificate, which you will need when you sell. If the installer is not registered, the work has to be signed off by Building Control instead.
- What makes one composite door more expensive than another?
- Brand, slab thickness, skin, glazing, and hardware. A 44mm GRP door with minimal glazing sits at the bottom of the range; a 70mm door with an aluminium skin, triple glazing, sidelights, and upgraded anti-snap locks sits at the top. A fair quote names the brand, the slab, the glazing, and the lock so you can compare like-for-like.
