The base price for a standard single composite door, fitted, is usually £800 to £1,200 (Checkatrade, 2026). Larger sizes, double doors, or French doors push the range significantly higher, often to £1,500 to £2,500 or more. The final cost depends on door size, glazing type, colour and finish, hardware grade, and installation complexity.
The main cost drivers are door size, glazing, and security rating
Standard single doors are approximately 900mm wide by 2100mm high. Wider or taller doors require more material and add £200 to £500 to the price. The glazing choice is a major factor. Double-glazed units are standard, but triple-glazing adds a further £150 to £300 (Glass and Glazing Federation, 2026).
Security-rated doors, such as those meeting PAS 24:2022 or carrying Secured by Design certification, carry a premium of £100 to £250. This is often required by home insurance policies, so it is not an optional extra for many homeowners. The grade of hardware, hinges, letterbox, and cylinder lock, also affects the total. A high-security cylinder from a reputable brand can add £50 to £100.
Installation and removal of the old door add £150 to £350 to the total
Fitting costs vary by region. London and the South East are typically £50 to £100 more than the UK average (Checkatrade, 2026). Removal and disposal of your old door is usually included in the fitting price, but can be charged extra if the door is non-standard, such as a very old or heavy timber door.
Installation complexity matters. A straightforward replacement in an existing opening is cheapest. If the frame needs adjustment, the brickwork requires repair, or the opening is out of square, expect additional charges of £50 to £150. Always confirm what is included in the fitting quote before agreeing.

A standard, single composite door fitted costs between £900 and £1,500 in most UK regions
This is the direct answer most homeowners are looking for. The price includes the door slab, frame, hinges, letterbox, cylinder lock, and installation. Variations depend on your location, supplier, and whether you choose a bespoke colour or glass design (Checkatrade, 2026).
If you live in the North of England, Scotland, or Wales, prices tend to be at the lower end of this range. In London and the South East, expect the higher end. A standard door in a neutral colour with clear double glazing and a basic security lock will be at the bottom of the range. Add a designer colour, decorative glass, or a premium lock, and the price will rise towards £1,500.
You need a FENSA-registered or MCS-certified installer for compliance and warranty validity
In England and Wales, replacement doors must comply with Building Regulations. A FENSA-registered installer can self-certify the work, meaning you do not need a separate building control application (FENSA, 2026). If the door is part of a wider energy-efficiency upgrade, such as a grant or finance scheme, MCS certification may be required (MCS, 2026).
Always check the installer is on the FENSA or MCS register before paying a deposit. Ask for a quote that includes certification. Without it, you may invalidate your home insurance or face problems when selling the property.
Local prices vary by up to 20% between suppliers, so get three quotes
Prices from local installers can vary significantly. A 20% difference on a £1,000 door is £200 (Which?, 2026). National chains such as Everest or Safestyle tend to be pricier than local FENSA-registered firms, but may offer longer warranties or more flexible payment terms.
To get the best price, request three quotes for the same specification. Compare them line-by-line, checking what is included for fitting, removal, and VAT. Ask neighbours for recommendations and read online reviews on TrustMark or Checkatrade. A lower price is not always better if the installer has poor reviews or no certification.
How to compare quotes for home improvements
Energy performance, a composite door can achieve a U-value of 1.2–1.8 W/m²K, saving up to £50 per year on heating
A U-value measures how much heat passes through a material. Lower numbers mean better insulation. Composite doors with a foam core and thermal break typically achieve U-values between 1.2 and 1.8 W/m²K. This compares favourably to an uninsulated solid wood door, which can have a U-value of around 3.0 W/m²K (Energy Saving Trust, 2026).
The Energy Saving Trust estimates that a new, well-fitted composite door can save a typical semi-detached home up to £50 per year on heating bills. This saving comes from reduced draughts and better insulation. Over the door’s lifespan of 20–30 years, the energy savings can offset part of the upfront cost.
