If you are asking “how much are composite doors with glass”, the direct answer is £1,200 to £2,000 supplied and fitted for a standard single door, with larger or more complex designs reaching £3,000. This guide breaks down the costs by glass specification, door size, and what you need to check before buying.
Composite door prices range from £1,200 to £2,000 supplied and fitted
Standard sizes, such as 838mm wide by 1981mm high, with a single glass panel start at around £1,200. Larger or non-standard sizes, like 1800mm wide French doors with glass, reach £2,000–£3,000. Installation costs are typically included in the quote, but separate fitting fees range from £150 to £400 if quoted separately (Which? door installation report, 2026).
Most major suppliers include fitting in their package price, but always confirm this before signing. If you are buying the door only, budget an extra £200–£400 for a certified installer.
The glass type and size are the biggest cost drivers
Double-glazed glass panels with a U-value of 1.4 W/m²K or better are standard in composite doors. Upgrading to triple glazing adds £150–£300. Self-cleaning glass adds £100–£200, while decorative etched or leaded glass adds £75–£250 (Glass and Glazing Federation technical bulletin, 2026).
Larger glass panels, such as full-height 2.4m doors, increase the base cost by 20–30% due to structural reinforcement needs. The glass itself is the most expensive single component, so choosing a smaller decorative panel rather than a full-height glazed section can save £300–£500.

You must check the installer is MCS-certified or Gas Safe registered for any glazed composite door
All glazed composite doors installed in the UK must comply with Building Regulations Part L (thermal efficiency) and Part N (safety glazing). For doors with glass panels, the installer should be MCS-certified (Microgeneration Certification Scheme) if the door is part of an energy-efficiency upgrade claim, or FENSA-registered for general compliance (FENSA website, 2026). Gas Safe Register is only required if the door is installed near a gas appliance or flue; otherwise, MCS or FENSA is sufficient.
To verify an installer, search the MCS register (mcscertified.com) or FENSA database (fensa.org.uk) by postcode or company name. Always request a certificate of compliance after installation.
How to choose a FENSA-registered door installer
Grants and schemes can reduce the cost of a composite door with glass
The Great British Insulation Scheme (GBIS) offers grants of up to £1,000 for energy-efficient doors, including composite doors with double glazing, for eligible low-income households (GOV.UK GBIS page, 2026). The Home Upgrade Grant (HUG2) provides up to £10,000 for whole-home improvements, but composite doors are only covered if the home has no central heating or a poor EPC rating (DESNZ HUG2 guidance, 2026).
Eligibility is based on household income (under £31,000) and EPC rating (E, F, or G). Check your eligibility via the Simple Energy Advice service (gov.uk/energy-grants).
Everything you need to know about the Great British Insulation Scheme
If you do not qualify for grants, paying for a composite door with glass out of pocket still offers long-term energy savings. A well-fitted composite door with double glazing can reduce heat loss by up to 30% compared to an old timber or uPVC door, cutting annual heating bills by £100–£200 depending on your home size and tariff.
