If your front door is looking tired, feeling draughty, or you simply want to upgrade your home’s security, a composite door is the ultimate replacement.
However, when Leicestershire homeowners start researching prices online, things can get confusing very quickly. You might see national companies advertising doors for £500, while others quote well over £3,000 for what looks like the exact same product.
At Eco Windows Ltd, we believe in honest, transparent quoting without the high-pressure sales tactics. So, how much does a high-quality, fully fitted composite door actually cost in 2026?
The Average Cost of a Fully Fitted Composite Door
For a high-quality, fully installed composite door from a reputable brand like DoorCo, most homeowners in Leicestershire should expect to invest somewhere between £1,500 and £2,500.
If a quote comes in significantly lower than £1,500, it usually means corners are being cut—either with a cheap foam-filled core, low-grade locks, or a poor-quality installation. If a quote is pushing £4,000 for a standard door, you are likely paying for a national company’s massive advertising budget rather than the door itself.
What Actually Affects the Price of Your New Door?
Two houses on the same street could order a new front door and receive entirely different quotes. Here are the five main factors that will determine the final cost of your installation:
1. The Door Style and Glazing A solid composite door without any glass panels is typically the most cost-effective option. As soon as you add decorative, frosted, or leaded glass panels, the manufacturing complexity increases, which naturally adds to the cost.
2. Hardware and Security Upgrades Standard lever handles and letterboxes keep costs down. Upgrading to premium architectural hardware, such as 1200mm brushed steel pull handles, heritage monkey-tail handles, or advanced smart-locking systems, will increase the final price.
3. Bespoke Colours vs Standard Colours Most manufacturers offer a range of standard colours (like White, Black, Anthracite Grey, or Chartwell Green) included in the base price. If you want a bespoke RAL colour to perfectly match your existing windows or garage door, this custom spraying process will carry a premium.
4. Side Panels and Top Lights If your hallway entrance is wider than a standard door frame, you will need glazed side panels (sidelights) or a glass panel above the door (a top light). Because these require extra materials and custom manufacturing, they will significantly impact your final quote.
5. Frame Condition and Structural Work A straightforward “rip out and replace” is the cheapest installation method. However, if your existing timber frame has rotted or the brickwork needs repairing before the new door can be fitted, this extra labour and material will need to be factored into the cost.
