Composite Front Door Cost UK: Solidor, Rockdoor, and Apeer Pricing
A high-performance composite front door typically costs between £1,200 and £3,000 installed. While the price range is broad, the delta is usually driven by the complexity of the glazing, the quality of the multi-point locking system, and the brand’s warranty.

Premium Brand Breakdown: Apeer, Rockdoor, and Endurance
When shopping for a composite door, you are essentially paying for the “skin” technology and the core stability.
Apeer: Specializes in A++ energy-rated doors. Their focus is on maximum thermal efficiency, making them the primary choice for homeowners prioritizing heat retention. If you’re upgrading an EPC rating to move out of a “Band E” property, Apeer’s thermal specs are industry-leading.
Rockdoor: Positions itself as a security system first and a door second. With a network of 200+ trusted installers and a massive 30-year track record, Rockdoor is the “safe bet” for those who want a proven system with a robust installer network.
Endurance: Known for “CoolSkin” technology and a 48mm solid laminated veneer core. Endurance doors are engineered for strength, featuring ABS Master Locking Cylinders and a £2,000 security guarantee. This makes them the primary choice for high-crime areas or high-value homes where security is the non-negotiable priority.
What most guides miss: The “Side-Panel” Trap
Most composite door quotes provide a price for the door leaf only. However, the cost can double if you have a side-panel or a top-light.
A standard composite door might be £1,400, but adding a matching composite side-panel with double glazing can add another £600-£1,000 to the bill. Furthermore, if your existing door frame is rotten, you cannot simply “swap the door”—you will need a full frame replacement, which adds significant labor costs.
For those tackling a full-home retrofit, your front door is the biggest “thermal hole” in your property. Upgrading to a composite door as part of a strategy involving Passivhaus windows spec and IWantSolar PV integration can practically eliminate the need for hallway heating. If your home is currently Unmortgageable due to structural decay around the entrance, a full composite system replacement is the fastest way to provide the structural integrity lenders require.
Summary: Which Door Should You Buy?
- Maximum Energy Efficiency: Apeer (A++ rated).
- Maximum Security & Durability: Endurance (CoolSkin + ABS locks).
- Maximum Trust & Installation Support: Rockdoor (huge installer network).
- Budget-Conscious: High-quality uPVC.
