What Makes a Composite Door?
A composite door combines a solid timber core, a uPVC or GRP outer skin, and steel reinforcement, bonded together to create a door that outperforms traditional wooden or uPVC options on security, insulation, and longevity. They do not warp, rot, or require repainting, and they come in a wide range of styles and colours to suit any property.
Security Standards to Look For
Look for composite doors that meet the Secured by Design specification — the police-preferred standard. Key features include a multi-point locking system, anti-snap, anti-drill, and anti-pick lock cylinder, and reinforced hinges. A quality composite door with the right cylinder is among the most secure residential door options available in the UK.

Getting the Right Fit
Composite doors are made to order based on precise measurements. A professional installer will measure your existing opening carefully, advise on whether the frame needs replacing, and ensure the door is fitted to a standard that maintains its security and thermal performance. Always use an installer who will visit your property to measure before providing a final price.
