The short answer
The composite door brands you'll most often see quoted in the UK include Solidor, Rockdoor, Endurance and the Composite Door Co, among others. They differ mainly in construction and core, finish range and price: some use a solid timber core, others a foam-filled or reinforced design, and that affects weight, feel and cost. Most reputable brands offer PAS 24 tested doors and a wide colour and glazing range, with typical fitted prices of roughly £1,200–£2,500+ depending on the brand and specification. Rather than chasing a single label, the practical approach is to choose a PAS 24 rated door with a TS007 3-star cylinder in the style and price you want, fitted properly by a registered installer.
Brand matters less than specification and fitting. Knowing the common names helps you read quotes, but the security rating, cylinder and quality of installation are what protect your home.

How the brands tend to differ
Composite door brands vary mainly in how the door is built and finished. Some use a solid timber core for a heavy, traditional feel; others use a foam-filled or reinforced core with a focus on security and insulation. Finish ranges, glazing options and hardware differ too, which is partly why prices span roughly £1,200–£2,500+ fitted. The names you'll commonly see quoted include Solidor, Rockdoor, Endurance and the Composite Door Co — all widely fitted UK ranges. None is a default 'right' choice; the better question is whether the specific door meets the security standard you want at a price you're comfortable with.

How to choose a door rather than a brand
- Start with security: insist on a PAS 24 tested door — ideally Secured by Design accredited — with a TS007 3-star cylinder.
- Then style and finish: pick the colour, glazing and hardware you want; most brands cover the popular looks.
- Check the warranty: compare the door and hardware guarantees offered by the supplier and installer.
- Mind the fitting: a well-made door fitted badly is not secure — choose a registered installer who fits the brand regularly.
