The short answer
Common UK composite door brands include Solidor, Rockdoor, Comp Door, Hurst, Endurance and Door-Stop, each with a different core construction, skin type and style range. Solidor is known for a solid timber core and a wide colour and style range. Rockdoor uses a distinctive multi-layered construction with an ABS skin noted for impact and security. Comp Door and Hurst manufacture solid-core GRP doors with strong security specifications. Endurance offers a thick solid-timber-core door, and Door-Stop is a widely available GRP option. Brands are usually supplied and fitted by local installers rather than sold direct, so the installer often determines which brands you can choose from.
The UK market has several established composite-door makers, each with its own construction approach and style range.

The main UK brands
Several manufacturers dominate the UK composite-door market, and most homeowners encounter them through a local installer who supplies and fits one or more ranges. The brands differ mainly in core construction, skin material, security specification and the breadth of colours and styles they offer. None is universally best; the right one depends on your priorities and what your installer carries.
The table gives a quick overview of well-known names and their defining characteristics, drawn from each manufacturer's published specifications. Because specifications change, always confirm the current build and security rating of the specific door you are quoted.
| Brand | Construction | Known for |
|---|---|---|
| Solidor | Solid timber core, GRP skin | Wide colour and style range |
| Rockdoor | Multi-layered, ABS skin | Impact resistance, security |
| Comp Door | Solid-core, GRP skin | Security specification |
| Hurst | Solid-core, GRP skin | Broad range of designs |
| Endurance | Thick solid-timber core | Substantial, solid feel |
| Door-Stop | GRP composite | Widely available, value |
Indicative summary; confirm current specifications with the installer.
How the brands differ
The clearest difference between brands is core and skin. Solidor and Endurance emphasise a solid timber core for a heavy, rigid feel, with Endurance using a particularly thick door slab. Rockdoor takes a different approach, with a multi-layered construction and an ABS skin noted for impact resistance and a distinctive security build that includes internal reinforcement.
Comp Door and Hurst manufacture solid-core doors with GRP skins and focus on strong security specifications and a wide choice of designs. Door-Stop is a widely supplied GRP composite door, often offered as a value option through many installers. Each brand also differs in colour palette, glazing designs and hardware options, so the look and feel vary as well as the construction.
Security and certification across brands
Most reputable composite-door brands offer doors that meet recognised UK security standards, but it is the specific door set and its locking that carries the certification, not the brand name in the abstract. Look for Secured by Design accreditation and PAS 24 testing on the particular door and lock combination you are buying.
Cylinder and multipoint lock quality vary by specification level even within a brand, so a budget version of a good brand may have a basic cylinder that is worth upgrading to an anti-snap 3-star unit. When comparing brands, compare like-for-like security specifications rather than assuming a well-known name guarantees the highest rating on every door.
Choosing between brands
Because brands are usually fitted by installers, your practical choice often starts with finding a good installer and seeing which ranges they offer. From there, compare the things that matter: core construction, skin type, security certification, glazing options, colour range and the guarantee on both the door and the installation.
It is worth viewing finished sample doors in person, as photographs flatten the differences in grain, colour and substance. Ask each installer to quote the same security specification so you can compare prices fairly. Ultimately, a quality door from any of the established brands, correctly specified and well fitted, will serve a UK home well; the differences between them are real but smaller than the difference between a quality door and a cheap one.
Frequently asked questions
Are some composite door brands more secure than others?
Security depends on the specific door set and its locking, not the brand name alone. Most reputable brands offer Secured by Design certified options, but specification levels vary, so compare like-for-like security ratings and insist on an anti-snap cylinder whichever brand you choose.
Can I buy composite door brands directly?
Most UK composite-door brands are supplied and fitted through local installers rather than sold direct to homeowners. This means the brands available to you often depend on which ranges your chosen installer carries.
What is the difference between Solidor and Rockdoor?
Solidor uses a solid timber core with a GRP skin and offers a wide colour and style range. Rockdoor uses a multi-layered construction with an ABS skin, noted for impact resistance and a distinctive security build. The two suit different priorities around feel, finish and construction.
