Composite Doors

Composite Doors in Northamptonshire

The most popular front door choice in the UK

Composite doors are the most popular front door choice in the UK and have been for over a decade. The combination of strength, security, low maintenance, thermal performance and design flexibility make them a practical alternative to timber and uPVC for many family homes.

We supply and fit composite front doors within an 50 mile radius of our Rushden showroom, with the full range of colours, glazing options and Ultion 3-Star security locking included as standard.

What makes this type of door different?

Composite doors are built from multiple materials bonded together, hence the name. This type of door typically has a GRP (glass-reinforced polymer) outer skin, a foam-insulated core, a reinforced timber sub-frame and a multi-point locking system.

The GRP skin gives composite front doors their resistance to weather, fading and impact damage. The foam core delivers the thermal performance. The timber sub-frame gives the structural strength for the lock mechanisms and hinges.

Compared with uPVC alternatives, composite front doors can offer greater strength and better thermal insulation. Unlike timber, composite designs are far less prone to warping or splitting and require less routine maintenance. Compared with hybrid systems, composite is generally more affordable while still offering strong security and weather performance.

Security as standard

Every composite door we supply comes with Ultion 3-Star anti-snap cylinders as standard. The Ultion cylinder is the highest-rated residential cylinder available in the UK, with TS 007 3-Star certification and Sold Secure Diamond rating.

The full security spec on our composite doors includes Ultion 3-Star cylinders, Winkhaus or Yale multi-point hook locking, reinforced hinges, anti-bump pins, and PAS 24 doorset certification available as an upgrade.

Secured by Design (the UK Police-backed certification) is available across the composite range for properties where the highest residential security spec is the priority.

Thermal performance and U-values

Our composite doors achieve U-values from 0.86 W/m²K, which is well below the 1.4 W/m²K minimum required for new front door installations under current UK Building Regulations.

The foam-insulated core does most of the thermal work. The GRP skin reduces air infiltration. The multi-point locking compresses the door against EPDM weather seals around the frame, eliminating draughts at the perimeter.

For exposed front elevations and older properties where heat loss is already higher, the thermal improvement from upgrading to a modern composite front door is usually noticeable in the first winter.

Composite door styles and panel designs

Our range includes panel designs to suit a wide variety of UK property styles. Popular options include:

  • Traditional 4-panel designs for Victorian and Edwardian terraces,
  • 6-panel styles for Georgian homes and 1930s semi-detached properties,
  • Contemporary smooth finishes for modern townhouses and new builds,
  • Cottage-style designs, including stable configurations for rural properties,
  • Half-glazed composite front doors with decorative or privacy glass,
  • Fully glazed contemporary styles with sidelights and top lights.


Each style is available in the full RAL colour palette, with dual-colour finishes giving you different shades inside and out.

Composite Door FAQs

What are composite doors?

They are external products made from several materials bonded together for strength, insulation and security. A typical construction combines a GRP outer skin, an insulated core, a reinforced sub-frame and multi-point locking. This makes composite a popular choice for front entrances across a wide range of UK homes.

How much do composite front doors cost?

Fitted composite models typically cost around £1,200 to £2,000, while supply-only options start from approximately £750. Premium specifications with upgraded security, decorative glazing, dual-colour finishes or custom colours can reach £2,500 to £3,500. The final price depends on size, glass, finish and hardware.

Are composite doors secure?

Yes, when properly specified and fitted. Our range includes Ultion 3-Star anti-snap cylinders, multi-point hook locking and reinforced hardware. PAS 24 and Secured by Design options are also available on suitable configurations for additional security.

How long do composite front doors last?

There is no fixed service life, as longevity depends on installation, use, exposure and maintenance. GRP finishes are designed to withstand everyday weather conditions with relatively little upkeep, while hinges, locks and seals should be checked and maintained over time to keep everything working correctly.

Are composite doors better than uPVC?

It depends on your priorities. Composite designs generally offer a more substantial construction, strong thermal performance and a wider choice of traditional front entrance styles. uPVC is usually more affordable and remains a practical option for back entrances or budget-led projects.

Can composite doors be repainted?

It depends on the manufacturer and original finish. Some GRP surfaces can be refinished with suitable preparation and products, but painting may affect the manufacturer's warranty or long-term appearance. Check the product guidance before changing the original colour.
