uPVC Doors
uPVC doors are a practical, cost-effective choice for front and back entrances, offering excellent weather resistance, low maintenance and reliable insulation for secure everyday access. They can be tailored with decorative glazing, colour options and hardware finishes to suit your home.
Timber Composite Doors
Composite doors are ideal for homeowners who want enhanced security, premium design and excellent thermal performance. They blend classic style with modern strength and durability, available in a wide choice of colours, woodgrain finishes, glazing designs and hardware options.

Whether for a cosy cottage, suburban home or countryside escape, a stable door offers a unique blend of classic looks and practical function. They’re a charming option for rear entrances, combining ventilation, flexibility and traditional style.

Composite vs uPVC Front and Back Doors
Both materials make excellent front and back doors — the right choice depends on your budget, style and performance priorities.
Composite doors combine a high-density insulating core with tough outer layers such as GRP, giving outstanding insulation, security and durability with a premium finish. They resist warping, cracking and fading, come with multi-point locking, and need only an occasional wipe down.
uPVC doors offer affordable elegance with a winning combination of versatility, energy efficiency and low maintenance. They won’t rot, warp or corrode, insulate well, and are a smart choice for cost-conscious homeowners who still want security and style.
Still deciding? Read our guide to choosing between uPVC and composite doors. For independent advice on energy efficiency, see the Energy Saving Trust guide to windows and doors.
