Why Part L matters for your front door
Part L of the Building Regulations sets the minimum U-value for new and replacement doors in England and Wales at 1.4 W/m²K. Our aluminium front doors hit 1.2 W/m²K as standard — with the same warm, draught-free feel the Scandinavian passive-house market swears by.
The rest of the high street? Flimsy composite doors with thin foam cores that sag in summer, distort in winter, and fail Part L without upgraded glass. Our aluminium panel doors use a 34 mm polyamide thermal break, 48 mm insulated panels, triple-gasket weather seals, and a concealed 3D-adjustable hinge system that keeps the reveal perfect — for life.

Choosing an aluminium front door in 2026
Your front door is the most-touched item on your house. It’s the face of the building, the first line of defence against weather and burglars, and one of the biggest visual upgrades you can make.
Composite vs aluminium — why aluminium wins
Most high-street front doors are composite — foam-filled cores with a GRP skin. They look fine on day one but the skin warps, fades and distorts in full sun. Our aluminium front doors have a solid aluminium skin, high-density insulated core, and a thermal break. Stays square for decades.
How much does an aluminium front door cost?
A composite door runs £900–£1,600 fitted. A premium aluminium door like ours runs £1,800–£3,500 fitted depending on size, glass, panel design and extras. The life is double, security tested higher — think 20-year cost.
Security — what to look for
PAS 24 is the British break-in test. Every GWS aluminium front door is PAS 24 certified. Look for 3-star anti-snap cylinder, 6-point hook locking, internal glazing beads, anti-lift rollers — all standard on ours.
Should I get ekey fingerprint entry?
ekey is an Austrian biometric system built into the frame. Up to 99 fingerprints, works in rain, snow, with wet or dirty hands. If you’re sick of losing keys — ekey solves it.
Panel design choices
120+ designs: flush panels for contemporary, grooved for subtle texture, traditional with mouldings for period homes, Art Deco with horizontal ribs. Glass side lights and top lights in any configuration. Dual-colour at no surcharge.
Thermal performance and Part L
Part L requires 1.4 W/m²K or better. Our aluminium front doors come in at 1.2 W/m²K standard, 0.8 W/m²K with triple-glazed side light. Saves money on heating, keeps the hallway warmer. Building control signs off without question.
How long does it take?
Standard lead time from order is 4–6 weeks for manufacture. Install day is usually a single day. Priority fast-track production available for tight deadlines.
Aftercare
Maintenance-free. Wipe down with warm soapy water twice a year. Lubricate the lock strip once a year. No painting, no sanding, no re-staining. That is the beauty of aluminium.

What Our Customers Say
“Replaced our old composite door with the aluminium one from GWS. The difference is ridiculous — it’s solid, silent, and ekey means the kids can’t lose the keys. Worth every penny.”
“We had been quoted for a cheap composite that didn’t hit Part L. GWS came in at a similar price with a door that actually passes building control and looks like something off Grand Designs.”
“Used GWS on three plots now — the panel doors arrive on time, sized to the mil, and the fingerprint entry is a massive selling feature to my buyers.”
