Doors explained
Aluminium front doors have become the premium choice for UK homeowners wanting contemporary style with serious security. They offer slimmer sightlines than uPVC or composite, lifespans of 40+ years and zero swelling, warping or rotting. Expect to pay £1,800–£4,500 fitted including VAT — more than uPVC but less than top-end timber.
What Does the Work Involve?
A modern aluminium front door is a multi-chamber thermally broken extrusion — a polyamide strip separates the inside and outside of the frame to break the cold bridge. The slab is typically a foam-filled aluminium skin with optional glazed panels. Installation involves removing the existing door and frame, fitting a new cill, plumbing the frame into the opening, mechanically fixing through the jambs, foam-insulating the perimeter, and trimming inside and out. Multi-point locking is standard. Quality units come pre-finished in any RAL colour with a polyester powder coat that holds for 20–25 years.
Typical Costs
| Item | Low (£) | High (£) | Notes |
|---|---|---|---|
| Entry-level aluminium door, supply | 1,400 | 2,000 | Single colour, no glazing |
| Mid-range with side panel | 2,200 | 3,200 | Glazed sidelight, RAL colour |
| Premium designer door | 3,200 | 5,500 | Stainless inlays, smart lock |
| Installation labour | 400 | 700 | Two fitters, half-day |
| Old door & frame removal | 80 | 180 | Make-good of brickwork extra |
| Smart lock upgrade | 250 | 650 | Yale, Ultion Nuki, Mul-T-Lock |
How Long Does It Take?
A single front door swap is a one-day job for two fitters. Bespoke RAL colours have a 6–10 week lead time from order to delivery. Pivot doors or oversized units may need a structural opening — add 1–2 days for builder work.
DIY or Professional?
This is a professional install. Aluminium doors are heavy (35–60 kg), and the manufacturer's warranty is typically void if not fitted by an approved installer. Squareness tolerances are tight; a 3 mm twist will bind the multi-point lock. Use a FENSA or Certass registered company so you get the building-regs self-cert paperwork.
Choosing the Right Tradesperson
Confirm the installer is FENSA or Certass registered. Ask which brand they fit — Origin, Schueco, Smart Systems and Reynaers are the UK market leaders. Ask for the U-value of the complete door (not just the slab) — aim for 1.2 W/m²K or lower. Check the locking platform — look for PAS 24 and Secured by Design accreditation. Always get the warranty in writing — 10 years on the frame and 5 years on the locks is standard.
UK Regulations
External doors must meet Approved Document Part L for thermal performance — maximum U-value of 1.4 W/m²K for replacements. Approved Document Part Q applies to new dwellings and requires PAS 24:2022 security testing. Installation by a FENSA, Certass or BSI registered installer self-certifies compliance and saves a £100+ building-control notice. Listed buildings need consent before any door change.
Common Problems
- Thermal bridging: Cheap aluminium doors without a polyamide thermal break can ice up on the inside in winter.
- Hinge sag: Heavy doors stress the hinges — insist on three or four roller-cam hinges, not two flag hinges.
- Colour fade: Cheap powder coats fade on south-facing doors after 5–7 years. Marine-grade qualicoat is worth the upgrade.
- Lock alignment drift: Settling causes the multi-point keeps to drag; quality installers leave 3 mm shim packs accessible for re-adjustment.
Frequently Asked Questions
Are aluminium doors more secure than composite?
Aluminium frames are stiffer than composite or uPVC frames, so the multi-point lock keeps stay properly engaged under attack. Combined with a 3-star Sold Secure cylinder and PAS 24 testing, they are among the most secure residential doors on the UK market.
Will an aluminium door be cold inside?
Not if it has a polyamide thermal break and foam-filled slab. Modern units achieve U-values of 0.9–1.2 W/m²K, which is comparable to or better than composite doors.
Can I get any colour?
Yes — most manufacturers offer the full RAL palette and increasingly Farrow & Ball matches. Dual colour (different inside/outside) is standard at no extra cost on most ranges.
Do aluminium doors rust?
Aluminium does not rust because it forms a stable oxide layer. Powder coat protects the surface from oxidation and weathering for the life of the door.
How long do they last?
40+ years for the door slab and frame. The locks may need replacement after 15–20 years of daily use, and the powder coat may need refreshing on south-facing elevations after 20–25 years.
Are they good value compared to composite?
Composite doors are typically £1,200–£2,500 fitted. Aluminium is £600–£2,000 more on average, but offers better lifespan, slimmer frames and a wider colour range. For a forever-home, aluminium pays back; for a 5–10 year stay, composite is usually adequate.
