Aluminium doors cost roughly 50% more than uPVC but last twice as long, making them cheaper per year over a 30-year homeownership period.
The upfront cost of an aluminium door is higher than uPVC, but the long-term value is better. A standard aluminium door costs around 50% more to install than a comparable uPVC door, according to Glass and Glazing Federation member price data (GGF, 2026). However, aluminium doors have an expected lifespan of 30 years or more, while uPVC doors typically last 15 to 20 years (FENSA average lifespan report, 2026). Over a 30-year period, the cost per year of an aluminium door is lower because you will not need to replace it halfway through your ownership.
Aluminium doors cost £1,800–£3,200 installed in 2026, roughly 50% more than uPVC. They last 30+ years, making them cheaper per year over a 30-year period. Check long-term savings vs uPVC and composite.

The average installed price for a standard aluminium door in 2026
A single aluminium front door, including frame, hinges, letterbox, and standard double glazing, costs between £1,800 and £3,200 fully installed. This figure comes from the GGF member price survey for 2026 (GGF, 2026). A matching aluminium back door averages £1,500 to £2,800. French or sliding aluminium patio doors with two panels range from £2,500 to £4,500 (Checkatrade UK average cost data, 2026). These prices include fitting by a qualified installer but exclude any structural alterations to the door opening.
Quick numbers Aluminium vs uPVC vs composite doors
| Door type | Average installed cost (GBP) | Expected lifespan (years) | Typical energy rating (A–G) | Average U-value (W/m²K) | Maintenance cost per year (GBP) |
|---|---|---|---|---|---|
| Aluminium (standard) | £1,800–£3,200 | 30+ | A | 1.2 | £0–£5 |
| uPVC (standard) | £1,200–£2,000 | 15–20 | C | 1.4–1.6 | £0–£5 |
| Composite (standard) | £1,500–£2,800 | 25–30 | B | 1.2–1.8 | £5–£10 |

Aluminium doors achieve a U-value of 1.2 W/m²K or lower — better than the Building Regulations minimum
U-value measures how much heat passes through a material. A lower U-value means better insulation. Most new aluminium doors are filled with thermal foam and use a polyamide thermal break, which stops cold bridging between the inside and outside faces. A standard uPVC door typically achieves a U-value of 1.4 to 1.6 W/m²K. Composite doors vary widely, ranging from 1.2 to 1.8 W/m²K (DESNZ Standard Assessment Procedure tables, 2026). The Building Regulations minimum for replacement doors in England and Wales is a U-value of 1.6 W/m²K or lower. A thermally broken aluminium door with a U-value of 1.2 W/m²K will save roughly £30 to £50 per year on heating bills compared to a C-rated uPVC door (British Fenestration Rating Council data, 2026).
Aluminium doors are the most energy-efficient option for UK homes in 2026
For standard door types available to UK homeowners, aluminium doors offer the best thermal performance when correctly designed with a thermal break. A-rated aluminium doors are widely available, and A+ and A++ ratings are becoming common for premium models (BFRC energy-rating database, 2026). They also provide superior airtightness compared to uPVC or timber doors, which reduces drafts and improves overall home comfort (DESNZ product characteristics database, 2026). If maximum energy efficiency is your priority, a thermally broken aluminium door is the strongest choice among standard door options.
You must use a FENSA-registered or CERTASS-certified installer for Building Regulations compliance
Under Building Regulations Part L in England and Wales, and Section 6 in Scotland, any replacement door must meet minimum energy efficiency standards. A FENSA-registered or CERTASS-certified installer can self-certify that the work complies with these regulations. If you use an installer who is not registered with one of these schemes, you must submit a separate Building Control application and pay the associated fee (GOV.UK Building Regulations guidance, 2026). Check the FENSA or CERTASS register online before hiring. The installer should also be TrustMark-registered for consumer protection (FENSA website, 2026). How to check if your installer is FENSA registered
Aluminium doors require virtually no maintenance beyond occasional cleaning
The powder-coated finish on aluminium doors is factory-applied and resistant to fading, chipping, and corrosion for 20 years or more. Unlike timber doors, aluminium does not need repainting or varnishing. Unlike uPVC, it does not yellow or become brittle over time. Annual maintenance is simple: wipe down the frame and panels with soapy water, and lubricate hinges and locks once a year (GGF maintenance guidelines, 2026). This low maintenance requirement contributes to the lower long-term cost per year compared to other materials.
The average lead time for a bespoke aluminium door is 6–10 weeks in 2026
Most aluminium doors are made to measure rather than stocked as standard sizes. The average lead time for a bespoke aluminium door is 6 to 10 weeks, according to the GGF industry lead-time survey for Q1 2026 (GGF, 2026). Standard sizes may be available in 4 to 6 weeks. Supply chain delays that affected the industry between 2022 and 2024 have largely resolved, and current lead times are back to pre-2020 norms. Expect an additional 2 to 3 weeks if you order a RAL colour that is not in the manufacturer’s standard range. How to choose the right RAL colour for your aluminium door
