Aluminium offers excellent value compared to steel, and our pricing reflects that. For London projects, internal aluminium doors (single leaf) typically start from £1,800 to £3,500, external aluminium doors from £2,500 to £5,500, aluminium-framed windows from £600 to £1,200 per square metre, and internal screens or partitions from £1,000 to £2,200 per square metre. The final cost depends on dimensions, glazing specification, finish, hardware, and any fire-rating requirements. We provide a clear, itemised quote after your initial consultation.

Aluminium systems generally have shorter lead times than steel. Most projects are completed within 4 to 6 weeks from design approval to installation, depending on complexity and order volume. Larger or more technically demanding commissions may take slightly longer, and we will confirm the timeline upfront. You will receive regular updates throughout the process.

Yes. We offer a complimentary survey across all London boroughs. Our team will visit your property, take precise measurements, assess the existing openings, and discuss the best aluminium system for your space. This is particularly useful for older London properties where window reveals and structural conditions can vary significantly from room to room.

This depends on your priorities, but for most London clients aluminium offers the strongest overall package. Modern aluminium systems deliver excellent thermal efficiency, often outperforming steel thanks to advanced thermal break technology that comfortably exceeds Part L building regulations. Aluminium is also lighter, more corrosion-resistant, and requires virtually zero maintenance over a lifespan of 30 to 40 years.

Where steel retains an edge is in ultra-slim sightlines (around 20 mm versus 40 to 60 mm for aluminium) and a marginally longer lifespan of 50 years or more. Steel also carries a premium price tag, typically 20 to 40 per cent above an equivalent aluminium specification. If your priority is energy efficiency, low maintenance, and strong value for money, aluminium is the smarter investment for the vast majority of London residential and commercial projects.

Fire-rated aluminium doors are available for projects that require certified fire protection. An E30 rating confirms the door will contain flames and smoke for 30 minutes, which is the most common requirement in residential settings. EI ratings add heat insulation: EI30, EI60, and EI90 doors resist fire, smoke, and radiant heat for 30, 60, or 90 minutes respectively, while also limiting temperature rise on the protected side.

Across London, Approved Document B and the London Plan frequently require EI30 or above for HMOs, shared corridors, and multi-occupancy residential buildings. We can supply fire-rated aluminium systems to the appropriate standard and advise on the correct specification based on your building’s fire strategy.

Absolutely. While genuine Crittall products are steel-only and manufactured exclusively by Crittall Windows Ltd in Essex (with lead times of 12 to 16 weeks and a premium price point), modern aluminium systems can replicate the same slim-framed, grid-pane aesthetic at a fraction of the cost. Our Crittall-look aluminium doors and windows deliver the iconic industrial style with the added benefits of superior thermal performance, lighter weight, and minimal maintenance. Lead times are typically 4 to 6 weeks, and pricing is generally 30 to 50 per cent below genuine steel Crittall. For most London homeowners, this represents the best balance of style and practicality.

This requires careful consideration. In London’s many conservation areas, from Hampstead to Clapham, aluminium windows are increasingly accepted by planning authorities, particularly when the design closely matches the proportions and sightlines of the original fenestration. However, for Grade I and Grade II listed buildings, conservation officers tend to favour steel or timber, as these materials are more historically authentic.

If your property is listed, you will need Listed Building Consent from your borough council, and Article 4 Directions may restrict permitted development rights in conservation areas. We can prepare the drawings and specifications to support your application and advise on whether aluminium will be acceptable for your specific property. Planning consent in London typically takes 8 to 13 weeks.

We serve all 32 London boroughs, from Enfield and Barnet in the north to Croydon and Bromley in the south, and from Hillingdon in the west to Barking and Dagenham in the east. Whether your project is a single window replacement in Greenwich or a full commercial fit-out in the City, we have the capacity and experience to deliver. For projects outside Greater London, get in touch and we will confirm feasibility.
