Supreme Windows London supplies and installs aluminium windows across Croydon, Thornton Heath and the wider South London area. Aluminium is the premium choice for windows: exceptionally strong, slim and modern. Because the frames carry the weight, they can be far thinner than uPVC, giving you more glass, more light and cleaner sightlines. Every installation is FENSA registered.

Why choose aluminium windows
Aluminium windows are built to last and suit contemporary and period homes alike across South London.
- Slim frames and larger glass area for more natural light
- Extremely strong and durable, with a lifespan of 30 years or more
- Low maintenance, never needing painting and only an occasional clean
- Thermally broken frames for excellent energy efficiency
- Secure by design, with multi-point locking as standard
- A huge choice of RAL colours, including dual-colour options
Aluminium or uPVC: which is right for you
Both are excellent, and the right choice depends on your priorities. uPVC offers the best value and suits most homes. Aluminium costs more but gives you slimmer frames, a more modern look, larger panes of glass and greater strength, which makes it ideal for big picture windows and contemporary properties. We are happy to talk through both honestly at your survey and recommend what suits your home and budget.
Colours and finishes
Aluminium takes colour beautifully, so your windows can match or contrast with your property exactly:
- Anthracite grey, the most popular modern finish
- Black, white and the full RAL colour range
- Dual colour, with a different shade inside and out

Frequently asked questions
How much do aluminium windows cost in London?
Aluminium sits above uPVC on price because of the material and the slimmer engineered frames. Because every job is different, we give a fixed written price after a free survey rather than a misleading average. Request a quote for an exact figure with no obligation.
Are aluminium windows more energy efficient than uPVC?
Modern aluminium windows use a thermal break, an insulating barrier within the frame, which gives excellent energy efficiency. Paired with double or triple glazing, they keep your home warm and your bills down.
How long do aluminium windows last?
Aluminium is one of the longest-lasting window materials, commonly lasting 30 years or more with very little maintenance.
What colours are available?
The full RAL range, including anthracite grey, black and white, plus dual-colour options with a different finish inside and out.
Are your windows FENSA registered?
Yes. Every installation is FENSA registered and certified as compliant with building regulations, with a certificate provided on completion.
