SW20 energy-efficient window installations

Here at Unique Windows, we understand the importance of energy-efficient windows in Brixton. As well as saving our customers money, our windows will reduce your carbon footprint and benefit the environment.

Our double glazing is A-rated, which means each window will have superior thermal performance as standard and can reach the highest energy efficiency rating available. Our windows are multi-chambered, so will trap warm air inside.

We are also proud to offer triple glazing as an option for all our windows. Triple glazing will maximise your property’s energy efficiency and make it even more warm and secure. With triple glazing, instead of two panes of glass, there are three panes of glass so as well as energy efficiency, they will enhance security and noise insulation.

Very impressed with the service provided, from the initial consultation to the final installation, everything was dealt in a very professional way.


Amazing job, I really recommend Unique Windows (London). They fitted the new doors and removed the old ones, left the place looking as it was and this was all done within a week of getting the quote, amazingly fast and reliable service with quality trades people.


We had changed all the windows in the house. They look very smart and elegant. So much that I only had praises from my neighbours and friends. Unique windows did a fantastic job at a very competitive price. Very tidy, quick and efficient. Overall, an excellent customer service. I have already recommended Unique Windows to my neighbours and friends, and I believe they have contact this company already. I will certainly use them again.


Very pleased with our new doors and windows. The fitting is excellent and Unique Windows were able to accommodate a couple of non-standard requests. Price was fair and communication clear. I would use them again in future for the remainder of the windows on our house and recommend.
