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.
