Report
We have recently had our old conservatory renovated with a solid slate effect roof. We are very pleased with it as its much cooler when its hot and warmer when cold. Unique were very professional, the installers work very hard and am very happy with the end result.

Report
We recently had our front windows changed by Unique and would highly recommend. From start to finish they were highly professional and provided a great service, the rep was great, no sales nonsense, he explained the product well and the price was great in comparison to other quotes that we received. Very impressed that they were fitted 3 weeks later, great tidy job!

Report
I don't often write reviews, but we were so pleased with the French doors installed by this company that I felt I had to. Price - after many quotes, Unique was one of the least expensive - some others, twice the cost
Value for money - very good quality
Installation - installed quickly and on date promised. The fitters were tidy, courteous and efficient. Highly recommenced and would use again for other doors and windows if needed.
