WER RATED 

Windows are now rated like any other white good or even your entire home using the simple BFRC (British Fenestration Rating Council) system, These tests provide a rating of A-G with an A rating being the best. Window Energy Rated windows of C (the minimum standard) ensure you save money on heating bills and protect the environment from unnecessary wastage. 

Reducing heat loss doesn’t mean you can’t maintain style, which is why all of our “A”-“C” Rated windows are available in any style and any colour in our range.
