Window Energy Ratings

The Window Energy Rating (WER) labelling scheme was launched in the UK by the
British Fenestration Rating Council (BFRC), a Government-supported independent
body. By using information contained on the label, consumers can reliably compare
one product with another and make informed decisions regarding the energy performance of a window. The A (best) to G (worst) rating system is similar to the
labelling already used on white goods.
