The British Fenestration Rating Council is the UK’s most trusted rating council for verifying the energy performance of windows and doors. In 1997, BFRC was founded to establish the window energy rating system for the UK, to raise standards and drive performance in the industry. Now the BFRC is Europe’s No. 1 ratings council, with the most widely-used rating system.


The BFRC rainbow rating confirms products have been independently verified by experts in building physics and have been assessed to ensure the whole system will perform as promised. This gives installers and homeowners the evidence they need to make the right choice for each home’s window and door energy performance requirements.

Windows and doors can play a vital role in reducing the level of noise entering a home, particularly for dwellings close to roads, railways or impacted by air traffic noise. With homes increasingly becoming peaceful retreats from a hectic outside world, making them quieter, more pleasant places to be can also improve wellbeing.

BFRC Noise Reduction Ratings let window & door system houses and manufacturers prove the acoustic performance of window and door products with the highly recognised BFRC ‘rainbow’ rating label. These easy to understand ratings empower installers and homeowners to compare products based on their noise reduction performance rather than simply on price.
