British Fenestration Rating Council
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.
So, when manufacturing, installing or choosing windows or doors, remember that invisible performance matters and only a BFRC rating can be truly trusted to prove it.
