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.
Proof your products will perform as promised.
BFRC collaborates across the window and door industry with organisations big and small, private and government in the United Kingdom and abroad, to raise standards of performance. If you have an interest in energy efficiency in buildings then let's discuss common goals and possible collaboration.
An economics graduate, Lis started with BFRC nine years ago on the technical and administration side before becoming Operations Manager in 2012 and then Operations Director in 2017.
She has been instrumental in making BFRC a key company in the industry, focusing on areas such as market and product development. Under her tenure, the BFRC has developed the range of products rated under the system as well as the homeowner’s certificate and the brand marketing of the BFRC.
