british federation rating council

BFRC- British Fenestration Ratings Council

The BFRC Scheme is the UK’s national system for rating the energy efficiency of windows and is recognised within the Building Regulations as a method to show compliance for your replacement windows installation. Window energy Ratings use a consumer-friendly traffic-light style A-E ratings guide similar to that used on ‘white’ goods (such as fridges, freezers, washing machines etc). This ratings label can be used by you to make more informed choices about the energy efficiency of the windows you are looking to purchase.
