To help you identify the energy efficiency standards of a window, all replacement windows sold in the UK have a Window Energy Rating (WER) using a traffic light type of system. It’s very similar to the way white goods are energy labelled, such as fridges, freezers and washing machines, with them rated from A+ – G.
In the BFRC Rating Scheme, A+ rated windows are the most energy efficient windows you can buy in this country. Not only is this system designed to highlight the energy efficiency standards of replacement windows, but it also shows whether they comply with Building Regulations.
Windows with an A or A+ rating are certain to make your home feel wonderfully warm and fuel efficient.
It is a legal requirement that any new or replacement windows have a minimum WER of C. For more info about anything to do with energy ratings, speak to an advisor.
