Window Energy Ratings were introduced by the Government in 2005 as a means for window companies to demonstrate compliance with Building Regulations Part L concerning energy efficiency of their windows.  

The Window Energy Rating (WER) level on a scale of A++ to G, with A++ being the most energy efficient, is shown on a label attached to the window. It looks very much like the kind of label you see on domestic appliances such as fridges and washing machines.  

The more energy efficient the window is, the better it is at keeping heat in your home. This means that upgrading to more energy efficient windows can save you money on your energy bills.
