What is the WER system and why does it matter?

When researching your new windows and doors, you might keep seeing references to WER’s or Window Energy Ratings. What do they mean and why are they important for your home?

What is the Window Energy Rating system?

The WER was created by the British Fenestration Ratings Council to show how energy efficient a window or door is. With A++ being the highest and E the lowest. A similar system is used for the efficiency of household appliances such as washing machines, tumble dryers and freezers.

The Glass and Glazing Federation took over the BFRC in 2005 and continues to promote the acceptance of WERs. They are now endorsed by the government and are an integral part of compliance with Building Regulations. All newly installed windows must reach at least a C rating. The only exception to this are listed buildings, as these can have restrictions on what can be changed.

How are WER’s calculated?

The ratings are calculated on the window or door as a whole, so the material, frame design and glazing are all considered. The amount of air that leaks through as well as solar gain is measured to determine how efficient each product is. Solar gain is how much heat from the sun passes through glass.

Why should I take notice of Window Energy Ratings?

The better rating your windows and doors have, the more energy efficient your home will be. What does this mean for you?

  • Your home will be warmer and draughts and cold spots become a problem of the past
  • Your bills will be lower as you’ll need your heating less
  • Your home will be more environmentally friendly, and your carbon footprint will be reduced
  • The value of your home will increase with higher energy efficiency levels

Figures from the Energy Saving Trust suggest that a detached gas-heated home could save up to £110 a year by swapping from single-glazing to A-rated double glazing. Contact us today for more information

Helping you be as green as possible

The WER rating of your home improvements helps you make an informed and environmentally conscious choice. Before you make your final decision, ensure that you're getting the best price for the highest WER you can afford. Ask to see the WER label to make sure you get the efficiency you expected. When a home is sold in the UK it requires an Energy Performance Certificate (EPC) . These are valid for 10 years and take into account the glazing, heating and insulation of a house. The better your windows and doors are, the more desirable your home will be to buyers.
