Energy Rating

We only fit high performance energy efficient A-C rated windows.

What are Window Energy Ratings? (WER)

Windows are now rated on how efficient they are at saving energy lost through your windows. The same as other household products like white goods (washing machines and fridges for example) windows use the A to G scale to show how efficient the product is. More energy efficient windows will result in lower heating bills.

What do WER labels tell you?

The window energy-rating label will show you which rating that product has achieved. The range graded from A to G. We only fit windows rated A or C. Both are energy efficient with A rated windows being the most efficient. Choose which rated window you want according to your needs and budget.

How are the ratings calculated?

There are a number of factors that determine what rating is given to a window. When the window is tested the efficiency of the UPVC frame, the glass heat loss, solar gain (energy from the sun) and how draught proof the seals are, together equal a score. This score is converted into an easier to understand rating. The British Fenestration Council (BRFC) window energy-rating scheme checks all components to ensure the final window achieves the energy efficient standard claimed. The results are then translated into the A-G grading system for easier understanding.
