Energy Efficient Windows


If you’re looking to improve the energy efficiency of your home but are struggling to understand what all the ratings mean then you are not alone in this.

Replacement windows are a significant investment in time and money, so getting it right is important. Get it wrong and you can spoil the look of your home and possibly end up with draughty windows that let in the cold. With the right windows, your home can become a place of comfort and warmth that you can be proud of.

Understanding energy ratings

Modern, high-quality timber windows will last for many years, so you’re unlikely to upgrade them very often. So, when you do decide to replace them, it’s worth installing new windows with the best energy ratings.

The British Fenestration Ratings Council (BFRC) window energy rating scheme is the UK’s national system for rating the energy efficiency of windows.  Window Energy Ratings (WER) are a guide to the energy performance of your windows. This means that you just need to look for the A++ to E ratings similar to white goods in your home, and remember that the higher the energy rating, the more energy efficient it is.

Benefits of energy efficient windows

  • Reduced energy bills
  • Smaller carbon footprint
  • A more comfortable home – energy efficient windows reduce heat loss which means fewer draughts and cold spots
  • Peace and quiet - as well as keeping the heat in, energy efficient windows insulate your home against external noise. 

Installing BFRC rated energy efficient windows will ultimately save you money on your energy bills. Many experts predict the costs of heating homes will continue to rise over the coming years. So, being able to reduce our energy bills and reduce the carbon emissions from our homes by making them more energy efficient is becoming increasingly important.
