BER Assessor

SEAI Registered

A Building Energy Rating (BER) evaluates your home based on how energy efficient it is. The scale goes from A to G, with A-rated homes being the most energy efficient and G-rated homes the least.

The better your BER, the more energy efficient your home is. Homes with a good BER rating will:

​

  • Stay warm for longer

  • Have lower energy bills

  • Have lower carbon emissions, making them more environmentally friendly
