A Building Energy Rating (BER) certificate rates your home’s energy performance on a scale between A and G. A-rated homes are the most energy efficient while G-rated are the least energy efficient.
It is a legal requirement that all properties offered for sale has a current BER certificate. If you bought the house recently this document may be with the deeds but if not, you would need to commission one. BER certificates last 10 years. Buyers are now making more conscious choices seeking environmentally friendly and cost-effective heating.
