One in every 12 properties sold achieved an energy efficiency rating of A or B on its EPC, 47% of properties selling with a D rating. Just 6% of re-sale properties sold achieved the A or B rating, However over 60% of re-sale properties have the potential, with improvements, to hit that grade. As autumn approaches and the conversation in many households turns to extra layers versus heating on, boosting your homes EPC rating may well keep you warm and help boost your sale price.
