The landlord, who we will call Sue, carried out a full ‘gut and refurb’ on a house nearly 10 years ago. The works included insulating walls and floors, which resulted in an EPC rating for the property of C.
This was done under the building regulations, and Sue had a certificate. However, EPCs only last for ten years, so now she has to get a new one.
She went to the same EPC surveyor but guess what? He told her he would have to downgrade the rating to a D because he can’t actually see the insulation!
Which is a problem. Obviously, once the insulation has been installed, it will be covered up.
