im with you old_geezer, bigest waste of time and money,when finally finding the property of your dreams are you going to back out as it has a poor energy rating ? i doubt it.
The most stupidest one is when i sat in a hospital waiting room and saw the EPC on the wall , apparently it costs a fortune to be assessed and a £5,000 fine if its not displayed, lets be honest the last thing on your mind when in hospital is going to be the energy rating,perhaps you are supposed to find the most energy efficient hospital before you become ill or have an accident.
