Thank you all so much for your answers. Dad is 86 so it's hard for him to understand. I don't think his tarrif has changed, but I don't know what his tarrif has been. It looks as though they are entitled to charge it then from your excellent answers, although dunnitall I agree, they do have you by the s & c's ! Ofgem definitely said it was a blatant lie, I have the email, but I must admit the rest of it was gobbliedook and hard to understand ! I may look into switching supplier for him as Ofgem also said that not all suppliers are charging it. I will study all your answers and the links and try to give my Dad an answer he will understand. Thank you again.
