Iam in the middle of changing suppliers. But having problems i have a prepayment meter and i have storage heaters but i only use one and i turn my hot water of during the day. The problem is the company iam trying to go with is saying i have 2 meters, so i gave them 2 supply numbers for them. I think i have economy 7 because my hot water comes on when iam in bed. but they still say iam may be on a different tarrif and i get cheap electric through the day and at weekends which i find this hard to believe. They said its called total heating with total control. So basically at the moment i cant change my supplier for some reason unless i change my meter to economy 7. My neighbour has the same house and probably uses more heaters than me with a prepayment meter and he changed to e.on with no problem. does anyone have advise on this
