A year ago my Housing Association installed a new 'Wet Electric Central Heating System' with a Economy10 Tariff from Hydro Electric.

All the tenants in the area were told that Hydro were the only supplier using Economy10, so we went with that.

Since then we have received huge bills ranging frpm £110 a month for a one-bed flat, to £2400 per year for a 4 apartment.

After numerous calls to Hydro, I have found out that the meter fitted (by Scottish Power on a sub-contract basis) was in fact an Economy7. I have been told that the fault is to do with the switch over from BST to GMT, but I'm dubious because I feel that still wouldn't account for the huge discrepancies.

Hydro have offered to change the meters over, but I get the feeling I/We will have a battle on our hands trying to get the proper amount of recompense for overpaymenticon. its as if they are trying to blind us with science!!

Does anybody know of any Laws or Statutes, for example, Trading Standards etc., that I can use to get them to give me a proper and true explanation of what went wrong, and any guidance relating to Consumer Rights.

also has anybody else had this problem?

Any help would be much appreciated.
