Please can someone advise? We were fitted with economy 7 heaters back in 2007 & Scottish Power came & fitted the meter accordingly. Since then my bills have been astronomical. We asked an electrician friend & he said the tails (wires) hadn't been fitted to an economy 7 meter so we have been paying for 3 years at flat rate. Should we have 2 meters for economy 7 View media item 22255
