Re: No accurate bills
If your gas is so high have you checked that the meter reading and billing units are the same? When I moved house into the one with the smart meter I gave the reading as xxxx kwh (as that was on the IHD) and they billed it as cubic metres (or vice versa) which gave me a gas bill way higher than it should have been. It was only when they went to treble my DD payment I realised what had happened.
