Ok but Scottish Hydro Electric is not mentioned so am I to assume they DO NOT subscribe to this charter? Or do you know if they have specifically excluded themselves from this charter? The reason for the question is that I have been back billed > 2 years by Scottish Hydro Electric as a result of their error in not billing me. I have been a customer of Scottish Hydro Electric at my address for the past 7 years when they suddenly stopped billing.

Does Scottish Hydro Electric subscribe to this code of practice?

"Under the Code, from 1 July 2007, where the suppliers are at fault in not billing a domestic customer, they will not send a bill which includes unbilled energy consumed more than 1 year previous to the bill being issued." Can I clarify this applies in the situation where my energy supplier stopping billing for usage in error and only noticed after > 2 years? i.e. it was their fault for not billing but I didn't inform them of this and it was an audit by the energy company which identified the problem.
