I have this issue too. 1600 in credit haven't been billed in forever. They sent me a letter advising the billing issue was resolved. And that as a member of the ethical billing board they can only bill me for 12 months. Over the last 4 years my annual usage has been 800 quid. They tell me the bill will be 800... Guess how much the bill was for?
1550. Woop 50 rebate.
Sufficed to say a manual backbilling is in progress, however apparently applying my well established annual usage to my account, just billing that and starting over with new readings is TOO difficult. So I am advised to wait a further 3 months to be billed manually.
In the meanwhile I've had my DD moved from 60, to 5, to 110, to 225, to 40. I had five DD change letters in one week from them.
Farcical. This backbill is the last straw then its offgem and small claims.
