Hi Harry… so the person whose name was on the Account with EDF… they will be getting these back-dated bills… not you.
well its my partners mum’s house and as yet she hasnt had a bill.
Then presumably her EDF contract did not fall into that category… I’m sure she won’t be complaining that she has escaped… 
and if EDF have made a mistake in NOT billing her … let’s hope they don’t realize until the time-limit is up…
not sure, i know she is expecting to be billed and is not happy but its not nice they are doing it but its something that they are technically due.
Frankly Harry… I reckon none of us is particularly happy when we receive a bill… any bill for that matter… but we just have to grin and bear it. 
… and pay it…!!!
unless they manage to reverse it and then everyone has to battle with edf o get their money back…
Just wondering if any of the alternative energy sellers have added this on as well, I guess they buy their electricity from EDF too.
