Dear Sir or Madam,
Complaint: back bill for energy used more than 12 months ago
Your bill dated [DATE OF BACK BILL] charges me for [ELECTRICITY / GAS] used from [START DATE OF PERIOD BILLED] to [END DATE OF PERIOD BILLED].
Under standard licence condition 21BA of your supply licence, you may only bill me for energy reasonably considered to have been used, and standing charges accrued, in the 12 months before the date of the bill. Part of this bill, from [START DATE OF PERIOD BILLED] to [DATE 12 MONTHS BEFORE THE BILL], is for energy used more than 12 months ago.
For that earlier period (tick what applies):
[ ] I have not had an accurate bill before.
[ ] I was not told what I owed in a statement of account.
[ ] My Direct Debit was set too low by you to cover my use.
I have not obstructed you from billing me. [EXAMPLES: I GAVE METER READINGS ON (DATES) / I GAVE ACCESS TO THE METER / I ASKED FOR A CORRECT BILL ON (DATE)].
What I am asking you to do
Cancel the charges for energy used and standing charges before [DATE 12 MONTHS BEFORE THE BILL].
Send me a corrected bill for the last 12 months only.
Refund any money already taken for the earlier period to [ACCOUNT / CARD / CREDIT ON MY ACCOUNT].
Pause collection of the disputed amount while you deal with this complaint.
Please treat this as a formal complaint under your complaints procedure. If it is not resolved within 8 weeks, or you send me a deadlock letter, I will take it to the Energy Ombudsman.
Yours faithfully,
