To whom it may concern,

Re: Back-billing complaint

I am writing about a problem with how my account has been billed. This problem falls under Ofgem's back-billing rules.

I have still not received my first bill at this address, despite contacting you several times to ask for one. I requested a bill on 3 April, 10 May and 7 June and moved into my new home on 10 March. I have spoken to you on the phone on several occasions and you have not issued a bill. I provided meter readings on the day I moved into the property and each time I spoke to you. I am unhappy with the level of customer service you have given me.

The Ofgem back-billing rules say I should only have to pay for 1 year’s energy use if I haven’t received an accurate bill for over a year. Please make sure that the Ofgem back-billing rules are applied to the balance on the account.

Please explain why you haven't issued a bill and what you are able to do about the poor level of customer care I’ve received.

Please respond to my complaint in writing within 10 working days. If you fail to respond in this time, I will consider taking the matter further.

Thank you.

Yours faithfully,

Sam Hoolin
