Dear Sir/Madam,

Re: Complaint against <Company Name>

I have recently received a bill from you which estimated a significant increase in my annual costs. Last year you estimated my costs would be <last year’s estimate>. This year the cost is <this years estimate>. This is an astonishing increase which I can’t afford and I would like to raise a formal complaint.

Please can you provide the basis on which the figures are calculated including readings, calculation of annual kWh, rates for usage and daily charges. Until I have received these and responded please keep the complaint open and do not close it until I confirm it can be closed.

I understand you have 8 weeks to resolve my complaint before I can go to the energy ombudsman. If we haven’t agreed a resolution about my complaint before the 8 weeks have lapsed, I understand you'll issue me with a deadlock or 8 week letter which means I can then take my complaint to the energy ombudsman.

Please respond to my concerns, including any other information you feel would help resolve this complaint.

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

Thank you.

Yours sincerely,

<Your Name>
