**Subject: Formal complaint regarding account 4429-1183**
Dear Sir or Madam,
I am writing to make a formal complaint about the billing on the above account between November 2025 and February 2026.
Over that period I was charged the standard variable rate despite having a fixed-rate agreement confirmed in writing on 12 October 2025, a copy of which I enclose. The overcharge amounts to £248.60. I have raised this by telephone on three occasions — 8 January, 22 January and 14 February — and on each occasion was told the account would be corrected within ten working days. It has not been.
I am asking for the account to be corrected to the agreed fixed rate, the overcharge of £248.60 to be refunded, and written confirmation that the fixed rate will apply for the remainder of the agreed term.
If I do not receive a substantive response within fourteen days I will refer the matter to the energy ombudsman.
Yours faithfully,
Jordan Avery

Frequently asked questions
- What is the correct layout for a formal letter?
- Your address, then the recipient's, then the date, then a subject line, then the salutation and body. Close with 'Yours sincerely' when you know the recipient's name and 'Yours faithfully' when you don't.
- Should I include a subject line?
- For anything that may be filed or forwarded, yes. It makes the letter findable later, which is usually why the letter exists.
- Can I keep a copy?
- The PDF is generated on your machine and downloaded straight to it. Nothing is uploaded, and drafts stay in your browser until you delete them.
