What went in

The charge and why it is wrong
Energy bill for the quarter to 30 June came to 612, about three times our normal 200. The bill is based on an estimated reading of 48,200. I submitted an actual reading of 44,180 on 28 June through their app and have the confirmation email. They billed the estimate anyway. Usage has not changed.
Account or reference number
Account 88-4471-02, bill number INV-2026-0630-9912
What correction you want
Rebill the quarter using my actual reading of 44,180 submitted on 28 June, and confirm the corrected amount in writing before taking any direct debit. If a payment has already been taken, refund the difference.

What came back

Subject: Incorrect estimated reading used on bill INV-2026-0630-9912, account 88-4471-02 This concerns bill INV-2026-0630-9912 on account 88-4471-02, for the quarter ending June 30, charged at 612. This is roughly three times our normal quarterly bill of around 200. The bill is based on an estimated reading of 48,200. I submitted an actual meter reading of 44,180 through your app on June 28, two days before the billing period closed, and I have the confirmation email for that submission. The bill was generated using the estimate instead of the actual reading I provided. Our household usage has not changed: same two people living here, no new appliances, nothing that would explain a jump of this size. I need the quarter rebilled using the actual reading of 44,180 submitted on June 28, and written confirmation of the corrected amount before any direct debit is taken. If payment has already been collected on the 612 figure, I need the difference between that and the corrected bill refunded. If this is not corrected within 14 days, I will dispute the charge with my bank.

When to use it

Use this when a bill or a charge is wrong and you need it corrected in writing. It states the specific charge, why it is wrong, what correction you want, and a real deadline, which is what turns a complaint into something with a next step.

Common questions

Should I pay the disputed amount while it is being sorted?
That depends on the contract and the sector, and it is worth checking rather than assuming. Withholding payment can affect your credit file or trigger late fees even when you are right. Many people pay the undisputed portion and say so in writing, which the message can state if you tell it that is your position.
Should I cancel the direct debit?
Be careful. Cancelling can put you in arrears if the dispute goes against you. Asking them not to take the payment until the dispute is resolved, in writing and with a deadline, is usually the stronger move and is what the example asks for.
Why does it include a deadline?
Because an open-ended request gets filed. A specific date creates a point at which you can escalate, and it makes the timeline clear if you later go to an ombudsman. Fourteen days is a common and reasonable window.
Does it know the rules for my sector?
This writes the letter, it does not give legal advice. It works from the facts and grounds you provide and does not know the rules that apply to your case. For anything with money or a deadline attached, check your rights with a source that does: Citizens Advice in the UK, your regulator or ombudsman, or a solicitor.
