What this tool does

This interactive tool creates a formal complaint letter to your gas, electricity or water supplier when you have received an incorrect bill. It takes the key details about your dispute and formats them into a professional letter that references the appropriate industry guidelines.

The tool handles common billing errors like estimated readings when you have provided actual readings, charges for the wrong tariff, or bills that do not reflect meter readings you have submitted. Your finished letter will be ready to send by post or email.

When to use it

Use this tool when you have spotted a clear error on your utility bill and need to raise a formal complaint with your supplier. This might be because they have ignored your meter readings, applied the wrong rates, or charged you for usage that does not match your actual consumption.

It is particularly useful if you have already tried to resolve the issue through customer service without success, as a formal written complaint often gets escalated to a specialist team and creates a paper trail for any future disputes.

How it works

You provide your contact details, account information, and a description of what is wrong with your bill. If you have the correct meter reading, you can include that too. The tool then creates a structured complaint letter that clearly sets out your case and requests a corrected bill.

The whole process takes about two minutes, and you can choose the tone of your letter depending on how strongly you want to express your concerns. Nothing you enter is saved, and you do not need to create an account to use the tool.
