How to dispute an energy bill without sending a vague complaint
The best disputes are narrow. Pick the exact billing error, attach evidence, ask for a specific correction and keep the escalation route clean.

| 4. Formal complaint | Use the template if the supplier does not answer the actual issue. |
| 5. Escalation | Use Ombudsman pages after deadlock or the required complaint period. |

Frequently asked questions
Should I call or write?
Write when possible because the evidence and wording are easier to prove later.
Can I dispute only part of a bill?
Yes. A narrow partial dispute is often clearer than challenging everything.
What if the supplier says the bill is correct?
Ask for a line-by-line explanation tied to the readings, dates and tariff rates.
