Short answer
The Energy Ombudsman — the free, impartial service that resolves disputes with energy suppliers in Great Britain. You go to it after complaining to Octopus Energy and waiting 8 weeks, or sooner if Octopus Energy sends a deadlock letter.
How to take a complaint about Octopus Energy to the Energy Ombudsman
- Complain to Octopus Energy first, in writing if you can, and keep the reference.
- Allow 8 weeks for it to be put right — or less if the supplier sends a deadlock letter saying it cannot do more.
- Register the dispute with the Energy Ombudsman online, by phone, email or post. It is free.
- You must escalate within 12 months of receiving the deadlock letter.
- Both sides send evidence within 14 days; the Ombudsman reviews it and makes a decision.
- If you accept the decision, the supplier has 28 days to carry out the remedy.
The Ombudsman can tell a supplier to take practical action — credit your account, cancel an account, change your tariff — apologise, or pay a financial award. It cannot punish or fine a supplier.
