Your rights
You have a right to request a refund of any significant credit balance on your energy account. While suppliers may hold a reasonable buffer, particularly for seasonal usage, excessive credit should be returned. For active accounts, Octopus Energy allows you to request some or all of your credit if your account is up to date, has a meter reading within the last 14 days, the balance remains above £5, and the refund does not put your account into debt. If Octopus Energy refuses or delays your refund without good reason, you can escalate your complaint to the Energy Ombudsman, an independent body that resolves disputes between consumers and energy suppliers.
Step by step
- 1Check your account balance and refund eligibility: Log into your Octopus Energy account online or via their app to confirm your current credit balance. Ensure your account is up to date, you have a meter reading within the last 14 days, and the refund will leave at least £5 in your account without causing debt. Note the exact amount you wish to refund.
- 2Request the refund: If eligible, use the online account or app to request your refund. Most app refunds reach your bank in 1-2 days. If the online refund option is unavailable, contact Octopus Energy's team directly by email at hello@octopus.energy, stating your account number and the amount you wish to be refunded.
- 3Escalate if necessary: If your request is denied or delayed unreasonably, make a formal complaint to Octopus Energy. They must try to resolve your complaint within eight weeks. If they do not resolve it to your satisfaction within this period, or if you receive a 'deadlock letter', you can take your case to the Energy Ombudsman. You must escalate a deadlock letter case within 12 months of receiving it.
- 4Provide bank details and await resolution: Ensure Octopus Energy has your correct bank account details for the refund. If escalating to the Energy Ombudsman, expect a decision within 6 weeks, though complex cases may take longer. Once you accept the Ombudsman's decision, Octopus Energy must implement the proposed remedies within 28 days. If Octopus sends a final bill and is late refunding any remaining credit, they will pay £40 compensation unless the delay has a valid reason outside their control.
What they'll say, and your comeback
“We need to keep a buffer for your winter bills.”
Comeback, While a reasonable buffer is understandable, my current credit balance is excessive. Ofgem rules state that suppliers should not hold onto unduly large credit balances. My account is up to date, and I have a recent meter reading, so I require the surplus to be refunded, ensuring my balance remains above £5.
“Refunds can take up to 10 working days to process.”
Comeback, I understand there's a processing time. However, app refunds typically reach my bank in 1-2 days. For final bill refunds, if it takes longer than 10 working days without a valid reason, I am entitled to £40 compensation. Please confirm the exact date I can expect the funds.
What actually happens
In practice, most credit refunds from Octopus Energy are straightforward. If your account meets the conditions (up to date, recent meter reading, balance above £5 after refund, no debt), you can usually request a refund via the app or online, with funds arriving in your bank account within 1-2 days. This quick process resolves the majority of cases. More complex situations, such as large refunds after closing an account, might take up to 10 working days. If Octopus Energy delays a final bill refund beyond this, they owe £40 compensation. If a dispute arises, escalating to Octopus Energy's formal complaints process is the next step, which can take up to eight weeks. If still unresolved, the Energy Ombudsman can intervene, typically providing a decision within six weeks. Most consumers find resolution at the initial app/online request or after a formal complaint to Octopus Energy.
