Overview
- Around £240–£250 million in credit remains in roughly 1.9 million closed UK energy accounts, according to Ofgem and Energy UK.
- More than 90% of closed-account balances are returned automatically, Energy UK says, but missing customer information prevents some refunds.
- Ofgem rules require suppliers to issue a final bill within six weeks of account closure and to return any credit within 10 working days.
- Consumers are encouraged to check final bills in emails or letters, log into old online accounts, or contact former suppliers to recover funds.
- Energy UK advises keeping direct debits active until the final bill is settled to avoid leaving money unclaimed when moving or switching.
