Prepayment meter customers have until the end of the day to claim vouchers worth up to £400 to help with their energy bills.
The UK Government discount vouchers will expire at 11:59pm on Friday 30 June, so customers will need to load the money on to their meters before the deadline in order to benefit.
More than £100 million of Energy Bills Support Scheme vouchers are still yet to be claimed that were paid out between October 2022 and March 2023.
Any household with an electricity supply in Scotland, England and Wales is eligible for a £400 discount, with those in Northern Ireland eligible for £600 under the Northern Ireland Energy Bills Support Scheme.
The discount was sent automatically to those paying by direct debit, with six instalments of £66/67 sent each month over the winter.
People on traditional prepayment meters were due to receive vouchers by text, email or post which they can redeem when they top up at the usual point.
Customers need to visit a post office or PayPoint with their Energy Bills Support vouchers and identification by June 30. Any lost, missing or expired vouchers can be reissued as long as they are redeemed by the last day of this month.
Those with unclaimed vouchers are urged to contact their electricity supplier as soon as possible.
If you have been storing up your vouchers to redeem all in one go, it's worth noting that most prepayment meters can only hold up to around £250 of energy credit at a time.

Cities of London and Westminster – 44%
