Households on prepayment meters only have exactly one week left to cash in their energy support vouchers.
These energy vouchers, which were given through the Government's Energy Bill Support Scheme last year, will expire on Friday, June 30 at 11:59pm.
After this date you will not be able to use the vouchers to get money off of your energy bills.
The Energy Bill support scheme gave every household in the country £400 off their energy bills from October 2022 to March 2023.
This was done with monthly discounts worth £66 and £67 which were given directly through energy suppliers.
Those on direct debits and smart prepayment meters received the payments automatically.
However, those on non-smart prepayment meters were sent vouchers by post or email and have had to take them to a post office or PayPoint vendor in order for the discount to be credited to their meter.
According to recent data, around 1.7million vouchers - worth around £10million have yet to be redeemed.
According to a report by MoneySavingExpert.com, energy firms have been ordered to return any unused funds immediately after the end of the scheme.
This means there is no way you can get these vouchers after the deadline.
How to claim the energy support voucher
Many of the energy support vouchers were sent by suppliers to those eligible by email, text or post.
They then needed to be taken to a local PayPoint store or a Post Office to be credited onto prepayment meters.
The vouchers must be redeemed within 90 days of their issue date - if your voucher has expired, then you will need to contact your energy provider to get a new one issued.
If you have not received your energy voucher, then you should contact your supplier directly over the phone, by email or in a letter.
You can find out the best ways to contact your supplier on their website.
If you are struggling to use the voucher, the Government says you should contact your electricity supplier immediately for help.
According to the rules, you can use two backdated vouchers in the same month.
If you're storing your vouchers to redeem later, you should be aware that most meters can only hold up to around £250 of energy credit at a time.
