Martin Lewis has issued a £400 warning to anyone who pays their energy bills in a certain way.

Hundreds of thousands of households have not redeemed vouchers which will take £400 off their energy bills this winter, leading to concerns that some might miss out on vital Government support.

PayPoint said only a little over half (53 per cent) of the 800,000 vouchers it has issued have been redeemed so far.

It means that households are so far missing out on around £27 million in support that would be paid by the Government.

Under the Government scheme, which was announced in May, households will get between £66 and £67 taken off their energy bill every month between October and April.

For households that pay via direct debit, or who have smart pre-payment meters, this money is taken off automatically.

But millions of households are on older pre-payment meters – and these people are instead sent a voucher which they have to redeem in a shop.

Martin Lewis warning to people on pre-payment meters

Money Saving Expert founder Martin Lewis shared a warning on social media.

He wrote: "Are you on a NON-SMART PREPAYMENT energy meter? If so there are reports today many people on these have not yet claimed their £66/mth winter energy help vouchers. If you're in that position, have you claimed, if not why not (maybe just not topped up yet after pre-loading?)".

Adam Scorer, chief executive of the charity National Energy Action, said: “One of the least surprising outcomes from the Energy Bills Support Scheme is that people on older pre-payment meters are most likely to miss out.

“They may not know that the scheme exists, be reluctant to open letters from suppliers, miss the email, or can’t print the voucher off.

“Having the support in place is, of course, vital. Making sure people can and do access it is just as important.

“The UK Government must learn this lesson for whatever comes after the Energy Price Guarantee.”
