Experts urge prepayment customers to check their post for the vouchers, which are only valid for 90 days
Half of £400 energy bill vouchers went unclaimed this month, as the Government fails to reach millions of homes in need of support through the winter months.
The majority of homes paying their energy bills by direct debit qualify for automatic rebates through the Government’s Energy Price Guarantee scheme.
However, for homes on older pre-payment meters, which require topping up via a key or card in a local newsagent or Post Office, the support arrives in the form of a voucher.
PayPoint, a meter provider, said that it expected to process 800,000 vouchers in October, worth £52.8m. So far only £27m has been redeemed, just half that level, it said.
