It is unacceptable that prepayment customers, who are often moved to a prepayment meter because they cannot afford their energy bill, pay more for their energy than direct debit customers. We recommend that Ofgem addresses this differential, for example by reinstating the Safeguard Tariff for prepayment customers, to ensure that they pay no more than direct debit customers for their energy. This would be a temporary measure while the Government consults on the operation of a social tariff.
