Craig Salter, Energy Spokesperson at CAS:
“Energy customers should never have to pay for the mistakes of suppliers, and it is right that these customers will now be refunded.
“Accurate billing is essential to ensure that energy customers don’t end up paying over the odds for their energy. It is a key element of delivering good service.
“The move from Ofgem to order suppliers to refund customers is welcome, but energy companies must take action to ensure that mistakes like this are not repeated in the future.”
