I congratulate my hon. Friend on securing the debate. Does this not speak to a need for wholesale reform of how people are charged for and pay for their electricity? He is right that customers who pay by direct debit build up significant credit balances, and the energy companies can earn interest on that, but customers who pay by prepayment meters are paying up front for energy that they have not
used, and they often pay a higher premium and higher standing charges. The people who can least afford it, which is often customers on prepayment meters, are paying the most. This is another injustice that has to be resolved.
