The number of consumers living in households that are in debt to their energy supplier has exceeded 5 million people, Citizens Advice has revealed. A survey of over 4,000 people conducted towards the end of 2023 on behalf of the consumer watchdog revealed that more than 2 million people across Great Britain will self-disconnect this winter because they cannot afford to top up their prepayment meter (PPM). Citizens Advice is warning that existing support is “simply not going far enough” and that a long-term plan to tackle spiralling energy debt is now essential.
