Rocio Concha, Which? Director of Policy and Advocacy, said: "The cost of living remains consumers' number one priority, yet Which? has heard concerning stories of consumers having their energy direct debits miscalculated or increased by huge amounts, while our research shows many customers are struggling to understand their bills and pricing. "It's encouraging to see the regulator taking action over poor performance and Ofgem should not hesitate to impose penalties on any suppliers that fail to make the necessary improvements. "At a time when consumers are paying more than ever before for energy, the regulator must also work with government and suppliers to explore ways of using data proactively to offer targeted support to those in most need of help before they have to turn to debt charities. "Which? will seek to work with businesses in energy and other key sectors to find more ways to support consumers through the tough times ahead."
