New research by Uswitch.com has found that more than 16 million households (56 percent) will have credit with their energy supplier at the end of this winter, totaling £3.4 billion. This is despite the expensive winter for energy bills and the cost of living crisis that has left some households forced to choose between heating and eating. Energy expert at Uswitch.com, Will Owen, advises consumers to check their credit balance and consider reclaiming any excess amounts.
