The Energy Advice Line has welcomed the findings of a top-level probe that has found consumers can save around £200 a year by switching energy supplier.
But Julian Morgan, managing director of the price comparison, switching and advice service for energy users, said it was crucial for the government to work out why some consumers were failing to switch, thereby losing out on savings.
An analysis of energy bills by the Department of Energy & Climate Change’s (DECC) Domestic Fuel Enquiry has found that 13.5 million households in the UK are losing out on a total of £2.7 billion by staying loyal to their supplier.
