Millions of people are owed refunds by their former energy company, according to the watchdog Ofgem. It said yesterday that the Big Six firms have kept more than £400m over the past six years from customers who have switched supplier or moved house.
Some 3.5 million former customers of British Gas, EDF Energy, E.On, NPower, Scottish Power and SSE are owed an average £58, the regulator said. Meanwhile, about 300,000 former small business customers are owed an average £680 each.
The watchdog has demanded that the large suppliers make sure money is returned to their former customers.
