Comparison website energyhelpline has released the results a survey revealing that a third of UK households, who have stuck to the same supplier for at least five years, have spent £18.7bn more than they needed to. For the 15% of households who have not switched to a cheaper supplier for between five and 10 years, that equates to a loss of between £1,000 and £2,000. The 7% who have remained loyal for 10 to 15 years have lost between £2,000 and £3,000 and the 10% who have stayed with the same supplier for longer than 15 years have lost at least £3,000 each. The website warned that remaining loyal to one provider risks an overall rise in energy prices.
