Research from Cornwall Insight was cited in The Sunday Telegraph’s article on energy bills over the decade. Data showed that families paid an average of £571 a year for electricity and gas in 1998, compared to £1,447 in 2018.
Further research showed that at the end of 2016, the cheapest tariff was £790 a year. After a series of supplier exits, this had risen to £864, having reached as high as £930.
Many suppliers could not understand how some new entrants could offer such low-cost tariffs. They helped them grow customer numbers but history has since shown this approach often led to poor customer service and consumer detriment.
