The Sunday Telegraph | Why the end of the ‘Big Six’ hasn’t made power any cheaper

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.
