According to energy regulator Ofgem, the number of UK households switching their energy providers rose by 15 per cent in 2015.
Official figures showed that 6.1 million gas and electricity accounts had been transferred during the year, around 800,000 more than in 2014.
Ofgem’s Rachel Fletcher, welcomed the news, claiming the level of competition in the market was improving. She said: “It's encouraging to see switching levels at their highest level for four years.”
The findings come as the ‘big six’ energy companies have all cut prices for their gas customers this year by a minimum of 5.1 per cent, however there has been no reductions to electricity tariffs.
The Competition and Market’s Authority (CMA) is due to publish its report on the energy market next month, and has said that householders could save up to £234 annually by switching providers.
Anne Robinson, from the price comparison site Uswitch, has claimed that consumers had been generating even larger savings, citing figures which suggest in the last three month of 2015, the average switcher’s dual fuel saving was £337.
The CMA will release its provisional report in March, with a final report expected on 25 June.
