More than 3.8 million customers switched energy supplier in the first half of the year, around a million more than the same period last year.

In the first half of 2016, around 1.6 million domestic customers switched gas suppliers and 2.2 million domestic customers switched electricity suppliers.

The data, published by Ofgem, also showed that 66% of domestic customers are still on expensive standard variable tariffs. The average standard variable tariff of the larger energy suppliers as of 28 July 2016 was £1,066. The cheapest tariff available on that date – a one year fixed tariff – was £758, a saving of £308.

Small business, consumers, and corporate responsibility minister Margot James said: “Thanks to the government’s action, it’s easier and quicker to switch than ever before. The number of suppliers has more than tripled since 2010 and it is great to see more people have already taken advantage this year by switching and saving money on their bills.”
