More than two million customers have switched to small independent energy providers since 2010, new figures reveal.
Around 100,000 customers moved to smaller suppliers every month since November last year, according to Energy UK.
There were more than double the number of switches to independent energy providers last month compared to the same period in 2013.
Angela Knight, Chief Executive of Energy UK said: “Energy switching is now an established fact of life even though we are in the middle of summer when people normally take a bit of a break from shopping around for new suppliers and deals.
“The number of people moving to small suppliers has remained high and these companies have now gained a strong foothold in the market.”
Earlier this year the Government announced new systems to make it easier and quicker to switch suppliers are being developed.
