As of January 1 the average energy bill is on course to rise by £94 (five percent) a year, pushing already stretched households to the brink.
The energy price cap had dipped to £1,834 a year in October, but will increase to £1,928 a year in 2024.
Following the news, charities have warned the most vulnerable will be the hardest hit.
Gillian Cooper, director of energy at Citizens Advice, said: “Prices going up during the coldest part of the year will make life harder for millions of people struggling to pay their bills.
“We’re already helping record numbers with energy debt and we’re seeing more people than ever who can’t afford to top up their prepayment meter.
“The Government missed the opportunity to announce extra support for households who desperately need it this winter.
“The lack of action means far too many households will now be forced to choose between heating and eating this winter.”
