Martin Lewis issued a stark warning to the Chancellor during the final instalment of his Money Show on Tuesday night.
Regulator Ofgem has confirmed it is increasing its price cap by a staggering 54%, which will see most bills rise by £693.
The price cap will surge from £1,277 to £1,971 from April 1 - while prepayment customers will be worse hit, with a jump of £708 from £1,309 to £2,017.

Mr Lewis spoke of his upset as he said he has been inundated with requests from people asking what they can do to lower their bills.
In most cases, the answer is not much.
While the April price hike is at the forefront of most consumer's minds, things could be about to get even worse.
Showing a graph of energy prices, Martin pointed to part of the chart where a steep incline began.
He said: "We are now one month into the review period that will set October's energy price cap.
"[That's] this bit, February, where it has gone really high.
"Based on the way it has been so far, I hate having to say this, genuinely, it really upsets me even thinking about it...
"That means the price cap in October, if things don't change rapidly, is going to be for someone with typical bills probably over £3,000 a year which is just unaffordable."
Turning to the camera, he then issued a plea directly to the chancellor, Rishi Sunak - ahead of the spring statement in two weeks' time.
He said: "The Chancellor, you've got a spring statement on the 23rd March, you're going to have to do something to prevent this because it's just too bad to think about."
Taking to Twitter, viewers at home agreed with him.
thriftychap said: "The energy market is insane at the moment and there are no real answers to save money like there used to be.
"The Government HAS TO step in. People cannot afford £3k a year to heat their homes."
Laura Alice said: "It’s actually insane we’re all just supposed to jump to this."
Dan Langshaw said: "Energy bills rising is so scary, how can they increase so much when the living wage doesn't increase with it? We cannot afford to live at this point."
