He said: “Politicians don’t want to admit competition hasn’t worked. The public want price controls or renationalisation of energy firms.”
Martin spoke out after Mr Cameron urged families to move away from British Gas after its 9.2 per cent price hike last week.
He said: “I’ve ranted against politicians yelling switch for a long time. It’s a dangerous thing to do.
“What the Prime Minister said worried me a lot. The worst time to switch is in the middle of price rises.
“Two of the big six have hiked prices. The rest will follow. Do a comparison now and the cheapest will be providers who haven’t raised prices yet. It’s out of the frying pan into the fire.”
Instead Martin, founder of moneysavingexpert.com, urged customers to “get their own back” on energy giants by going for a fixed deal guaranteed not to rise for one to four years.
“If we all fixed we would screw their market model. That is the way to get your own back on the big companies,” he added.
“Someone with a bill around £1,400 before the hikes could save £250 by going for an 18-month fix and a guarantee of no hikes. Or they could save £80 a year and lock in for four winters.”
Martin backed Labour’s plan, but added: “If you want to freeze prices, you should announce it the day before you do it, not years in advance.”
