Speaking on Good Morning Britain, Martin, 48, discussed the new plans and explained what they will mean for customers.
Discussing the market as it stands at the moment, he said: “Politicians want a market that is competitive.
“This means if people want to pay less, they have to switch as there is no price regulation, so there needs to be a big difference between cheapest and most expensive.
“This system accepts some people will pay much more than others, and the scandal is loyal customers are paying the most.”
Revealing how a price cap will help customers, Martin continued: “The new rules will allow Ofgem to impose a price cap if it wants to and this will be the absolute most companies can charge. Ofgem don’t have this power at the moment.
“There would be a top price beyond which they can’t go, but there would be no rules on how low they go, so companies could still be competitive if they wanted to.”
However, Martin pointed out there is still some time before the new rules come into force.
He said: “But this doesn’t come into play for another year, so – winter is coming, now is the time to switch.
“Relying on the government to protect you in a switching market isn’t a great idea, so you have to do it yourself and make sure you are on a the best tariff.
“Use a switching service and make sure you use one that doesn’t hide the cheapest deal.”
Switching is a subject Martin is passionate about, and he has spoken extensively on it in the past.
During an appearance on This Morning last month, he explained the best way to switch, and said: “It only takes minutes to find your cheapest deal and then it’s switched over in 17 days.
“Those who worry about switching, don’t – it’s the same pipes, gas, meter, safety – you don’t lose supply – the only difference is price and customer service. And there’s no break in supply when you do switch.
“As your cheapest depends on where you live and what you use, there’s no one winner.”
Martin noted the cheapest is almost always a small provider you haven’t heard of, but he explained how to get around this for those nervous to sign up with an unknown company.
He said: “The huge encouragement given for new entrants to the energy market is actually putting many off switching. And to an extent there’s good reason. The energy market is swamped with new firms, and often at launch they offer super-cheap deals to build a customer base; yet feedback is limited or poor.”
