More than 11million households across the country are overpaying on their energy bills and could save £280 a year - according to Money Saving Expert Martin Lewis.
A simple switch which should take just a few minutes could see you cut almost a third of the cost of your gas and electricity, reports MEN.
Appearing on This Morning, he said: "Eleven million are certainly overpaying, but it’s likely even more can save and everyone should check now, as in the last few weeks the prices of the cheapest energy deals have dropped even further.
"People often think energy companies have one price. They don’t. They can have lots of different tariffs.
"To prove the point, those on British Gas standard tariffs right now are paying £1,177 a year – roughly the rate of the price cap.
"Yet British Gas has another tariff at around £900 a year and it’s fixed so you know the price won’t rise.
"So it’s £280 a year cheaper, same gas, same electricity, same safety and same service – just a different price. And most existing customers are eligible to get it too.
"And those willing to move company can save even more, the cheapest deals on the market are currently around £830 for typical usage. So move to that and you could be paying £350 a year less.
"It’d be more accurate to say you could save 25 per cent to 30 per cent by switching, but doing it in money terms shows the impact more."
