Money saving expert Martin Lewis has explained how "millions" of people can save over £300 on their energy bills.
The MoneySavingExpert.com founder was speaking on his own ITV1 show, The Martin Lewis Money Show, on Thursday night - as you can see in the video above.
EDF Energy customers on the standard tariff will be able to capitalise on a deal that will save them £320 a year if they switch tariffs.
Customers will only be able to do this via price comparison sites.
The cash-saving guru was responding to a viewer who had emailed in to thank him for his advice.
"EDF customers, if you're on its standard tariff, which most of you are, there's a deal that is about £320 a year cheaper," he said.
"It's only available via comparison sites, you can't go direct.
"It's still EDF, so the same gas, same electricity, same safety, same customer service, the only thing that's different is the price.
"£300 a year cheaper, no-brainer, so get yourself on a comparison site and shift to that tariff if you're on a standard tariff with EDF.
"Huge savings, that's millions of people eligible for that, it's just burning money if you don't."
The Martin Lewis Money Show airs on Thursday night from 8:30pm.
