Money Saving Expert Martin Lewis says people across the country could get £140 from the Government towards their heating bills.
Speaking on the Martin Lewis Money Show on ITV on Thursday night he said many people may be unaware that they qualify for a discount.
He said: "Are you due a Warm Home Discount? "This is £140 credit that goes towards your energy bill.
"It's automatic if you receive a guaranteed element of pension credit but if you are on certain benefits (income support, jobseekers, and some people on universal credit) you will need to apply to your energy firm to get it."
Martin says that not every energy firm uses the scheme but many of the bigger suppliers do, reports The Star.
He said: "If you're someone who qualifies for Warm Home, there are so many big firms that do it with relatively cheap prices.
"I'd go to a firm, the cheapest firm that offers Warm Home discount, most comparison sites will show you that."
He warned that sometimes you have to apply for a deadline and there can be caps on the number of customers given the discount.
Martin then outlined the help available for people really struggling financially who have to choose between paying off energy bills and eating.
In England and Wales, it's Simple Energy Advice, and there's also Home Energy Scotland and NI energy advice.
