An extra 200,000 pensioners will get money off their energy bills this winter, the government has announced.
Worth £140 per household, the Warm Home Discount scheme has been expanded to include everyone who receives the Pension Credit Guarantee, the Department of Work and Pensions has announced.
It said it expects around 1.4 million of the 1.7 million eligible households to take up the subsidy.
The scheme, paid for by the UK's energy companies including the Big Six firms, was first introduced in 2011 and is expected to cost £315 million this winter.
The vast majority will receive the discount automatically and won't have to do anything, while households that think they should be eligible for the scheme but don't claim Pension Credits should contact their supplier to see if they qualify for a discount.
Pensions minister Steve Webb said: "It is this coalition government's mission to build a fairer society, and ensuring our poorest households get the support they need with their energy costs is a key part of that.
"As we approach winter, no-one should have to go without heating because they can't afford the bills. That's why we have significantly extended the Warm Home Discount scheme - and increased its value – to give people peace of mind that they can keep their homes comfortable throughout the coldest months."
Trade body Energy UK said: "With winter round the corner, suppliers' schemes are already open for applications. Get in touch with your supplier or call the Home Heat Helpline on 0800 33 66 99 to see what help is available."
