Pensioners will start receiving up to £600 in their bank accounts from today to help with their utility bills.
More than 11.6 million pensioners will receive the winter fuel payment over the next two months.
This year’s payments have been boosted with an extra £300 per household pensioner living costs payment.
The vast majority of payments will be automatic, and anyone who has not received theirs by 13 January should contact the state’s Winter Fuel Payment Centre.
Work and Pensions Secretary Mel Stride said ministers “want to do everything we can to support pensioners, who are often most vulnerable to higher costs”.
“That’s why we’re giving all pensioner households an extra £300 on top of their winter fuel payment to heat their homes and stay warm this winter,” he said.
“This extra payment is just one part of the wider package of support we are delivering to help with rising bills, including the biggest state pension increase in history.”
The payment will appear with a reference starting with the person’s National Insurance number followed by “DWP WFP” for people in the UK, or “DFC WFP” for people in Northern Ireland.
Meanwhile, families claiming elderly benefits such as tax credits should also start receiving their second the cost of living payments from today.
It will be paid automatically between today and next Wednesday as part of the Government’s £37 billion cost of living package.
The £324 payment, the final part of the £650 announced by Rishi Sunak earlier this year, has already been paid to most Universal Credit claimants since 8 November.
Over seven million payments of £324 have been made, including to pensioners receiving Pension Credit.
The average pension credit is worth more than £3,500 a year and for those yet to claim there is still time as claims can be backdated by up to three months.
To ensure that a claim falls within the waiting period, pensioners are encouraged to apply as soon as possible, and no later than 18 December.
An online pension credit calculator is available to help check eligibility and get an estimate of likely premiums.
It is now the turn of those who have not yet transferred to Universal Credit.
HMRC’s Angela MacDonald said: “This second cost of living payment will provide further financial support to eligible tax credits across the UK.
“The £324 will be paid automatically into bank accounts, so people don’t have to do anything to receive this extra help.”
With this payment, over eight million households will have received a cash boost by 30 November.
The first payments were made to eligible families in July and September.
Additional living expenses support, due next year, was announced by Chancellor Jeremy Hunt in his latest fall statement.
That includes a further £300 for pensioners, £900 for households on means-tested benefits and £150 for those on disability benefits.
It was also confirmed that pensioners will get an increase of 10.1% to the national pension from April, after Mr Hunt confirmed the triple lock was protected.
The full new state pension is currently £185.15 per week, so a 10.1% increase would push it to £203.85.
For those on the old basic pension, who reached pension age before April 2016, it means an increase from £141.85 to £156.20.
The triple lock is normally used to calculate the increase in the state pension, but was temporarily suspended due to the distorting impact of the pandemic.
