The new Labour Government has admitted that an extra 10,000 pensioners will be plunged into poverty following Chancellor Rachel Reeves's decision to effectively cut the Winter Fuel Payment for millions.

In a letter to the Work and Pensions Committee, Department for Work and Pensions (DWP) minister Liz Kendall revealed tens of thousands of older Britons will fall into relative poverty due to the up to £300 in energy bill support being means-tested.

Citing internal modelling, Kendall shared: "The latest modelling shows that compared to the numbers that would have been in poverty without this policy, it is estimated that in each year in question there will be an additional 50,000 pensioners in relative poverty after housing costs in 2024/25, 2025/26 and 2027/28, instead.

"The modelling also shows that an additional 100,000 pensioners are estimated to be in relative poverty after housing costs in 2026/27, 2028/29 and 2029/30.

"For all other measures of poverty, it is estimated that there will be an additional 50,000 pensioners in poverty each year from 2024/25 to 2029/30."

Earlier this year, Chancellor Rachel Reeves revealed that the up to £300 in energy bill support will be means-tested going forward instead of being made universal for older Britons.

The pensioners minister highlighted in her letter these figures "represent the change in the numbers in poverty as a result of the policy change only"

As such, the statistics are not reflective in what the overall figures will be for the year or in the years to come and should "not be added together or interpreted as cumulative data", Kendall emphasised.

Furthermore, the minister noted that this impact assessment does not take into account the impact of Pension Credit take-up since the initial announcement of the benefit's means-testing.

Prior to the policy change, all older people were able to claim Winter Fuel Payments once they reached state pension age.

Going forward, pensioners will now need to apply for Pension Credit to access the allowance, which is a means-tested benefit for those on low income administered by the DWP.

"As I outlined in my evidence, we are taking significant steps to encourage those pensioners who are entitled to claim Pension Credit to do so with the success of our campaign boosting applications by 152 per cent, and I will continue with this endeavour," Kendall added.

"For example, we have written to 120,000 pensioners in receipt of Housing Benefit who may also be entitled to Pension Credit to encourage them to claim.

"In the longer term, we are working to bring together the administration of Pension Credit and Housing Benefit, to ensure that pensioner households receive the benefits to which they are entitled."
