A new cost of living disability payment will be paid out to roughly six million people from September 20.
The £150 one-off payment will be sent to help those on certain disability benefits tackle the rising cost of living.
The Department for Work and Pensions (DWP) said the "vast majority" of eligible claimants should get the cash by the start of October.
In its latest update, the DWP said: “Those who had confirmed payment of their disability benefit for 25 May are expected to be paid shortly after the payment window opens.
“For those awaiting confirmation of their disability benefits on 25 May, or who are waiting to be assessed for eligibility to receive disability benefits, the process may take longer but payments will still be automatic.”
The one-off lump sum payment will go to those who are already receiving any award level for one of the following:
- Attendance Allowance
- Constant Attendance Allowance
- Disability Living Allowance for adults
- Disability Living Allowance for children
- Personal Independence Payment
- Adult Disability Payment
- Child Disability Payment
- Armed Forces Independence Payment
- War Pension Mobility Supplement
Those getting a qualifying disability benefit from the Ministry of Defence (MOD) and a qualifying disability benefit from DWP, will only receive a Disability Cost of Living Payment from DWP.
And the lump sum will be paid per claim, which means if two people from the same household apply for the benefit payment, they will each get separate payments of £150.
Speaking of the new benefit, Chloe Smith, Minister for Disabled People, Health and Work, said: "We know disabled people can face additional costs, which is why we are acting to help reduce the financial pressures on the most vulnerable.
"This £150 disability payment is on top of the £1,200 most low-income benefit claimants will also receive and alongside wider support targeted at disabled people, including help with transport and prescription costs."
Smith has also urged people to check the Help for Households site on GOV.UK to make sure they are getting all the support they are entitled to claim.
The payment will be released to millions shortly after new Prime Minister Lizz Truss announced households on the Ofgem energy price cap will have their bills frozen.
Under the Government's new 'energy price guarantee' scheme, the average UK home will not pay more than £2,500 a year for energy from October 1, 2022.
The Prime Minister said: "We are supporting this country through this winter and next."
