More than 1,000 Ukrainian refugees over retirement age who are eligible for this financial assistance are benefiting from it. The payment is designed to support low-income people with top-ups, as well as open up eligibility for other aid.
This includes free TV licenses for over-75s, council tax help and free NHS dental care.
The government has introduced emergency legislation to help people arriving from Ukraine.
This means that these refugees will not be subject to the habitual residence test.
If this support was not introduced, the government says individuals would have to wait up to three months before being able to collect income-related benefits.

People who have £10,000 or less in savings and investments will not be affected by the pension credit.
However, the government explains: “If you have over £10,000, every £500 above £10,000 counts as £1 of income per week.
“For example, if you have £11,000 in savings, that counts as income of £2 a week.”
Claims for pension credit can be made up to four months before a person reaches the legal retirement age.
They will need to provide details of their income, savings and investments, as well as their national insurance number.
Finally, Brits will also need to provide bank details for a payment to be processed.
More than 1.4 million pensioners across Britain currently receive pension credit.
The government said use of the payment was at its highest level since 2010.
