Almost 15,000 households in Powys are due to receive the first cost of living payment from the Government, new figures show.
But the Resolution Foundation warned the Government has not provided enough support to those on low incomes who do not receive benefits, as people deal with spiralling energy prices and soaring inflation.
Department for Work and Pensions figures show around 14,100 households in Powys are eligible to receive up to £900 in cost-of-living payments.
They are among more than 8 million households across the UK who will receive the support.
Estimates have been rounded to the nearest 100 households.
The first of three instalments – worth £301 – is due to be made between April 25 and May 17 and should appear directly in people's bank accounts.
Those eligible include anyone who received any of the following benefits between January 26 and February 25 this year:
- Universal Credit;
- Income-based jobseekers allowance;
- Income-related employment and support allowance;
- Income support;
- Working tax credit;
- Child tax credit;
- Pension credit.
However, with consumer price index inflation currently at 10.1% and remaining stubbornly high, charities have warned some people will fall between the cracks as they deal with rising prices.
Lalitha Try, economist at the Resolution Foundation, said: "The Government’s cost-of-living payments will provide much-needed support for over 8 million UK households, and are rightly targeted at many of those who will need the most help.
"However, many families who are urgently in need of help will still fall through the cracks – such as those who are on a low income, but not receiving benefits."
Alongside the support payments is a £150 disability payment, which will be paid out to 6.7 million individuals across the UK this summer – approximately 15,000 of these are based in Powys.
A further £300 is due for pensioners in receipt of winter fuel payments later this year.
Mel Stride, Secretary of State for Work and Pensions, said the Government continues "to wrap our arms around the most vulnerable".
Ms Stride added that work is "the best route out of poverty", highlighting the work coach support scheme to help people boost their skills and progress in their careers.
Chancellor Jeremy Hunt said: "I know that times are tough, which is why a key focus of the Spring Budget was supporting people with the cost of living and helping people into well-paid work."
