A once-off fuel allowance payment of €125 will be paid to recipients this week.
The measure was announced last month as part of the Government package to tackle the rising cost of living.
Fuel prices are one of the main drivers of rising inflation, while the war in Ukraine has also pushed costs higher.
Last month, the Government announced a €500 million package to help offset this burden on households.
As part of that, those already in receipt of the fuel allowance will get an extra €125 this week.
But with inflation at a 21-year high, political pressure is likely to remain on the Government to do more.
It is hoping for leeway from the European Commission to lower VAT rates.
Minister for Foreign Affairs Simon Coveney admitted this weekend however that the Government could not entirely mitigate the consequences of the war in Ukraine.
