Up to 40% of Irish households could be facing fuel poverty this winter.
New research from the ESRI found 29% are struggling because of high energy costs, with one in 10 currently in fuel poverty.
Between January and April of this year, homeowners have seen their energy bills increase by an average of €21.27 cent per week, that rises to €38.63 cent when motor fuels are included.
Co-author of the report and ESRI economist Dr Barra Roantree specifically targeting measures are more effective than indirect cuts to tax.
He's recommending the government extend the fuel allowance, pay a Christmas Bonus style payment to those on lower-income this autumn and to couple it with the electricity.
"Rising energy prices are having a substantial impact on households, many of whom were already experiencing energy poverty or deprivation," Niall Farrell, who helped author the report, explained.
"Our research finds that, on average, these changes are more burdensome for lower-income households, rural households and those at risk of poverty. This is because energy expenditures tend to comprise a larger share of income for these households."
