Rising energy and fuel costs in Ireland

In mid-October 2026, the Irish government implemented tax relief to mitigate rising energy costs for households. Following the Budget 2027 announcement, the carbon tax on home heating oil was reduced to €48.50 per ton of CO2 from a projected €71. Finance Minister Simon Harris noted that energy expenses represented the “most acute area of pressure” in household budgets, prompting the reversal of previous tax increases.

By late October, pressure on Irish households and businesses intensified due to rising wholesale oil and natural gas prices. These increases are linked to geopolitical conflicts in Iran, Ukraine, and Yemen, alongside lower European energy storage levels compared to the previous year. Wholesale gas prices have reportedly reached approximately three times their levels prior to the conflict involving Iran.

While consumers on fixed-term plans may have temporary protection, those on variable tariffs face greater exposure to market fluctuations. For the business sector, energy expenditure remains a major concern, with the Central Bank of Ireland projecting energy-price inflation could reach 5.8% in 2027.
