Irish households face steep winter fuel costs as storage levels drop

Fuel costs for Irish consumers have risen sharply as winter approaches and energy storage levels fall below last year's marks.

EU energy ministers met on Thursday to address the rising costs and supply security. The European Union is entering the heating season with storage at 75 percent of capacity, down from 83 percent a year ago. EU Energy Commissioner Dan Jorgensen described the situation as very serious. He warned that while a supply crisis is not immediate, affordability is a critical issue for households and businesses.

Wholesale gas prices briefly reached €100 per megawatt hour on Wednesday, the first time since December 2022 that they hit that level. Current prices are trading at about three times the levels seen before the conflict in Iran. Electricity costs have also climbed. According to Central Statistics Office data, wholesale electricity prices nearly doubled over the past year. In September alone, wholesale prices rose nearly 7 percent month on month, while energy fuel costs jumped almost 11 percent compared to August.

Motorists are paying significantly more at the pump. On Thursday, the average price for a litre of diesel was €2.14, and petrol averaged €1.99. In August, those prices were €1.92 for diesel and €1.84 for petrol. Compared to February, when both fuels cost about €1.70 per litre, drivers are now paying up to 45 cents more for diesel. For a typical driver covering 17,000 kilometers annually and using 1,100 litres of fuel, this increase adds roughly €500 to yearly costs. These figures reflect current prices with temporary tax cuts in place; without those reductions, diesel would cost approximately €2.50 per litre.

Home-heating oil has seen the most dramatic increase. The average price for 500 litres was €833 on Thursday. That compares to €790 in September, €590 in early July, and €490 in February before the Middle East conflict escalated. Approximately 700,000 homes in Ireland rely on heating oil. A standard three or four-bedroom house uses between 1,500 and 2,000 litres per year, meaning many households will spend well over €1,000 more than they did in early 2026.

The price hike is driven partly by global oil markets, where Brent crude sits around $114 per barrel. However, a reduction in refining capacity in the Middle East has also contributed. Many refineries there have been damaged or bombed, limiting the ability to convert crude into petrol and diesel even when crude supply is available.
