Homeowners in Ireland are facing a significant surge in home heating oil costs, witnessing a sharp rise over the past year. As of September 2026, filling a standard 1,000-litre household tank costs €1,443.88 on average. This marks an increase of €534.64 from the same time in 2025, when the average cost was €909.24, reflecting a 59% rise in just one year.
This steep increase in heating oil prices is largely attributed to disruptions in the global oil supply chain, primarily due to ongoing conflict in the Middle East. Ireland’s heavy reliance on kerosene for home heating has made it particularly vulnerable to these market disturbances. Additionally, kerosene’s use in aviation sectors has exacerbated supply pressures, further influencing prices.
As the colder months loom, many households are in a rush to replenish their oil tanks, often shopping around to find the most competitive rates among different suppliers. In response to the escalating prices, consumers are opting to buy smaller quantities or delay purchases altogether, hoping for a potential decrease in prices.
The dramatic rise in heating oil expenses has spurred renewed demands for government intervention to address and potentially mitigate these costs. However, industry representatives emphasize that pricing is primarily driven by global market forces, with fluctuations occurring frequently. They argue that suppliers, who operate with limited stocks, are compelled to purchase oil based on the prevailing market prices, leaving little room for profiteering.
