Home heating oil prices in Ireland: October 2026

Monaghan had the cheapest 500L price we found: €799 (159.8c a litre). The dearest county's lowest price was €845 in Limerick (169.0c a litre), a gap of €46 across the 26 counties with a price in the past 24 hours.

Over the past 30 days, comparing the same oil suppliers on both dates, the typical 500L price rose €57 (7.3%): from €785 on 12 September to €842 on 12 October. Over the past 90 days, the typical 500L price across counties rose €188 (28.9%): from €652 on 15 July to €841 on 12 October. Past prices do not predict the next move. A price alert emails you when your county reaches a price you choose.

It depends on the house, the boiler, the weather and how you heat, so a bedroom count is a poor guide. Work it out from your own tank: oil at the start, plus oil delivered, minus oil left at the end, over the same days. For example, a house using 10 litres a day would get about 50 days from 500 litres, and one using 5 litres a day would get about 100.

No. Citizens Information says the SEAI Better Energy Homes scheme does not cover replacing an oil or gas boiler, and the Warmer Homes Scheme has not fitted new fossil-fuel boilers since 1 January 2025. SEAI does pay €700 towards better heating controls for an existing boiler.

Less. On 6 October 2026, Budget 2027 cut carbon tax on kerosene from €63.50 to €48.50 a tonne until 2030, replacing the increase due on 14 October 2026. At €48.50, Revenue's kerosene rate is €122.83 per 1,000 litres, or 12.283c a litre: €21.55 less on 500 litres including VAT. Revenue had not published the date the lower rate starts when we checked on 9 October 2026.

The cheapest 500L price we found in each county ranges from €799.00 to €845.00, across 26 counties checked in the past 24 hours. Your own price depends on your supplier and address.

Not always. A bigger fill usually costs less per litre, but you pay more upfront and need room in the tank. Compare the total and the price per litre for each size.

The right fuel and amount, the total for your address including VAT and any delivery or payment charges, the delivery day, and access to your tank.

We only show a price we found in the past 24 hours for that county and fill size. If we have none, the county page still lists the oil suppliers who deliver there.

If your tank is low, order now and allow a few days for delivery. If you can wait, a price alert emails you when prices reach your target. The tank planner can help you work out when to order.
