How Co. Donegal compares with the national benchmark
The SEAI publishes a national average kerosene price as part of its domestic fuel cost comparison. It is a benchmark rather than an offer — nobody sells at it, and you cannot order from it — but it is the fairest way to say whether Co. Donegal is currently dear or cheap relative to the country as a whole.

Heating oil in Co. Donegal
Donegal has no natural gas network. Every household in the county heats with oil, solid fuel, electricity or a heat pump, and oil-fired central heating is the most common of them by a wide margin. Combined with a long and genuinely severe Atlantic heating season, that makes Donegal one of the heaviest domestic kerosene markets in the country.
It is also one of the hardest to serve. The county is large, the population is spread from Inishowen down to the Bundoran end, and roads into the Gaeltacht areas and the north-western peninsulas are slow. Delivery runs are correspondingly long. Households here tend to buy in larger volumes for that reason: where a 500-litre part fill is common elsewhere, a 900-litre or full-tank order is more usual in Donegal, both to reduce the price per litre and to avoid running low in midwinter.

Heating oil in Co. Donegal: common questions
How much is home heating oil in Donegal right now?
The cheapest kerosene quote we hold for Co. Donegal is €837.01 for a 500-litre delivery and €1,493.33 for 900 litres, from Certa, at 165.9c/L. That was recorded on 11 October 2026. Heating oil is not a regulated price and it moves daily with the wholesale market, so treat this as an indication of where the market sits rather than as a price you can hold a distributor to.
Which suppliers deliver heating oil in Donegal?
1 distributor in our data quotes for Co. Donegal: Certa. That is not the whole market — most counties also have local distributors who quote by phone and do not publish prices online, and it is usually worth ringing one or two of them before ordering. Our figures exist to tell you whether the price you are quoted is reasonable, not to be the only price you get.
Is it cheaper to order 500 or 900 litres in Donegal?
900 litres, by a clear margin. At the cheapest Donegal quote, 500 litres costs €837.01, so buying 900 litres in two 500-litre-rate portions would cost about €1,506.62 — against €1,493.33 for a single 900-litre delivery, a saving of roughly €13.29. The delivery itself costs the distributor much the same either way, so the bigger the order, the further that cost is spread. The counter-argument is cash flow: a part fill is easier to find in a week when the boiler is already running.
Why is the SEAI national average different from these Donegal quotes?
Because it is a different kind of number. The SEAI figure is a published national benchmark averaged across the whole market — it is not a quote, no distributor is offering to sell at it, and you cannot order from it. It is on this page for one purpose: to tell you whether Co. Donegal is currently dearer or cheaper than the country as a whole, and by how much. The distributor quotes above are real prices that were live on the date shown.
When is the best time to buy heating oil?
Earlier than most people do. Kerosene prices track crude oil and the wholesale refined market, and they also respond to demand: a cold snap sends every household in the county to the phone at once, which pushes prices up and delivery times out at exactly the moment nobody can wait. Buying in late summer or early autumn, before the first cold weather, is a better habit than buying in December, and it removes the risk of running dry on a week when the tanker is booked out.
