Heating Oil Roscommon — Price Guide & Ordering Advice

Kerosene (home heating oil) prices in Ireland are driven by two things: the Brent crude benchmark and the EUR/USD exchange rate. When oil rises on global markets or the euro weakens against the dollar, your delivered price per litre goes up. This happens regardless of which county you're in.

Roscommon is served by the same regional supplier network as Galway and Mayo. Pricing is broadly similar across Connacht, though individual suppliers vary.

Prices can vary 5–10 cent per litre between local suppliers depending on delivery distance, order size, and demand. Comparing before you order is the single easiest way to reduce your annual heating bill.

April to July is typically the cheapest window. Demand drops after the heating season ends, and prices usually follow. Many people order in April and top up again in August — this avoids the peak season entirely.

October to December is peak demand — prices are highest and some suppliers get booked up. Emergency deliveries cost more and aren't always same-day. Order before you need to, not when you're running low.

The minimum order from most suppliers is 500 litres. If your tank holds 900 litres or more, filling it gives you a better unit price — the per-litre cost drops as the order size increases.

If you have neighbours with oil tanks, a shared 1,000-litre order can bring the price down further. Split the delivery, split the saving. Most suppliers are happy to accommodate this.

Never let your tank drop below 10%. Sludge from the bottom can block your boiler filter and damage the pump. Set a reminder to order when you hit 25% — that gives you time to shop around.

Single-skin tanks are still legal in Ireland. What matters is condition — no visible rust, no leaks, stable base, intact filler cap. Get it inspected by an OFTEC-registered engineer if it's over 15 years old.

Bunded tanks (a tank within a tank) are required near rivers, streams, or in certain flood-risk areas, and they're becoming the standard for all new installations. If you're replacing an old tank, go bunded — it's the right choice regardless of whether it's legally required for your location.

A 900-litre single-skin tank is the most common size for rural homes in the west of Ireland. Larger homes or those with older, poorly insulated walls may need 1,000–1,200 litres to cover a full winter.
