The real cost of replacing a heating oil tank in Ireland (2026)

For a standard domestic swap-out — old tank drained, removed and disposed of, new tank supplied and fitted on an existing sound base — tank replacement starts from €1,400 including VAT. There is no fixed upper limit: the final figure depends on tank size, base work, pipework and access, and it is always confirmed in writing before we start.

Drain-and-remove-only (you're switching heating source and want the tank gone) starts at €380 and rises with access difficulty and residual fuel volume.

Three things move the number: tank size (1,200 L vs 2,500 L), brand (we fit Kingspan and Carbery only — both sit at the premium end for good reason), and base condition. A cracked or under-sized concrete base needs re-pouring or a proprietary plastic base, which adds €200–€500.

Access matters too. If the tank has to be crane-lifted over a house or wheeled 40 m down a side passage, that's a longer day on site.

Supply and delivery of the new bunded tank, drain-down of the old unit, removal and licensed disposal, base check or repair, reconnection of fill and feed lines, a fire valve at the boiler, commissioning and a written handover.

If any of those aren't in your quote, ask. Add-ons after work has started are the number one complaint homeowners raise about tank replacements.

A leaking tank isn't a wait-and-see situation. Kerosene reaching soil or a drain becomes an environmental incident with cleanup costs that dwarf any tank price. If you see weeping seams, rust runs or a persistent oil smell, get it quoted this week.
