Heating oil tank FAQ

Straight answers to the questions Irish homeowners ask us every week — bunding, OFTEC, costs, contamination and disposal.

How much does it cost to replace a home heating oil tank in Ireland?

Tank replacement starts from €1,400 supplied and fitted, with no fixed upper limit — the final price depends on tank size, brand, access and whether the base needs work. A drain-and-remove-only job starts at €380. We always quote in writing before any work begins.

Do I legally need a bunded tank?

For new domestic installations in Ireland, a bunded (double-skin) tank is required where the tank is within specific distances of a building, boundary or drain, per OFTEC guidance. In practice almost every replacement we do today is bunded — it's safer, cheaper to insure and future-proofs your home.

How long does a tank replacement take?

A typical domestic swap-out is done in a single day. That includes emptying and removing the old tank, prepping the base, siting the new tank, connecting the fill and feed lines, and testing the system. Base repairs or awkward access can push it to a day and a half.

My oil looks cloudy or my boiler keeps cutting out. What's wrong?

That's usually water and sludge in the bottom of the tank feeding microbial growth. It clogs filters and damages burners. We drain the contaminated fuel, filter what's recoverable, dispose of the sludge and inspect whether the tank can be safely refilled.

Can you remove an old tank I'm no longer using?

Yes. We empty the residual oil, degas the tank, lift it out (crane or manual depending on access), remove associated pipework if you want, and take the tank away for recycling under proper waste transfer documentation.

What tank brands do you fit?

We supply Kingspan and Carbery only — the two highest-quality manufacturers we stand over. Range covers 900 L up to 2,500 L, horizontal and vertical, for domestic and light-commercial use.

Do you work on kerosene, gasoil and HVO?

Yes. Home heating kerosene is the most common in Ireland, but we also handle gasoil (red diesel / marked gas oil) and HVO-derived heating fuels where the boiler and tank are compatible.

Do you cover my area?

We work across Leinster, the Midlands and surrounding areas. Dublin, Meath, Kildare, Wicklow, Carlow, Kilkenny, Westmeath, Laois, Offaly and Longford are our busiest counties — see the area pages. We may also travel further for planned installs by arrangement.

What if my tank is leaking right now?

Ring us. A live leak is an environmental incident: kerosene reaching soil or a drain triggers reporting and clean-up obligations. We can usually be on site fast, contain the spill, pump out remaining fuel and quote the replacement while there.

Do you handle the paperwork and old-tank disposal?

Yes. We're set up as a waste carrier for the old tank and any contaminated fuel or sludge, and we hand you the waste transfer documentation. No skip needed, nothing left behind.

Still not sure?

Send us a photo of your tank and we'll tell you what's going on — no obligation.
