Oil tank replacement cost in Ireland
Irish installers and quote sites put a replacement 1,000 litre oil tank, fitted, at about €800 to €1,200 for single-skin and €1,200 to €2,500 for bunded. Removing the old tank or rebuilding the base can add a few hundred euro. No official or independent body publishes these prices, so the figures here come from businesses that sell or fit tanks. We checked them on 23 October 2026.

What a fitted replacement costs
QuoteHub, an Irish quote-comparison site, lists these typical 2026 prices:
- replacing a 1,000 litre single-skin tank: €800 to €1,200;
- a 1,000 litre bunded tank: €1,200 to €1,800;
- removing and disposing of the old tank: €200 to €500.
Further down the same page, QuoteHub puts a 1,000 litre bunded tank, installed, at €1,500 to €2,500, with Dublin at the top of that range, and a 1,500 litre bunded tank at €2,000 to €3,000. Its two figures for the 1,000 litre bunded tank overlap but do not match, which is one more reason to get quotes for your own site.
Oil Tank Environmental Services, an installer, prices a standard replacement from €1,400. That covers draining the old tank, removing and disposing of it, and fitting a new tank on a sound existing base. If the base has failed, it adds €200 to €500 for a repair or a new one.
What the tank alone costs
Retail prices show how much of a quote is the tank itself. Irish retailer Tanks Direct listed these Carbery bunded tanks on 23 October 2026, including VAT, before delivery or fitting:
- Carbery Combi R bunded, 650 litres: €1,297.80
- Carbery rectangular bunded, 1,100 litres: €1,881.16
- Carbery vertical bunded, 1,350 litres: €1,793.40
- Carbery horizontal bunded, 1,350 litres: €2,156.55
- Carbery vertical bunded, 2,500 litres: €2,475.99
Some of the fitted ranges above are lower than these retail prices. Retail prices change with sales, and installers fit several brands. Ask each installer to name the make, model and capacity in the quote so you can check what you are paying for.
What a quote should list
Ask for each of these as a separate line, with VAT shown:
- the new tank, by make, model and capacity;
- pumping out any usable oil and storing it while the tanks are swapped;
- removing the old tank and disposing of it and the sludge in the bottom;
- checking the base, and the cost of repairing or replacing it if it is not sound;
- the fuel line, filter and fire valve. Technical Guidance Document J says an automatic fuel cut-off valve should be fitted;
- reconnecting the boiler and checking it fires.
Two quotes that look a few hundred euro apart often differ on removal or the base. Use an OFTEC-registered technician and get at least two quotes.
Does the new tank have to be bunded?
It depends on the size and the site. Under TGD J, a new or replacement tank needs secondary containment if it is inside a building, wholly below ground, holds more than 2,500 litres, or if a leak would be a significant risk of water pollution. That risk includes a tank within 10 metres of a river, stream, lake or the sea, within 50 metres of a well, borehole or spring, or where spilt oil could reach an open drain. Our guide to single-skin vs bunded oil tanks has the full list and the fire distances from the house and boundary.
On QuoteHub's figures, bunded adds about €400 to €600 to a 1,000 litre replacement. A leak costs far more. OFTEC says, from a UK perspective, that it is not unusual for a domestic oil spill to cost more than £20,000 to clean up, and that home insurance often limits cover for polluted ground. Ask your insurer whether the tank type affects your cover.
When does an oil tank need replacing?
OFTEC gives a tank an expected working life of around 20 years, though age alone does not decide it. Cracks, bulges, sun bleaching, rust, a sinking base or oil in the bund all need a technician's look. Our guide to an oil tank leaking covers the warning signs and what to do in the first hour.
If the tank is sound enough to choose the date, swap it when it is nearly empty so there is less oil to pump out and store. You can check your oil tank level with the gauge or a dipstick.
Is there a grant for a new oil tank?
We found no SEAI grant that pays for an oil tank. Our guide to heating oil grants in Ireland lists what is available to oil-heated homes, including help with heating controls and with replacing oil heating with a heat pump.
Common questions
How much does it cost to replace an oil tank in Ireland?
QuoteHub lists €800 to €1,200 to replace a 1,000 litre single-skin tank and €1,200 to €1,800 for a bunded one, and €1,500 to €2,500 for a fitted 1,000 litre bunded tank, with Dublin at the upper end. One installer prices a standard swap on a sound base from €1,400. Ask for written quotes that list the tank, removal, base and VAT separately.
How much does it cost to remove an old oil tank?
QuoteHub lists €200 to €500 to remove and dispose of an old tank. One installer charges from €380 to drain and remove a tank without replacing it, and more where access is awkward or a lot of oil is left inside.
How long does an oil tank last?
OFTEC gives a tank an expected working life of around 20 years. Cracks, bulges, rust, a sinking base or oil in the bund mean it needs a technician's opinion whatever its age.
Does my new oil tank have to be bunded?
Under Technical Guidance Document J, a new or replacement tank needs secondary containment, such as a bunded tank, if it is inside a building, wholly below ground, holds more than 2,500 litres, or a leak would be a significant risk of water pollution. That risk includes a tank within 10 metres of a river, stream, lake or the sea, or within 50 metres of a well, borehole or spring.
Next step
A new tank needs a first fill. Compare local oil suppliers to see delivered prices in your county, and book a boiler service if the fuel line was disturbed.
