Is There a Grant for a New Oil Boiler in Ireland? Honest Answer

The honest answer: no grant for a like-for-like oil boiler

If you're hoping the SEAI will help pay for a new oil boiler to replace your old one, here's the straight answer: no, there isn't a grant for that. The SEAI does not fund the purchase or installation of a replacement fossil-fuel boiler, oil or gas. So if your boiler is on its last legs and you're picturing a cheque towards a shiny new one, that particular grant doesn't exist.

That's the part people search for and rarely get told plainly. But it's not the whole story, because there is real money on the table for the house around the boiler.

What SEAI grants actually cover

Even though the boiler itself isn't grant-aided, several things that make an oil-heated home cheaper and warmer are. Under the SEAI Home Energy Grants scheme (via registered contractors), you can get support for:

• Heating controls: around €700. Zoning, timers and thermostats that stop you heating rooms you're not using. For many oil homes this is the single most relevant grant, and it cuts oil use immediately.
• Attic insulation and cavity wall insulation. Some of the best value per euro spent, and grant rates are meaningful.
• Internal or external wall insulation for solid-wall houses.
• Windows and doors as part of a deeper upgrade.

The idea is simple: a well-controlled, well-insulated house burns less oil per fill, whatever boiler is sitting in the shed.

The Warmer Homes Scheme (fully funded)

If you're on certain welfare payments (such as Fuel Allowance, Working Family Payment or others), the Warmer Homes Scheme can deliver insulation and energy upgrades free of charge. It's aimed at households at risk of energy poverty and is genuinely worth checking, because it can transform how much oil an older house needs. Eligibility rules apply, so confirm the current list before assuming.

Always check the live details on SEAI.ie and Citizens Information, as grant amounts and eligibility get updated.

Why the grants point away from oil (and what that means for you)

Most of the larger grants (heat pumps, one-stop-shop deep retrofits) are geared towards moving homes off fossil fuels. That's the policy direction, and it's why there's no oil-for-oil grant.

We're not here to push you towards a heat pump. A heat pump only performs well in a properly insulated, airtight home, and for many older Irish houses that means significant fabric work first. If your home isn't ready, a heat pump can leave you cold and disappointed. For plenty of households, the sensible path is: fix the insulation, add the heating controls, keep the oil boiler running efficiently, and reassess later. That's a legitimate choice, not a failure.

Getting real value while you keep your oil boiler

If a new boiler is coming out of your own pocket anyway, focus your energy (and any grants) where they pay back:

1. Claim the heating controls grant. Better zoning and timing is money back on every fill.
2. Sort the attic and walls. Insulation is the cheapest heat you'll ever "buy".
3. Service the boiler yearly with an OFTEC-registered technician so it burns clean and efficient.
4. Stop overpaying on the oil itself. This is where a lot of quiet savings hide.

That last point matters. The difference between suppliers on a single 900-litre fill can be tens of euro, and running dry (then paying for a boiler restart or an emergency top-up) wipes out any grant saving fast.

Simple next steps

• Check what you qualify for and read the plain-English breakdown on our grants guide.
• Confirm current amounts and eligibility on SEAI.ie and Citizens Information.
• While you're at it, compare local prices for your county so your next fill isn't more than it needs to be.
• Set up a price-drop alert so you hear when prices ease, without watching the market every day.
• Use our free tool to see when you'll run out and never get caught by a cold tank and a boiler lockout.

So: no grant for the boiler, yes to grants for the house around it, and plenty you can do today to spend less on oil either way.
