Is There a Grant to Replace an Oil Boiler in Ireland? Not for the Boiler

There is no SEAI grant to replace an oil or gas boiler with another oil or gas boiler. SEAI puts it in one line: “We do not give grants for new or replacement fossil fuel boilers, such as gas or oil.” But that same line goes on to say something most people never get told, and it's worth €700 to you. (seai.ie, section 2.2)

Why the Top Results Quote a €700 “Boiler Grant”

Search oil boiler replacement grant Ireland and the results contradict each other inside the first half-page. We checked every one of them on 21 August 2026.

SEAI's own page ranks first, saying it does not fund boilers. Two installer pages rank second and fifth, both offering a €700 SEAI grant for an oil boiler replacement. Both sets of figures trace back to something real, which is exactly why this is so hard to sort out from the outside.

A Dublin plumbing firm's page, sitting at number two, states: “The SEAI Grant for the heating controls is €600 and the grant for Oil boiler or Gas boiler with the heating controls upgrade is €700.” Further down it adds that householders “can get a grant of €700 Euro towards the cost of a new high efficient oil boiler or gas boiler replacement”. Neither figure matches SEAI's 2026 list. The controls grant is €700, not €600, and nothing is payable towards the boiler. That page describes an older version of Better Energy Homes: it dates its own figures to a scheme launched in May 2011 and last uprated in March 2015, and its images were uploaded in 2015.

The number-five result, from an SEAI-registered One Stop Shop, is a different case. Its oil boiler replacement page carries the heading “€700 SEAI Grant Available” and lists “Expert oil boiler replacement” and “Up to €700 SEAI grant” in the same breath. That €700 is a live, correct figure, and their installation bundle does include heating controls. It is the heating controls grant, and it is genuinely claimable on a job where a new boiler goes in. Presented beside the words oil boiler replacement, though, it reads as a grant towards the boiler, and it isn't.

So if a quote lands in your inbox with “€700 SEAI grant” beside a new oil boiler, the money is real and the installer may well be registered. Ask one question before you sign: is that €700 for the controls? If the answer is anything other than yes, the figure isn't on SEAI's 2026 list, whatever the page you read it on says.

Why There's No Boiler Grant

The reasoning isn't hidden. SEAI's Warmer Homes Scheme is the fully-funded scheme for people on qualifying welfare payments, the most generous support the state offers. Its own page says it plainly: “we do not support the installation of oil or gas boilers”. And on why: “Under European legislation the scheme can no longer fund oil or gas boilers.” (seai.ie)

Grant money is meant to cut a home's emissions permanently. A new condensing boiler burns less fuel than a twenty-year-old one, but it still locks in another fifteen years of burning fuel. A heat pump doesn't. That's the whole argument, and it's why every euro that once went to boilers now sits behind the heat pump.

Boiler upgrades did attract grant support in Ireland years ago, under earlier schemes. They don't now, and nothing on SEAI's current list suggests they're coming back.

What You Can Actually Get in 2026

Here is SEAI's full individual-grant list as it stands today. Read down it and you'll notice what's missing.

Eight grants, and not one of them puts a boiler on your wall. If you're here because of a boiler, two of them are worth understanding properly.

The €700 Heating Controls Grant: The Closest Thing to a Boiler Grant

If your boiler is fine and you just want the heating to cost less, this is the grant that applies to you. It doesn't touch the boiler itself. It pays for the controls around it: a timer, a room thermostat, a cylinder thermostat, thermostatic radiator valves. The point is to heat the rooms you're actually using, when you're using them, and to heat water without heating the whole house.

• €700, flat, regardless of property type.
• Claimable “with or without installing a high efficiency boiler”, in SEAI's own words. If you're replacing the boiler anyway, the controls grant does not disappear.
• Your home must have been built and occupied before 2011, and have an MPRN. It's on your electricity bill.
• You cannot claim it if you're applying for, or have previously claimed, the heat pump system grant.
• You must use an SEAI-registered contractor, and have grant approval before any work starts. Start first and you forfeit it, and a dead boiler is exactly when people start first.

That last point is where this grant is actually lost. The rule is not that a new boiler blocks the €700. The rule is that beginning work before your grant offer is accepted blocks it, and an emergency boiler replacement is the single most likely job to begin before anyone applies for anything.

The heat pump exclusion matters too. Controls and a heat pump are an either/or. If a heat pump is realistic for your home in the next few years, don't spend the €700 allowance now.

The €4,000 Bonus for Taking the Boiler Out

This is the part most people searching for a boiler grant never find, and it's the one worth real money. SEAI's heat pump grant rose sharply on 3 February 2026, from a maximum of €6,500 to a maximum of €12,500. It's now a bundle of three grants rather than a single payment:

• Up to €6,500 for the heat pump unit itself.
• Up to €2,000 for central heating work where it's needed, meaning new radiators or underfloor heating.
• €4,000 Renewable Heat Bonus for homeowners swapping out an existing oil or gas boiler, solid fuel system or electric storage heating.

Read that third one again. There is no grant to replace your boiler, but there's €4,000 on the table to remove it. That's the policy in one line.

The total depends on your dwelling type and on what your installer's design actually requires. The unit grant is the part everyone gets, while the central heating and bonus grants depend on your circumstances. Air-to-air systems, which don't heat hot water, are grant-aided to a lower maximum. Homes built before 2007 need a technical assessment first unless they already hold a valid BER showing a low enough heat loss indicator, and there's a €200 grant towards it. Our heat pump grant guide has the full breakdown by system and dwelling type.

“My Boiler Has Died and I Need Heat Now”

Then this page has bad news, and you deserve it straight rather than after four more searches. There is no grant, emergency or otherwise, to get a new boiler fitted. Warmer Homes doesn't fill the gap either. SEAI's own scheme FAQ answers the question directly: it “only supports renewable heating systems (like heat pumps). It does not replace oil or gas systems.” Read that as the answer to the question it's filed under, which is “my heating is broken, can I get a replacement?”. The scheme may take an oil system out and put a heat pump in where the home suits one. What it will never do is put another oil or gas system back. And even for the measures it does cover, works are currently taking up to 24 months from application, so it was never going to heat your house this winter.

So if the boiler is gone and the house is cold, you're paying for that yourself. What the grants can do is change what you spend afterwards. If you're about to spend thousands on heating anyway, that's exactly the moment to price a heat pump against a boiler. The €12,500 changes the comparison, and it's the only moment the €4,000 bonus is ever available to you.

One thing you can do while a Warmer Homes application sits in the queue: since 2026, homeowners on qualifying welfare payments can claim higher individual insulation grants without losing their place. That's up to €2,500 for attic insulation and up to €2,300 for wall insulation, applied for separately with your own SEAI-registered contractor. You pay upfront and are refunded. It won't heat the house tonight, but it's the one route that doesn't involve waiting two years.

Is There a Boiler Grant for Over-70s or Pensioners?

No, and the framing is the problem rather than the answer. Age is not a criterion for any SEAI grant. There is no over-70s scheme, no pensioner rate, and no age band on the boiler question, because there is no boiler grant to qualify for at any age.

What people usually mean by this is Warmer Homes, the fully-funded scheme. It has four criteria, and none of them is your age:

• You own and live in the home as your main residence.
• The home was built and occupied before 2006.
• You receive one of seven qualifying welfare payments: Fuel Allowance, Working Family Payment, One-Parent Family Payment, Domiciliary Care Allowance, Carer's Allowance (living with the person you care for), or Jobseeker's or Disability Allowance for over six months with a child under seven.
• A survey finds the home suitable for improvements. Some homes are found unsuitable and get nothing.

The reason the over-70s association exists at all is Fuel Allowance, which many older households receive and which is the most common route onto the scheme. So it is means-tested, through the welfare payment, and not age-tested. And it still will not fit you a boiler: SEAI's own scheme FAQ says it “only supports renewable heating systems (like heat pumps)”.

Is There a Grant to Switch from Oil to Gas?

No. Swapping an oil boiler for a gas boiler is a fossil-fuel-to-fossil-fuel change, and SEAI's line covers both by name. You'd also be paying for a gas connection on top of the boiler, for a system the grant list is designed to move homes away from.

The €700 controls grant is still available on that job, on the same terms as any other boiler swap. The €4,000 Renewable Heat Bonus is not, because it is only paid when the replacement is a heat pump. Oil to gas is the one switch where you spend the most and the grant system offers you the least.

Where Solar Fits

Solar panels won't heat your home, and this site isn't going to pretend otherwise. What they do is cut the electricity bill. That gets a lot more interesting the moment your heating runs on electricity instead of oil.

Swap a boiler for a heat pump and your heating moves onto your electricity bill. Solar then offsets part of it, and the two grants stack. The €1,800 Solar Electricity Grant and the heat pump grant are separate schemes with separate applications, and claiming one doesn't affect the other. Solar also carries 0% VAT on a supply-and-install job, and surplus generation earns you money through the Clean Export Guarantee. We've worked the combined numbers on the heat pump and solar grant stack.

If hot water rather than heating is what you're really trying to solve, the €1,200 solar water heating grant is a different product with a different sum behind it. It's the one grant on the list that competes with your boiler for the job it currently does in summer.
