If you’ve been thinking about ditching the old oil or gas boiler, 2026 is honestly the best time to do it. Back on the 3rd of February, SEAI more than doubled its heat pump grant jumping from a maximum of €6,500 all the way up to €12,500. That’s a serious chunk of money, and it’s available to regular homeowners right now.
So Where Does the €12,500 Actually Come From?
It’s not one single lump sum it’s actually a bundle of three separate grants that stack together. You get up to €6,500 for the heat pump installation itself (air-to-water or ground-to-water systems), up to €2,000 for central heating upgrades like new radiators, pipework or underfloor heating if needed, and then a €4,000 Renewable Heat
That last one — the Renewable Heat Bonus — is the new piece of the puzzle. It’s specifically for homeowners switching away from fossil fuels, and it recognises a long-ignored reality: heat pumps are systems, not appliances, and many homes need more than just a box outside to make them work properly. So the grant now actually reflects the full cost of the transition, not just the unit itself.
Does Your Home Qualify?
Before you start getting quotes, there are a few boxes your home needs to tick.
The home needs to have an MPRN (your electricity meter number), and it must have been built and occupied before 2021. Most Irish homes will have no problem there.
The bigger question is insulation. Your home must meet a minimum Heat Loss Indicator (HLI) of 2.3 or below, meaning adequate insulation must be in place first. In other words, if your home is still losing heat like a sieve, you’ll need to sort the attic and walls before the heat pump grant kicks in.
The good news? If you already have a valid BER Certificate showing a compliant HLI of 2.3 or less, you can skip the Technical Assessment entirely and just upload a Self-Declaration form instead. Simple enough.
If your home was built from 2007 onwards, it’s even easier for homes built from 2007 onwards, there is no requirement to complete a Technical Assessment, though you may elect to do so.
What If Your Home Isn’t Heat Pump Ready Yet?
Don’t panic SEAI has thought of this too. Eligibility rules have been relaxed, and the minimum energy uplift requirement has been removed where a heat pump is installed under the One Stop Shop scheme.
And the insulation grants have also gone up this year, so you can sort your home out in stages. You can do insulation this year, windows next year, and a heat pump after that claiming separate grants as you go.
How to Actually Apply Step by Step
1. Check your BER Look up your home’s Building Energy Rating on the SEAI national register at seai.ie. If your HLI is already at or below 2.3, you’re in great shape and can move straight to the next step.
2. Get a Technical Assessment (if needed) If your home needs one, you’ll need to contract a registered SEAI technical advisor to conduct the assessment and a €200 grant is available to cover that cost, but only if you also apply for the heat pump system grant.
3. Get quotes from registered contractors This is important all work must be carried out by an SEAI-registered contractor, and you must have grant approval in place before you start any works. Don’t jump ahead and book the installation before your approval comes through, or you’ll lose the grant.
4. Apply online Head to seai.ie and apply through the Better Energy Homes portal. Select “Heat Pump System” on the measures page and the three grant components will be bundled automatically.
5. Get the work done, then claim Once the installation is complete, your contractor signs off, and you submit the required forms. Allow between 4 and 6 weeks for all grant payments to be processed and paid into your nominated bank account.
Can You Go Through a One Stop Shop Instead?
Absolutely, and for a lot of people this is the easier route. For homeowners who want simplicity, the One Stop Shop model remains central grants are deducted upfront and projects are fully managed by SEAI-registered providers. So rather than managing contractors yourself and claiming the money back, the One Stop Shop just takes the grant off your bill from the start. Less hassle, same money.
Already Had an Application In? Good News
The new maximum grant of €12,500 also applies to applications already in train with SEAI and not yet processed for payment. So if you applied before February and you’re still waiting, you should automatically get the higher amount. Worth double-checking with SEAI if you’re unsure.
The Bottom Line
The National Residential Retrofit Plan 2026 is backed by €558 million set aside specifically for home energy upgrades and retrofits. The government is clearly serious about this and the grant increase makes heat pumps a genuinely realistic option for a huge number of Irish homeowners this year.
If you’ve been putting it off, now is the time to at least check your BER and see where you stand. The process is more straightforward than it looks, and €12,500 off the cost makes a very compelling case for making the switch.
