What Are SEAI Grants?
SEAI grants are non-repayable government payments that help Irish homeowners reduce the cost of making their homes more energy efficient. They are managed by the Sustainable Energy Authority of Ireland (SEAI) and funded by the Department of the Environment, Climate and Communications.
You do not pay SEAI grants back. They are not loans. Most are available to all homeowners regardless of income, and many can be combined — so you can claim multiple grants for the same property in the same year.
SEAI Grants 2026 — At a Glance
| Grant type | Maximum amount | Built before |
|---|---|---|

The Three Types of SEAI Scheme
1. Individual Energy Upgrade Grants (Better Energy Homes)
The most commonly used route. You choose one or more upgrades, apply to SEAI before work starts, hire an SEAI-registered contractor, complete the work, then claim your grant back. You manage the project yourself. Grants can be combined — for example, you can claim for attic insulation, solar panels and heating controls in a single application.
2. One Stop Shop Service (Deep Retrofit)
Ideal for whole-house retrofits. A single SEAI-registered provider manages everything — from your initial BER assessment to project completion and grant administration. Your home must reach at least a B2 BER rating after works are complete. The grant is deducted upfront so you only pay the balance. Maximum grant is €50,000.
3. Warmer Homes Scheme (Fully Funded)
For homeowners on qualifying welfare payments (Fuel Allowance, Disability Allowance, Working Family Payment and others). SEAI covers 100% of the cost — you pay nothing. Note: the waiting list is currently 24+ months. If you qualify but cannot wait, you can access enhanced individual grants in the meantime without losing your place.
What’s New in 2026?
- Heat pump grant doubled — rose from €6,500 to €12,500 (February 2026), now includes a €4,000 Renewable Heat Bonus and up to €2,000 for central heating upgrades.
- Windows & doors grant launched — a brand-new standalone grant introduced March 2026. Up to €4,000 for windows on a detached home, plus €800 per external door.
- Insulation grants increased — attic insulation for detached homes rose from €1,500 to €2,000. First-time buyers can now access €2,500.
- Second wall insulation allowed — from March 2026, homeowners who already claimed a cavity wall grant can apply for a second wall insulation measure.
- Enhanced welfare grants — homeowners on qualifying welfare payments can now access enhanced insulation grants rather than waiting 24 months for the Warmer Homes Scheme.
Am I Eligible?
General eligibility rules for most SEAI grants:
- You must own the property (owner-occupier or landlord)
- The property must be in Ireland
- For insulation and heating grants — property must have been built and occupied before 2011
- For solar and heat pump grants — built and occupied before 2021
- All work must be completed by an SEAI-registered contractor
- You must receive SEAI grant approval before work begins
Renters cannot apply directly. Landlords are eligible to apply for upgrades to rental properties.

Can I Combine Multiple Grants?
Yes. SEAI grants stack. Most homeowners who do a full upgrade combine several grants in a single project. A typical combination might include attic insulation + cavity wall insulation + heat pump + heating controls — each claiming its own separate grant. The One Stop Shop route allows you to combine all of these into a single managed project worth up to €50,000 in grants.
How Does the Application Process Work?
- Check eligibility — use our free grant checker above, or visit seai.ie
- Get quotes — from at least two SEAI-registered contractors
- Apply to SEAI before starting — you must have grant approval before work begins
- Complete the works — using your registered contractor
- Submit claim — with invoices, BER certificates and contractor details
- Receive payment — typically 4–8 weeks after submission
For One Stop Shop projects, your provider manages steps 2–6 on your behalf.
Frequently Asked Questions
Do I have to pay SEAI grants back?
No. SEAI home energy grants are non-repayable government payments. They are not loans and do not need to be paid back. They are also not subject to income tax.
Is there an income limit to qualify for SEAI grants?
No. The Individual Energy Upgrade Grants and One Stop Shop are available to all eligible homeowners regardless of income. Only the Warmer Homes Scheme (fully funded upgrades) has income or welfare payment requirements.
Can I apply for more than one SEAI grant at the same time?
Yes. SEAI grants can be combined. You can claim grants for multiple measures — for example, attic insulation, solar panels and a heat pump — in the same application or across multiple applications for the same property.
How long does SEAI grant approval take?
Individual upgrade grant approval is typically near-instantaneous for online applications. Grant payment after completed works usually takes 4–8 weeks. One Stop Shop and Warmer Homes applications take longer due to project complexity.
My home was built after 2011 — can I still get SEAI grants?
Partially. Insulation and heating grants require the property to have been built before 2011. However, if your home was built before 2021, you may still qualify for solar PV and heat pump grants. Homes built after 2021 generally do not qualify for SEAI home energy grants.
What is the maximum SEAI grant I can get in 2026?
For a full deep retrofit through the One Stop Shop route, the maximum grant is €50,000. For a vacant or derelict property, the refurbishment grant goes up to €70,000. Individual homeowners doing a combination of heat pump, insulation, solar and windows could combine €20,000+ in grants without going through the One Stop Shop.
