SEAI Grant Amounts 2026: Every Home Energy Grant in Ireland
Complete list of SEAI home energy grant amounts for 2026 — solar panels (€1,800), heat pumps (€12,500), insulation (€8,000), windows (€4,000), and more. Eligibility rules, amounts by property type, and how to apply.
The Irish government offers over €37,000 in home energy upgrade grants through the Sustainable Energy Authority of Ireland (SEAI). Whether you're looking at solar panels, a heat pump, insulation, new windows, or heating controls — there's a grant to help cover the cost.
We built our SEAI Grant Checker using the official Home Energy Upgrades grant schedule (PDF) published by the Department of Housing, Local Government and Heritage — the same document SEAI uses to determine grant amounts.

Every SEAI Home Energy Grant Explained
Below is the full breakdown of every grant available under the Better Energy Homes scheme, the Solar PV Scheme, and the National Home Energy Upgrade Scheme (One Stop Shop).
Solar PV Grant
Solar PV Scheme
The SEAI Solar PV grant helps cover the cost of installing solar electricity panels on your home. The grant is calculated per kilowatt-peak (kWp):
- •€700 per kWp for the first 2 kWp
- •€200 per kWp for the next 2 kWp (2–4 kWp)
- •Maximum grant: €1,800 (for a 4 kWp system or larger)
A typical 10-panel system (~4.2 kWp) costs €7,000–€9,000 before the grant. After the €1,800 grant and 0% VAT on residential solar, most homeowners pay €5,500–€7,500 out of pocket. Payback is typically 5–8 years. Your home must have been built and occupied before 2021.

Solar Thermal Grant
Better Energy Homes
Solar thermal panels heat water directly using the sun, reducing hot water costs by up to 60%. The grant is a flat €1,200 regardless of property type. Typical cost is around €4,500 installed.
Solar thermal is different to solar PV — it heats water rather than generating electricity. You can claim both grants on the same property.
Heat Pump Grant
Better Energy Homes
The largest individual energy upgrade grant in Ireland. The heat pump bundle has three components:
- •Heat pump unit: up to €6,500
- •Distribution upgrades (radiators, underfloor heating): up to €2,000
- •Renewable heat bonus for replacing fossil fuel/electric heating: up to €4,000
Not everyone qualifies for all three — actual grant depends on your system and what upgrades are needed. Apartments receive up to €9,500 (unit €4,500 + distribution €1,000 + bonus €4,000).
Typical cost: €15,000–€20,000. Not available if you already have a heat pump.
Air-to-Air Heat Pump Grant
Better Energy Homes
Air-to-air heat pumps provide both heating and cooling. Grant is up to €7,500 for houses, €3,500 for apartments. Eligible for homes replacing fossil fuel or electric storage heating.
You can only claim one heat pump grant — standard or air-to-air, not both.

Who Qualifies for SEAI Home Energy Grants?
The eligibility criteria for SEAI individual home energy grants are straightforward:
- Owner-occupier — you must own and live in the property
- Home built before 2021 — properties built to NZEB (Nearly Zero Energy Building) standards from 2021 onwards are not eligible, as they already meet high energy performance requirements
- Connected to the electricity grid
- Each grant claimed once per property — with the exception of wall insulation grants, which can now be claimed a second time (as of Spring 2026)
- Work must not start before SEAI approval — this is the most common reason applications are rejected
Homes Built After 2010
If your home was built between 2011 and 2020, you're only eligible for heat pump, solar PV, and solar thermal grants. Insulation grants are not available because homes built in this period already meet reasonably modern building regulations for energy efficiency.
Enhanced Grants for Social Welfare Recipients
If you receive certain social welfare payments, you may qualify for higher grant amounts on some measures (attic insulation, cavity wall insulation, and BER assessments). Qualifying payments include:
- Fuel Allowance
- Disability Allowance
- Domiciliary Care Allowance
- Blind Pension
- Invalidity Pension
- Jobseeker's Allowance (long-term)
- One-Parent Family Payment
- Widow/Widower's Pension
- Working Family Payment
- Carer's Allowance
First-Time Buyer Enhanced Grants
First-time buyers qualify for enhanced attic insulation grants — the same higher amounts as social welfare recipients. This is designed to help new homeowners improve older properties they've just purchased.
The Warmer Homes Scheme — Free Energy Upgrades
100% free upgrades for qualifying households
If you receive a qualifying social welfare payment (Fuel Allowance, Disability Allowance, Jobseeker's Allowance, One-Parent Family Payment, Carer's Allowance, etc.), you may be eligible for fully funded insulation, heating, and solar panels at no cost.
Managed directly by SEAI. Typically a waiting list of several months, but the upgrades are comprehensive — covering works that could cost €20,000+ privately.
One Stop Shop Grants (National Home Energy Upgrade Scheme)
The National Home Energy Upgrade Scheme (One Stop Shop) offers additional grants not available through the standard route. Accessed through SEAI-registered providers who manage the entire retrofit:
The One Stop Shop route suits deep retrofits — the goal is typically to bring your home to a B2 BER rating or better, which can significantly increase property value.
How to Apply for SEAI Grants
The application process is the same for all individual Better Energy Homes grants:
- 1
Get quotes from SEAI-registered contractors. We recommend at least 3 quotes.
- 2
Apply to SEAI through their online portal. You'll need your property details and contractor's SEAI registration number.
- 3
Wait for written approval — typically 2–4 weeks. Do not start work before approval.
- 4
Have the work completed by your SEAI-registered contractor within 8 months of approval.
- 5
Submit your Declaration of Works and proof of payment to SEAI.
- 6
Receive your grant — paid directly into your bank account, typically within 4–6 weeks.
Common Mistakes That Get Applications Rejected
- ✗Starting work before approval — the most common rejection reason. You must wait for SEAI's official letter.
- ✗Using a non-registered contractor — they must be on SEAI's list for that specific grant type.
- ✗Incomplete documentation — ensure your Declaration of Works is complete with all receipts.
- ✗Claiming a grant twice — each grant once per property (except wall insulation, which now allows a second claim).
How Much Could You Save in Total?
If you claimed every available grant for a detached house, the total comes to over €37,000 in government grants for home energy upgrades. Even for a semi-detached home, the total exceeds €30,000. In practice, most homeowners claim 2–4 grants.
