SEAI Heat Pump Grant Explained (2026)
SEAI heat pump grant values and eligibility in Ireland, including HLI requirements, application stages, assessment costs and the effect of the grant on total installation cost.
Typical grant: €4,500–€6,500 depending on property type
How the SEAI Heat Pump Grant Works
The SEAI Home Energy Grant scheme supports the replacement of fossil-fuel heating with qualifying heat-pump systems.
The source page lists a maximum grant of €6,500 for most houses and €4,500 for apartments.
Eligibility depends on the home’s thermal performance, the Heat Loss Indicator (HLI), use of an SEAI-registered contractor and completion of the required assessments.
Current Grant Values
Apartment: €4,500
Mid-terrace: €6,500
Semi-detached / end terrace: €6,500
Detached: €6,500
Eligibility & HLI
Eligibility Requirements
Property must meet the scheme’s age and occupancy rules.
An SEAI-registered contractor must carry out the installation.
A post-works BER assessment is required.
Heat Loss Indicator
The source page gives an eligibility threshold of HLI ≤ 2.0 W/K per m².
Homes above the threshold may need attic, wall, window or other insulation upgrades before the heat pump grant can be approved.
Grant Impact & Assessment Costs
| Item | Typical Cost / Value |
|---|---|
| Pre-install BER assessment | €150–€300 |
| Technical heat-loss assessment | €200–€500 |
| Additional insulation upgrades | €1,500–€8,000 |
| Typical heat-pump installation | €12,000–€24,000 |
For a semi-detached example at €17,500, the €6,500 grant reduces the net homeowner cost to €11,000. The source estimates that the grant commonly offsets about 25%–40% of installation cost.
Application & Payment Sequence
The normal sequence is: energy assessment, grant application, approval, installation, post-works BER and grant payment.
Approval should be received before installation begins.
The source page gives 1–3 weeks for grant approval, 1–2 weeks for the post-works BER and 4–8 weeks for payment processing.
Common Reasons for Grant Rejection
| Issue | Why It Matters |
|---|---|
| HLI above the threshold | Home may require fabric upgrades first |
| Installation before approval | Can invalidate grant eligibility |
| Installer not SEAI registered | Does not satisfy scheme rules |
| Incomplete documentation | Can delay or prevent payment |
Separate insulation measures may qualify for other SEAI supports, so a home that needs pre-install upgrades can sometimes combine grants.
Cost, VAT & Retrofit Interaction
Typical Net Cost
Installation before grant: €12,000–€24,000
Typical net homeowner cost after grant: €8,500–€18,000
Required upgrades can push the overall retrofit budget higher.
VAT Treatment
The source page states that residential heat-pump installation is typically charged at 13.5% VAT.
The grant is deducted from the project cost including VAT.
Other Retrofit Measures
Attic, cavity-wall, external-wall and solar PV grants may also be relevant.
Combining measures can improve both eligibility and long-term system performance.
Summary
The source-page grant range is €4,500–€6,500 depending on property type.
The key technical hurdle is HLI ≤ 2.0 W/K per m².
Homeowners should budget for assessments and any required insulation upgrades, and should not begin the heat-pump installation before grant approval.
