SEAI administers the main national grant schemes for home energy upgrades in Ireland, covering measures such as attic and wall insulation, heat pumps, solar PV panels, and fully-managed deep retrofit ('one-stop-shop') projects, with grant amounts varying by measure and dwelling type. Some local authorities and other bodies also run targeted schemes, particularly for older or vulnerable homeowners, so it's worth checking current SEAI and local authority listings for exact eligibility and amounts.
The Sustainable Energy Authority of Ireland (SEAI) runs the primary suite of national grant schemes supporting homeowners who want to improve their home's energy efficiency. These generally fall into a few categories: individual grants for specific measures such as attic insulation, cavity wall insulation, external wall insulation, heat pumps and solar PV panels; and the fully-managed 'one-stop-shop' or National Home Energy Upgrade Scheme, where an approved contractor manages a whole-house deep retrofit project, often aiming for a BER of B2 or better, with grant support covering a significant portion of the cost.
Eligibility, grant amounts and required combinations of measures vary depending on the scheme, the age and type of the dwelling, and whether the homeowner is applying individually or through a registered one-stop-shop provider. Some grants require works to be carried out by a registered contractor and may require a pre- and post-works BER assessment to confirm the improvement achieved. Because grant values and scheme rules are periodically updated, current figures should always be checked directly on SEAI's website before committing to works.
Separately, some local authorities and other state bodies operate targeted supports, such as retrofit schemes for social housing, energy poverty schemes for low-income or vulnerable households, and area-based retrofit programmes, which may have different eligibility criteria to the general SEAI grants aimed at homeowners.
