Why Retrofit Your Irish Home?

Retrofitting your home with energy-efficient upgrades is one of the most impactful financial decisions you can make as a homeowner in Ireland. With SEAI grants covering up to €25,000 for deep retrofits, and research showing a B-rated home commands 10-15% more on the market, the return on investment is compelling.

SEAI Grant Scheme 2026

The Sustainable Energy Authority of Ireland (SEAI) offers a range of grants for home energy upgrades, including attic insulation, cavity wall insulation, heat pumps, solar thermal, and solar PV. Grants cover between 20% and 80% of costs depending on your household income and the type of upgrade.

Property Value Impact

Beyond the immediate energy savings, upgrading your BER rating adds tangible value to your property. A home with a B-rating or above is increasingly sought after by buyers who are conscious of energy costs and mortgage lenders offering green mortgage rates.

Frequently Asked Questions

What SEAI grants are available for home retrofitting in Ireland?

SEAI grants cover 20-80% of eligible upgrade costs depending on income and upgrade type. A full deep retrofit bringing a home to B2 BER can attract grants of up to €25,000. Solar PV panels attract up to €2,400.

Does a BER upgrade increase property value in Ireland?

Yes. Research suggests a B-rated home sells for 10-15% more than a comparable D or E-rated property in the same area. The effect is strongest in commuter towns and regional cities where energy bills are a major buyer concern.

What is the Warmer Homes Scheme in Ireland?

The Warmer Homes Scheme provides free energy upgrades to homeowners on qualifying social welfare payments, including insulation, heating controls, and a heat pump. It is fully funded by the Government with no cost to the homeowner.
