Energy costs continue to shape how Irish homeowners think about their homes. In 2026, SEAI grants remain one of the most powerful tools available to help households improve comfort, cut bills, and futureproof their properties.
But with changing rules, eligibility criteria, and grant amounts, many homeowners are unsure what they can actually claim this year. This guide breaks it down clearly, simply, and honestly.
What Are SEAI Home Energy Grants?
SEAI grants are government-backed supports designed to help homeowners improve the energy efficiency of their homes. The goal is simple: reduce energy waste, lower carbon emissions, and make homes warmer and healthier to live in.
In 2026, grants continue to support both single upgrades and full-home retrofits, depending on your goals and your home’s current energy performance.
Who Can Apply in 2026?
You may be eligible for SEAI grants if:
- Your home was built and occupied before 2011
- The property is used as a private residence
- The works are carried out by SEAI-approved contractors
Both older homes and newer builds can qualify, provided they meet the scheme criteria. A professional home energy consultation confirms eligibility before any work begins.
Common Energy Upgrades Supported by SEAI
Depending on your home, you may be able to receive grant support for:
- Attic insulation
- Cavity wall insulation
- External or internal wall insulation
- Air to water heat pumps
- Heating controls
- Solar PV panels
- Windows and doors, when included as part of a full retrofit
Each measure plays a different role in improving comfort, efficiency, and BER rating.
How Much Can You Claim?
Grant values vary depending on both the type of upgrade and your property type. In 2026, SEAI grants continue to cover a substantial portion of overall retrofit costs, particularly when multiple measures are combined under a structured plan.
To give you a clearer picture of what is currently available, below is a breakdown of the updated 2026 grant amounts and eligible measures.
Why Acting Now Matters
Energy upgrades are not just about saving money today. Homes with better energy ratings are:
- Cheaper to heat
- More comfortable year-round
- Less affected by future energy price rises
- More attractive to buyers
SEAI funding levels can change, and demand continues to rise. Acting sooner gives you better access to funding and contractor availability.
