Support to upgrade homes in Ireland

How SEAI grants help with home energy upgrades

SEAI grants help homeowners in the Republic of Ireland upgrade insulation, heating and renewable energy systems. They reduce the cost of making homes warmer, more efficient and cheaper to run.

On this page we summarise the main SEAI grant routes and grant amounts for key measures such as attic and wall insulation, heating controls, heat pumps and solar PV.

Premier Insulations is an SEAI-registered contractor for homes in the Republic of Ireland. We can help you match the right upgrades with the right grants and plan a practical upgrade path.

Main SEAI grant routes for homes

Most homeowners use one of these SEAI routes:

  • Individual Home Energy Grants — step-by-step grants for specific measures such as attic and wall insulation, heating controls, heat pumps and solar PV.
  • National Home Energy Upgrade Scheme  — deeper retrofit projects managed by SEAI-registered providers, aiming for at least a B2 BER.
  • Warmer Homes Scheme — fully funded energy upgrades for certain eligible homeowners on specific welfare payments and living in older homes.

The best route for you depends on your budget, current BER and how far you want to go with your upgrade.

  • Lower upgrade costs

    Grants reduce what you pay for insulation, heating and renewable upgrades in your home.

  • Flexible routes

    Use grants step by step or as part of a deeper energy upgrade, depending on your goals and budget.

  • Trusted national scheme

    Clear rules, registered contractors and quality checks under SEAI’s national grant programmes.

What customers say

“After we used SEAI grants for attic and cavity wall insulation, the house holds the heat much better. The heating is on for fewer hours and the rooms are far more comfortable.”

– Homeowner, Co. Kildare

“We weren’t ready for a full retrofit, but SEAI grants made it affordable to start with insulation and heating controls. Premier Insulations explained the options and helped us plan the upgrades in stages.”

Other SEAI-supported measures

In addition to insulation, heating controls, heat pumps and solar, SEAI can also provide grants for other measures as part of individual or deeper upgrade projects, including:

  • Floor insulation (up to €3,500 for houses).
  • Windows (complete upgrade) — grant up to €4,000 for a detached house, with lower amounts for other dwelling types.
  • External doors — €800 per door (maximum two doors).
  • Mechanical ventilation — support for certain ventilation systems in deeper retrofit projects.
  • Airtightness works — grant support when part of a specified upgrade package.
  • Home Energy Assessment & BER and project management in One Stop Shop projects.

Not every measure is appropriate for every home. We will always advise which of these make sense for your property and upgrade plan.

Who SEAI grants are for

SEAI home energy grants are primarily for:

  • Homeowners and non-corporate landlords in the Republic of Ireland.
  • Homes built and occupied before a cut-off year (for example, before 2011 for many insulation and heating control grants, and before 2021 for heat pump and solar PV grants).

Each scheme (individual grants, One Stop Shop, Warmer Homes) has its own detailed eligibility rules on construction year, previous grants and minimum energy performance. These can change over time, so always check the latest criteria on the SEAI website.

SEAI grants – quick answers

What are the main SEAI grants for homes?

The main supports are individual Home Energy Grants for measures such as attic and wall insulation, heating controls, heat pumps and solar PV,
the National Home Energy Upgrade Scheme (One Stop Shop) for deeper retrofits to at least a B2 BER,
and the Warmer Homes Scheme for certain eligible homeowners.

Are grant amounts the same for all house types?

No. Many SEAI grant amounts vary by dwelling type. Detached houses usually receive higher amounts, with lower values for semis, terraces and apartments.
Solar PV grants are based on system size (kWp) rather than house type. The values on this page are indicative; exact figures are listed in SEAI’s grant tables.

Do SEAI grant amounts change?

Yes. SEAI can update grant amounts and eligibility rules over time.
Solar PV grants, for example, have changed in recent years.
Always check the latest information on the SEAI website before applying.

Do I have to use an SEAI-registered contractor?

Yes. For individual Home Energy Grants you must use an SEAI-registered contractor.
Premier Insulations is an SEAI-registered contractor for homes in the Republic of Ireland.

How do I know which SEAI route is best for my home?

The best route depends on your budget, current BER, the age and condition of your home, and whether you might qualify for fully funded supports.
A home survey and, where appropriate, a Home Energy Assessment & BER
will make the options much clearer.
