SEAI insulation and heating grants in 2026

SEAI grants are fixed amounts that depend on your house type and the upgrade you choose. You can combine several grants, for example external wall insulation, attic insulation and heating controls, as long as each one is done by an SEAI-registered contractor.

SEAI individual grant rates for 2026. External doors are funded at €800 per door, up to two doors. Heat pump grants were increased in February 2026; we confirm the current amount for your home during the survey. Always check seai.ie for the latest figures.

Who can apply?

  • Homeowners and landlords of homes in the Republic of Ireland.
  • For wall and attic insulation, the home must have been built and occupied before 2011.
  • The home must not have received an SEAI grant for the same upgrade before.
  • From 2 March 2026, homes that already had a cavity or internal wall insulation grant can apply for a second wall measure, in line with SEAI’s rules. Homes that received an external wall insulation grant cannot get another wall grant.

How the grant process works

  1. Free survey and quote: we visit your home, recommend the upgrades that make the biggest difference, and confirm which grants apply.
  2. Apply to SEAI: you apply online and receive a grant offer. Work must not start before the offer is approved.
  3. Installation: our team carries out the work to SEAI standards.
  4. Post-works BER: an independent BER assessor rates your home after the work. SEAI contributes €50 towards this.
  5. Grant payment: you submit the declaration of works and BER, and SEAI pays the grant once the paperwork is approved.
