Insulation grants in Ireland
SEAI insulation grants can help with attic and wall insulation, but amounts and eligibility depend on dwelling type and insulation method.
Plain-English summary
SEAI insulation grants can support attic insulation, cavity wall insulation, internal dry lining and external wall insulation. The right grant depends on the building and the surface being insulated.

Which guide should you read?
Enhanced attic support can apply to qualifying first-time buyers, welfare recipients and eligible active HAP/RAS properties. Enhanced cavity support covers qualifying welfare and eligible HAP/RAS routes. The individual guides explain dwelling-type amounts and checks; neither benefit receipt nor tenancy support guarantees approval. A second wall measure may qualify under SEAI’s progression rules, without duplicate funding for the same work.
