Ireland’s enhanced insulation support for eligible HAP and RAS rental homes has two separate tests: the tenancy arrangement and the building. Passing one does not establish the other. SEAI’s current application guidance dates the higher support for attic and cavity wall insulation from 6 October 2026; the package was announced on 29 September. [1][4]

That distinction gives tenants and landlords a useful starting point for a winter upgrade conversation. This guide explains the published route and helps prepare questions; it does not determine whether a particular property qualifies.

Check the tenancy and the property separately

SEAI says the property must have an active Housing Assistance Payment tenancy or Rental Accommodation Scheme arrangement, and must have been built and occupied on or before 31 December 2010. Evidence of the active arrangement may be requested. [1][2]

For attic insulation, previous funding for that measure at the same MPRN excludes a home. Apartments need particular attention: SEAI limits the attic grant to top-floor apartments or those losing heat through the roof to the outside; an apartment with separate apartments directly above is excluded. [2]

Keep four questions on one record: which arrangement is active; when was the home built and occupied; has this insulation measure received funding before; and which registered contractor can assess the proposed work? A missing answer is something to establish before relying on a grant figure.

Read a grant amount as a contribution

SEAI’s enhanced attic-insulation figures are €2,500 for a detached house, €1,900 for a semi-detached or end-of-terrace house, €1,800 for a mid-terrace home and €1,400 for an eligible apartment. They depend on eligibility and property type. [2]

These are grant amounts, not a promise that the entire quotation will be covered. Compare the written price, the applicable grant and the remaining cost as separate entries. Ask the contractor to identify what the quotation includes rather than using a headline maximum as a budget.

Put approval before installation

The landlord guidance identifies the landlord as the homeowner applying for individual grants. SEAI requires a registered contractor for the work and says the grant offer must be accepted before works begin. [1][3]

A tenant can use these official links to ask the landlord whether the route is relevant and how an assessment or visit would be arranged. The practical preparation is finding records and agreeing questions; suitability assessment and insulation installation belong with the appropriate professional.

Finally, keep the insulation route separate from solar support. SEAI describes a distinct solar-and-battery pilot connected to the existing Dublin RAS pilot, rather than a general offer to every HAP or RAS home. [3]

The linked guidance was checked on 10 October 2026. Confirm the current scheme terms and the property’s eligibility with SEAI before commissioning work.
