SEAI External Wall Insulation Grant 2026 (The Wrap Grant)

SEAI Grant Amounts by Property Type: Apartment, Mid-Terrace, Semi-D, Detached

Under the SEAI Better Energy Homes scheme (frequently referred to on Citizens Information as "external wall insulation – the wrap"), grant amounts are fixed cash allowances determined by the dwelling type:

• Detached House (€8,000 SEAI Grant): The highest individual insulation grant available (SEAI grant €8000 insulation) for standalone homes with 4 exposed external walls.
• Semi-Detached / End-of-Terrace (€6,000 SEAI Grant): Applies to three exposed external walls (front, gable/side, and rear).
• Mid-Terrace House (€3,500 SEAI Grant): Covers the front and rear external facade walls of terraced dwellings.
• Apartment (€3,000 SEAI Grant): Applies to external walls of ground, mid-floor, or top-floor apartments.

Second Wall Measure from 2 March 2026 (Had Cavity, Now Want the Wrap)

Historically, homeowners who previously claimed a grant for pumped cavity wall insulation or internal drylining were locked out of claiming an external insulation grant. Under the SEAI Second Wall Measure effective from 2 March 2026, if your home has hollow block walls, solid block sections, or uninsulated extensions, you can now claim the full SEAI wrap grant to complete a comprehensive thermal wrap.

Property Eligibility: Built Before 2011 (Occupied on or Before 31 Dec 2010)

To qualify for any external insulation grant Ireland scheme in 2026:

• The property must have been built and occupied on or before 31 December 2010 (verified via MPRN and ESB electricity meter connection date).
• You must receive official SEAI pre-approval before any work commences on site.
• The entire external wall surface must be insulated using an NSAI-certified system (such as Baumit openSystem or Baumit EPS) to achieve a U-value of 0.21 W/m²K or better.
• A post-works BER assessment by an independent assessor is required upon completion to finalize the SEAI grant file.
