External Wall Insulation Cost in Dublin & Ireland

External wall insulation in Ireland typically costs €100-€110 per m² installed, including insulation board, mesh, render and scaffolding. Total project cost ranges from €8,500 for an apartment to €26,000 for a large detached home, before the SEAI grant is deducted.

A standard three-bed semi-detached Dublin home costs roughly €18,000 to externally insulate before grants. After the typical €6,000 SEAI grant for semi-detached properties, the net cost is usually around €12,000.

Budget €95-€110 per m² depending on house type — larger detached homes benefit from a lower per-m² rate due to economies of scale on scaffolding and setup, while smaller apartments and mid-terrace homes sit at the higher end of the range.

"Wrapping" a house — insulating and rendering the full external envelope — costs €8,500-€26,000 in Ireland depending on size and house type. Coastal properties often need a silicone render finish for weatherproofing, which can add 5-10% to the total.

Yes for most pre-2011 Irish homes. Wall U-values typically fall from around 2.0 W/m²K to 0.27 W/m²K, cutting heating bills by 25-45% and lifting the BER rating by two to three bands. Combined with the SEAI grant, simple payback is usually 7-10 years, and the improved BER directly raises resale value.

The prices above are shown both before and after the grant. SEAI grants of €3,500-€8,000 are deducted from your final invoice once the post-works BER assessment is complete — you only pay the net amount, and we handle the paperwork.

The main factors are total wall area, house type (detached homes have more wall area but a lower per-m² rate), render finish (silicone costs more than silicone-acrylic but performs better on coastal properties), scaffolding access, and the condition of the existing wall surface.
