Get ListedProper home insulation is the single most effective way to reduce energy bills, eliminate dampness, and improve your property’s Building Energy Rating (BER). With heating costs rising, upgrading your attic, cavity wall, or external wall insulation keeps heat inside during winter and lowers carbon emissions. In Ireland, the Sustainable Energy Authority of Ireland (SEAI) offers substantial cash grants and even fully funded insulation retrofits for lower-income households. Constructors.ie lists background-checked, SEAI-registered insulation contractors.
External Wall Insulation (EWI), also known as wrap insulation, involves fixing high-density insulation boards to the exterior walls, finished with a weather-resistant render. Highly effective for solid block or stone walls.
Cavity wall insulation involves pumping insulating beads or foam through small holes drilled in the exterior walls. Internal wall drylining, attic mineral wool rolls, and underfloor insulation are other common options.
Irish homeowners can access fixed grants under the SEAI Individual Energy Upgrade scheme. Attic insulation grants range from 1,200 to 1,500 euro (covering up to 80% of costs). Cavity wall insulation grants are fixed at 1,200 euro.
External wall insulation (EWI) grants provide 6,000 euro, while drylining (internal) insulation offers 1,500 euro. Homeowners receiving fuel allowances may qualify for 100% free retrofits under the Warmer Homes Scheme.
An attic insulation upgrade for a standard semi-detached home costs €1,400 to €2,000 (net cost after the €1,200 grant is €200 to €800). Cavity wall insulation costs €1,600 to €2,400 (net cost after the €1,200 grant is €400 to €1,200).
External wall insulation (EWI) ranges from €14,000 to €22,000 (net cost after the €6,000 grant is €8,000 to €16,000).
Homeowners can claim up to €1,500 for attic insulation, €1,200 for cavity walls, and €8,000 for external wall insulation depending on the house type.
For a standard semi-detached home, EWI costs €14,000 to €18,000 before the €6,000 SEAI rebate is deducted.
Generally no, unless the external render significantly alters the character of a protected structure or faces a public road in a Conservation Area.
Yes, if you qualify for the SEAI Better Energy Warmer Homes Scheme (fuel allowance, jobseekers allowance with children under 7, etc.), the work is completed 100% free.
Attic and cavity bead pumping are completed in 1 to 2 days. External wall insulation takes 7 to 12 working days due to plaster drying requirements.
Attic insulation offers the fastest return on investment. For older solid block homes, external wall insulation (EWI) yields the best thermal improvements.
