External Wall Insulation Cost Breakdown for Irish Homes

Why External Wall Insulation Costs Are Not One-Size-Fits-All

One of the most common questions we hear at Churchfield Home Services is why External Wall Insulation doesn’t have a fixed price. The simple answer is that the cost depends on how much work your specific home requires.

External Wall Insulation covers the entire outside of a property, so size, shape, and access all play a major role. That’s why meaningful costs can only be confirmed once your home has been properly assessed.

What Makes Up the Cost of External Wall Insulation

External Wall Insulation is a large-scale upgrade, and the overall cost reflects several combined elements rather than a single item.

A significant portion of the cost comes from the insulation system itself, including the insulation boards, fixings, mesh, and protective render finish. Different finishes and thicknesses can affect both performance and price.

Scaffolding and access are another major factor. Homes with multiple storeys, extensions, or restricted access typically require more extensive scaffolding, which increases costs.

Labour and installation also form a large part of the overall figure. External Wall Insulation must be installed correctly to meet SEAI standards, manage moisture properly, and perform as intended over the long term.

Finally, there are design, compliance, and project management costs. At Churchfield Home Services, this includes proper planning, sequencing with other upgrades, and ensuring all works meet One Stop Shop requirements.
