Is External Wall Insulation Worth It in Ireland?

When External Wall Insulation Is Worth It

• Older detached and semi-detached homes
• Properties with solid block or stone walls
• Homes where cavity wall insulation is not possible

In these cases, wrapping the home externally can be far more effective than relying on internal measures alone. However, it is not suitable for every home, which is why proper assessment is essential.

How Grants Affect the Value

External Wall Insulation is supported through the Sustainable Energy Authority of Ireland (SEAI) under the One Stop Shop Home Energy Upgrade pathway.

Grant support of up to €8,000 may be available when External Wall Insulation is included as part of a qualifying whole-home upgrade. At Churchfield Home Services, we manage this process for you, from assessment through to grant application and installation.

Grants are deducted upfront, reducing the amount you pay and helping make the investment more manageable.

Why It’s Not Always the Right First Step

While External Wall Insulation can be highly effective, it is not always the best starting point. Some homes achieve excellent improvements through attic insulation, cavity wall insulation, or ventilation upgrades first.

A Home Energy Assessment carried out through Churchfield Home Services looks at your home as a whole. This ensures External Wall Insulation is recommended only when it makes sense and when it will work properly with other upgrades.
