Wall insulation quote FAQs
How much is the SEAI wall insulation grant in 2026?
It depends on the method and home type. Cavity wall grants run €700–€1,800, internal (dry-lining) €1,500–€4,500, and external wall insulation €3,000–€8,000 — the top of each range applies to detached houses. Always confirm current rates on SEAI.ie.
Cavity, internal or external — which do I need?
It depends on how your walls were built. Homes with a cavity can usually take pumped cavity fill (the cheapest route). Solid-wall homes need internal dry-lining or an external wrap. If you’re not sure, pick “Not sure yet” — contractors assess the wall type as part of quoting.
Is this quote service really free?
Yes. Contractors pay us a fee for introductions — homeowners never pay anything and are under no obligation to accept any quote.
