Home Energy Upgrade Grants for Sligo Homes has Expanded in 2026

Insulation still remains the fastest comfort upgrade

It reduces heat loss quickly and improves comfort before a heating upgrade. This also supports efficient attic insulation and cavity wall insulation in any project in sligo. First time buyers may access a higher fixed grant for attic insulation. And any qualifying household falls under the Warmer Homes Scheme. This makes sure a homeowner can access full funding for any specific measures.
