The National Residential Retrofit Plan 2026 strengthens SEAI support that can reduce the cost of insulation, heat pumps and energy efficient windows and doors for Sligo households and supports home energy upgrades in Sligo.
Sligo has a wide mix of housing types, from older coastal and rural homes to estates from the 1970s to 2000s and newer builds. Exposure to wind and damp conditions can also increase heat loss which makes the right sequencing of upgrades especially important. The best plan depends on your build type, current insulation levels and heating system and your current BER upgrade Sligo starting point. This update helps make the right upgrades more affordable and easier to plan for retrofit projects in sligo.

A key change is the enhanced Heat Pump System Grant, now supporting up to €12,500 made up of:
✔ €6,500 for the heat pump
✔ €2,000 for radiator and pipework upgrades
✔ €4,000 renewable heating bonus
For Sligo homeowners, the biggest advantage is improved affordability for replacing older boilers where the home is suitable and correctly prepared for a heat pump upgrade.

The plan includes increased grants for attic and cavity wall insulation. For many Sligo homes, insulation is often the best first move.

First time buyers may access a higher fixed grant for attic insulation and qualifying households under the Warmer Homes Scheme can access full funding for specific measures.

In Sligo, a new grant is being introduced for energy efficient windows and doors where the building fabric meets a minimum performance standard. This can be especially relevant for homes with draughts and condensation, but it works best when paired with the right insulation plan and a window replacement grant route if applicable.
👉 Book an assessment to confirm if window upgrades are recommended and grant eligible.
