SEAI Home Energy Grants
Every grant the Sustainable Energy Authority of Ireland pays on a home energy upgrade in 2026, and what each one is worth.
- €32,600 One Stop Shop Deep Retrofit Comprehensive whole-house retrofit through an SEAI registered One Stop Shop. Covers multiple measures to achieve a BER B2 or better.
- €14,500 Heat Pump System Grant for a heat pump system, including central heating upgrades and a bonus for replacing fossil fuel heating.
- €8,000 External Wall Insulation Grant for external insulation cladding on solid or hollow block walls.
- €5,600 Windows and Doors Grant for upgrading to energy-efficient windows and external doors.
- €4,500 Internal Wall Insulation Grant for internal wall insulation, also called dry lining, fitted to the inside face of external walls.
- €2,000 Attic Insulation Grant for attic or rafter insulation.
- €1,800 Solar PV Panels Grant for solar electricity panels, paid per kWp installed.
- €1,800 Cavity Wall Insulation Grant for cavity wall insulation using bonded bead or foam.
- €1,200 Solar Water Heating Grant for a solar thermal system that heats hot water for your home.
- €700 Heating Controls Upgrade Grant for upgrading heating controls including thermostats and zone controls.
Each figure is the maximum, which is the detached rate. SEAI sets most grants by dwelling type, so a semi-detached, terraced or apartment claim is lower. Each grant page carries all four.
