Programs like the Better Energy Homes Scheme also offer additional financial support.
National Retrofitting Targets and Energy Efficiency
By 2030, Ireland aims to retrofit 500,000 homes to a Building Energy Rating (BER) of B2 or better and install 400,000 heat pumps for improved home efficiency.
Economic and Environmental Impact
The estimated total investment in energy efficiency improvements by 2030 is around €20 billion, with €11 billion allocated to home insulation.
Retrofitting helps reduce heating bills and contributes to lower carbon emissions, aligning with Ireland’s sustainability goals.
Detailed Cost Breakdowns
Window and Door Upgrades
- Double/Triple Glazing Windows: €600 – €1,200 per window
- Energy-Efficient Doors: €1,000 – €2,500
