SEAI Grants

The SEAI (Sustainable Energy Authority of Ireland) is a grant system whereby you can receive a cash grant for upgrading the energy efficiency of your home. This is in the form of a tax credit at 13.5% of qualifying expenditure. The minimum spend is €5000 and the max is €30,000. The aim of the grant is to improve energy efficiency in homes across Ireland. This in turn benefits you by maintaining the energy in the home and reducing heating costs. Our doors and windows are covered by the scheme and can help improve the value of your home too. Using less energy means less CO2, so you will be doing your bit for the environment too!
