You can apply for the Warmer Homes Scheme through the application information on the SEAI website, or contact SEAI directly on 01 808 2100 to discuss your circumstances. The scheme is intended to provide free energy upgrades to households meeting specific income and social welfare criteria, so eligibility is assessed individually. SEAI may request supporting information and arrange a home assessment before deciding which measures are suitable. Check the latest requirements and contact details on the official SEAI website, as the application process and criteria can change.
