Apply through the Warmer Homes Scheme section of the SEAI website, using the application form and providing details about your home, household and any qualifying social welfare payment. SEAI reviews the application and may ask for supporting documents before deciding whether it can proceed. If your application is accepted, SEAI may arrange a home energy assessment and identify suitable upgrades, with work carried out through its approved process. Eligibility, the upgrades offered and the timing depend on your circumstances, property and available funding, so check the latest guidance directly with SEAI.
