GrantWise Team: Eligibility usually depends on the property, the applicant and whether the installation follows SEAI scheme rules. Typical checks include owning or legally occupying an eligible home, meeting the scheme’s property requirements, using an SEAI-registered contractor and getting grant approval before work begins. You may not qualify if the property or installation has already received certain public funding, or if the work does not meet the technical requirements. SEAI makes the final decision, so check the current rules on its official website or ask your registered installer to confirm your circumstances.
