You will generally need the completed SEAI application form, proof that you receive a qualifying social welfare payment, and documents confirming your identity, address and home ownership. SEAI may also ask for a recent electricity bill, property details or other information to confirm that the home meets the scheme requirements. The exact documents can vary depending on your circumstances, so check the current guidance on the official SEAI website before applying. SEAI makes the final eligibility decision and may request further evidence.
