You will generally need documents confirming your identity, home ownership and entitlement to a qualifying social welfare payment or other income-related support. SEAI may also request household income details, your property and contact information, and a recent electricity or utility bill. The exact documents can vary depending on your circumstances and the upgrade being considered, so check the current SEAI application guidance before applying. SEAI and its appointed assessors decide whether the home qualifies and which works are suitable.
