Your checklist should include confirming that the property and proposed wall insulation meet the current SEAI requirements, then choosing an SEAI-registered contractor. Ask for a written quotation, details of the insulation system, expected works, and any required pre- and post-works BER assessments. Keep your application reference, contractor paperwork, invoices, proof of payment and any documents showing property ownership or occupancy. Grant availability and eligibility can depend on the property, insulation type and application route, so check the latest guidance on SEAI’s official website before work begins.
