Check that your home and planned external wall insulation work fit the current SEAI Home Energy Upgrade Grant rules, and confirm whether a pre-works BER or technical assessment is needed. Get a written quote from an SEAI-registered contractor covering insulation thickness, ventilation, finishes and any associated work. Apply through the correct SEAI route before starting, keep the approval and invoices, and arrange any required post-works BER assessment. GrantWise is independent, so SEAI and your registered contractor must confirm the applicable grant and your individual eligibility.
