There is no single SEAI insulation grant amount: support varies according to the insulation measure, property type, energy upgrade route and your circumstances. Published rates may apply to attic, cavity wall, internal wall, external wall or floor insulation, while some households may instead qualify for support through the Warmer Homes Scheme. Check the latest rates and conditions on the official SEAI website, as these can change and approval is not automatic. A registered contractor can assess your home and confirm which grant, if any, may apply.
