You generally need to use an SEAI-registered One Stop Shop, which assesses your home and manages the upgrade from planning through to completion. The property and applicant must meet the relevant SEAI scheme rules, which can include conditions on the dwelling’s age, ownership or occupancy, and the measures being installed. The provider normally arranges a pre-works BER assessment, recommends a suitable package, applies for eligible grants, and organises a post-works BER. Requirements and grant outcomes depend on your circumstances, so confirm the details with the registered provider and check the latest guidance on the official SEAI website.
