An SEAI One Stop Shop is an SEAI-registered provider that can coordinate several home energy upgrades, such as insulation, heating improvements and solar PV, through one project. It typically arranges the assessment, grant application, contractors, works and follow-up BER assessment, although the exact service varies between providers. The provider applies relevant SEAI grant support to the project, while the homeowner usually pays any remaining balance. Grant amounts, eligible measures and approval depend on the property and the work proposed, so check the details with the provider and on the official SEAI website before signing a contract.
