Most SEAI grant routes require a BER assessment after the works, and whole-house schemes also require a pre-works assessment or home energy survey. Standalone solar PV grants do not require a BER.
For individual insulation and heating grants, SEAI generally requires a post-works BER so the improvement can be recorded. The cost of that BER is normally grant aided.
Under the One Stop Shop route, the provider carries out a technical survey and pre-works assessment to design the upgrade package, and a post-works BER to confirm the outcome. Solar PV applications are handled separately and do not require a BER.
