The Government is committed to reducing emissions from the residential sector through retrofitting the equivalent of 500,000 homes to a Building Energy Rating B2/cost optimal level and installing 400,000 heat pumps in existing homes to replace older, less efficient heating systems by end-2030.
Last year, the Government launched a range of enhanced supports to make it easier and more affordable for homeowners to retrofit their homes. In addition to 100% funded retrofits for energy poor households, grant supports are available for those seeking to undertake deep retrofits as well as for homeowners that wish to take a step by step approach by installing individual or shallow measures.
I am not aware of any restrictions which would prevent a homeowner with a D1 BER standard home or lower BER standard from applying for an SEAI home energy efficiency upgrade. Further information on all SEAI schemes can be found at www.seai.ie.
