Heat pumps and improved EPC ratings: Making them fit for purpose

Energy Performance Certificates (EPCs) have shaped the non-domestic built environment since their introduction in 2008 and, despite ongoing criticism, are clearly here to stay. While EPCs are often challenged for relying on simplified and sometimes outdated assumptions, overlooking factors such as heritage constraints and offering only a broad view of building performance, they continue to exert significant influence on investor confidence, tenant demand and asset value. This session explores whether EPCs are the right tool to drive progress towards net zero and, crucially, how they can be used more effectively.  Panel members will discuss how EPC assessments are approached in practice, the transformative impact of Minimum Energy Efficiency Standards (MEES), and recommended pathways for ongoing improvement. The discussion will cover practical measures to improve ratings, including the role of commercial heat pumps, and the differing levels of retrofit required to reach target ratings. Real-world case studies will demonstrate how office buildings can be upgraded from EPC ‘E’ to ‘A’ or ‘B’, contrasting deep retrofits in vacant buildings with the challenges of working in occupied spaces.
