Energy Performance of Buildings (Scotland) Regulations 2025: non-domestic buildings research

This research presents an illustrative comparison between the Energy Performance Certificate (EPC) ratings of five archetypal non-domestic buildings in Scotland when calculated using the current and revised rating systems.


Appendix A

We understand that an analysis by the Scottish Government on the public datasets of the Scottish non-domestic EPC Registry, summarised in Table 5, has indicated that the majority of buildings are likely to perform better (i.e., achieve a better rating/band) under the new, comparative rating system compared to the current absolute rating system.

Table 5: Scottish Government’s analysis results of building performance under current and new EPC rating systems
Performance Number of buildings
Comparative band better 40,295
Comparative band worse 14,374
Comparative band and absolute band the same 18,083
