The Scottish Government consulted on HEETSA to provide an option of retrofit properties going a step beyond the standardised method of EPCs. In our response to this consultation, we have expressed support for the principle of a government-led accreditation and approval framework to standardise retrofit assessments. Although the approach should be holistic, reflecting whole-building energy consumption and long-term carbon impact, not isolated works. Also, to streamline the process and control costs, it should be feasible for a single, well-qualified assessor to complete a HEETSA, given they receive appropriate training and qualifications. HEETSA should encompass the full retrofit process from assessment through to installation standards, while also considering factors like occupancy.
