A Practitioner Study into the Variability of Domestic Energy Assessments

Gledhill, Toby; Swan, William; Fitton, Richard

Abstract

This paper focuses on the assessment of a domestic property’s energy performance status by a Domestic Energy Assessor (DEA), to ascertain the possible underlying reasons for variability in the results of Energy Performance Certificates (EPCs). By variability we mean discrepancies in assessment between different DEAs on similar properties. This is important because the uses for the EPC have been extended beyond their original function as an asset rating system, to include a wider range of themes encompassing issues such as building policy decisions, building performance, and the distribution of incentives and grants. As a consequence, inaccuracies in EPC reporting will have a greater impact than may have been the case at their outset.
