Recommendation 33

We recommend the EPC methodology is fundamentally overhauled to support low carbon heating measures by indicating, in its headline rating not only the fuel cost of heating a property but also its energy and carbon metrics. The measures in the Government’s EPC action plan are not enough to achieve what is needed to support the decarbonisation of homes: we recommend that Ministers look at this again with far greater urgency. Well in advance of 2025, while the energy market is rapidly decarbonising, we would like to see the introduction of EPCs more reflective of real-world performance, and the publication of regular updates on the developing methodology behind EPC assessments. Those carrying out EPC assessments should be suitably qualified and trained in energy modelling and assessment.
