FAQs: New digital service to improve energy efficiency performance

Propertymark’s response to the Department for Energy Security and Net Zero (DESNZ) consultation sets out a clear and urgent case for reform of the scheme, which provides financial support for households in England and Wales to install low-carbon heating systems like heat pumps or biomass boilers. A more ambitious scope is needed to help overcome the barriers landlords face in meeting the UK Government’s energy efficiency ambitions — especially the proposed Minimum Energy Efficiency Standard (MEES) of EPC C for new tenancies by 2028.

The UK Government has confirmed the change will be part of the upcoming Future Homes Standard, to be published this autumn. Propertymark supports efforts to reduce household energy costs and improve energy efficiency in new homes but has urged Ministers to address practical implementation challenges and ensure support is in place for the UK’s 29 million existing homes.

The Energy Security and Next Zero Committee (ESNZC) has published its first inquiry report on retrofitting homes, concluding that at the present rate of progress, the UK is far off track for meeting its legally binding commitment to reach net zero by 2050. Around 29 million homes require upgrades, but support schemes are too complicated, short-term, and are failing to engage consumers and the supply chain.

The Energy Performance Certificate (EPC) system will see the introduction of RdSAP 10 – an update to the methodology that underpins domestic energy assessments in existing homes. The changes are the most significant in over a decade and are expected to improve the accuracy of EPCs, better reflect how homes are used, and help inform decisions on energy efficiency. Nevertheless, some Propertymark members have already reported increased costs for the more detailed assessments.
