The Government has a vision for a reformed EPB framework that enhances progress already made in improving the overall framework that supports EPCs.
This reform aims to improve EPCs, DECs and TM44 inspections and update the framework to reflect modern policy objectives, make the regulation work better for businesses, and ensure the system works for UK markets.
This consultation seeks views on the reforms to the Energy Performance of Buildings (EPB) framework, applicable in England and Wales with an aim to provide an EPC system that provides a wider range of higher quality building performance data in a clear and accessible form.
Proposed metrics to measure energy efficiency used for EPCs
A proposed flexible approach for future energy performance metrics to replace the current EPC ratings. This aims to address concerns raised by the stakeholders including the Climate Change Committee regarding the limitations of the existing EPC system in supporting the transition to Net Zero.
The new approach would provide consumers with a wider variety of relevant metrics on Domestic EPCs to provide a more complete representation of buildings energy performance. They include energy cost and use, carbon, fabric performance, heating system and smart readiness.
Commercial Energy Performance Certificates, however, will likely maintain the single headline carbon metric in the short term, as they are already carbon focused and aligned with net zero objectives. It is acknowledged that new primary or secondary metrics could be added in time.
Additionally, the consultation suggests potential updates for future EPCs, which could include metrics related to a building’s resilience to climate change impacts, occupant health and wellbeing, biodiversity, and water efficiency.
Validity period of Energy Performance Certificates (EPCs)
At present, the validity period of an EPC is 10 years, and a valid EPC is required when a property is marketed for sale or let or is newly constructed.
The consultation now poses the question as to what the validity period for EPCs should be, presenting six different options, ranging from less than 2 years to 10 years. As it stands the validity period means EPCs may not reflect the current energy performance of a property, especially if energy efficiency improvements or changes in building use have occurred since the certificate was issued. A shorter validity could ensure EPCs provide more up-to-date and accurate information.
As well as the validity period, the government is also considering increasing the requirements for EPCs. One of the biggest proposals here includes the need for private landlords to get a new EPC when their current EPC has expired. This would support energy performance improvements in Private Rental Sector (PRS) buildings that are subject to Minimum Energy Efficiency Standards (MEES).
Other changes being proposed for commercial EPCs include:
- Using historical building data in future EPC assessments, potentially enhancing the understanding of building performance over time.
- Changes to ensure best practice on data use and storage.
- Make the registration on the EPB register mandatory.
How Simon McWhirter, deputy CEO of the UK Green Building Council, responded to the government’s consultation on the EPB framework.
EPCs are vital for understanding the impact our buildings have on our bills, our health, and our environment – this consultation is an important step towards updating a tool which will be crucial for meeting our net zero commitments, upgrading the quality of our built environment, and empowering individuals to transform their energy usage.
This consultation is due to close on 26 February 2025 and any new reforms to be applied throughout 2026.
