The UK Government has published a partial response to its consultation on reforms to the Energy Performance of Buildings (EPB) regime. These reforms will shape how Energy Performance Certificates (EPCs) are produced and used in the coming years, supporting national goals around decarbonisation, energy efficiency and reduced running costs. At Galaxy Technical Services, we are closely monitoring these developments to ensure our customers are fully prepared for the changes ahead.
EPCs play a key role in property sales, lettings and compliance, yet they have often been criticised for offering limited practical insight. The government’s consultation focused on improving what EPCs measure and when they are required, helping EPCs better reflect real building performance and support net zero targets. This partial response covers the first phase of reform, with further guidance and regulation expected from 2026.
One of the main reforms is the move towards multiple performance metrics, particularly for domestic properties.
Future domestic EPCs are expected to include:
A carbon emissions metric will remain as a secondary indicator.
For non domestic buildings, a single carbon based headline rating is expected to remain, supporting business reporting and sustainability objectives.
This approach provides a more balanced view of building performance and reduces reliance on energy price fluctuations.
The government found limited support for shortening the current ten year EPC validity period, due to concerns over cost and administrative burden. There were also mixed views on requiring EPCs at the start of every new tenancy.
While no final decisions have been made, the focus remains on improving accuracy without placing unnecessary pressure on landlords or property owners.
The transition to the new EPC system will be supported by updated regulations, guidance and alignment with the new Home Energy Model. These changes are expected to be introduced from 2026 onwards.
At Galaxy Technical Services, we are already preparing for this transition. This includes reviewing our assessment processes, investing in staff training, and ensuring our systems are aligned with emerging government standards. Our goal is to provide consistent, compliant and high quality EPC services throughout the changeover period.
We will also be supporting our customers with clear advice on how the new metrics may affect their properties, helping them identify practical improvement measures and plan future upgrades.
For developers and housebuilders the reforms will create stronger links between building performance and measurable outcomes.
Galaxy Technical Services will continue to work closely with clients across all sectors, providing guidance, assessments and support. Via our experienced and knowledgeable team of Technical Services Managers and our bespoke SAP App.
The government’s partial response confirms a clear commitment to modernising EPCs and improving the way building energy performance is measured. While further details are still to come, change is firmly on the horizon.
Galaxy Technical Services remains committed to staying ahead of these developments and helping our customers navigate the transition with confidence and clarity.
