Home Energy Model (HEM) Assessments & SAP Transition Support
Competitive pricing from £150 (new-build SAP) / £220 (SBEM)
A More Detailed Way to Assess Home Energy Performance
The Home Energy Model is the next step in residential energy assessment in the UK. It has been developed to provide a more detailed view of how homes use energy, taking account of modern building design, low-carbon technologies and changing performance standards.
For project teams, this means energy compliance will become more data-driven, more detailed and more closely aligned with the way homes are expected to perform in real use.
HEM is not just a replacement for SAP — it represents a more advanced approach to understanding residential energy performance.
Better Insight for Modern Low-Carbon Homes
Modern homes are becoming more complex, with improved insulation, air tightness, heat pumps, solar PV, battery storage, smart controls and higher expectations around real-world performance. HEM is designed to support this shift with a more detailed modelling approach.
