Home Energy Model: replacement for the Standard Assessment Procedure (SAP)
Consultation description
Update: 1 March 2024
We have extended the consultation closing date to 27 March 2024 (from 6 March).
The Standard Assessment Procedure (SAP) is the methodology currently used by the government to estimate the energy performance of homes across the United Kingdom. It is of critical importance to the delivery of our housing and climate change objectives.
The Home Energy Model will replace the SAP for the energy rating of dwellings. It is still under development and we will implement the first version alongside the Future Homes Standard in 2025.
We are consulting on the Model while it is still at a formative stage, so that industry can participate in the development process. This consultation:
- summarises the development and validation work undertaken to date
- invites feedback to enable further model development in advance of its introduction
We will also hold a series of engagement events throughout the consultation period: email homeenergymodel@energysecurity.gov.uk to find out more.
The consultation will be of interest across the built environment sector.
It is part of a wider government package relating to the Home Energy Model and the Future Homes Standard:
- Future Homes and Buildings Standards 2023 consultation
- Home Energy Model: Future Homes Standard assessment consultation
- Home Energy Model: Future Homes Standard assessment consultation tool
