Memo

Update: 1 March 2024 We have extended the consultation closing date to 27 March 2024 (from 6 March). The Home Energy Model: Future Homes Standard assessment is the methodology which will be used to demonstrate that new dwellings comply with the Future Homes Standard. It will replace the Standard Assessment Procedure ( SAP ) version 10.2 for the energy rating of dwellings. The Home Energy Model: Future Homes Standard assessment is still under development and we will implement it 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 work undertaken to date; and 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 of material relating to the Home Energy Model and the Future Homes Standard.
