Updated information on Standard Assessment Procedure

The government has published updated details about Standard Assessment Procedure SAP10.2 and the timeline for the Reduced data SAP (RdSAP).  

The Standard Assessment Procedure (SAP) is the methodology used by the government to assess and compare the energy and environmental performance of dwellings. Its purpose is to provide accurate and reliable assessments of dwellings that are needed to underpin energy and environmental policy initiatives. The Simplified Building Energy Model (SBEM) is the methodology used by the government to assess and compare the energy and environmental performance of non-domestic properties.

The most recent version of SAP 10 (10.2) came into force with the updated Part L building regulations in June 2022, and incorporated various changes to the methodology, including updated fuel prices, CO2 emissions and primary energy factors.
