Standard Assessment Procedure (SAP 10)
This site hosts documents and information relating to version 10 of the Standard Assessment Procedure (SAP 10).
Please note that versions 10.0 and 10.1 of SAP must not be used for any official purpose.
SAP 2012 must continue to be used for Building Regulation compliance and for producing Energy Performance Certificates until further notice, in conjunction with the 2006 edition of BR443 (for calculating U-values).
SAP 10.1 was published in October to coincide with the publication of the UK Government’s Future Homes Standard consultation and the Welsh Government’s Building Regulations Part L and F consultation, which discuss proposed changes to Building Regulations Approved Documents, making reference to SAP. We anticipate there will be a further update to SAP (to version 10.2) following these consultations, prior to its official use. Any future updates will be added to this webpage.
The SAP 10.1 specification document can be downloaded from the link below.
A software implementation of SAP 10.1 for the UK Government’s consultation is available here.
A software implementation of SAP 10.1 for the Welsh Government’s consultation is available here.
