Standard Assessment Procedure (SAP 2009)
SAP 2009 information and downloads
The 2009 edition of the Standard Assessment Procedure (SAP 2009) will be introduced from October 2010 and will be used for compliance with building regulations in England & Wales (Part L) and in Scotland (Section 6) and for the generation of Energy Performance Certificates for new dwellings. Similar provisions will be made in Northern Ireland at a later date.
It is intended also to revise Reduced Data SAP, which is used for Energy Performance Certificates for existing dwellings, to align it with SAP 2009. That is likely to be implemented in 2011 and meanwhile RdSAP assessments will continue to be done using SAP 2005 (information about SAP 2005 and RdSAP 2005 is at www.bre.co.uk/sap2005).
