The Standard Assessment Procedure (SAP) is the methodology used by the Government to assess and compare the energy performance of dwellings, and to assess compliance with Building Regulations Part L1.

SRE’s team of experienced and qualified in-house sustainability and energy consultants undertake SAP calculations and produce Energy Performance Certificates (EPCs) for both new-build and existing dwellings. By investing time and resources in keeping up to date with the latest technologies, calculation procedures and planning policies we are well placed to be able to advise clients on the most appropriate and cost-effective solutions for their projects.
