SAP & EPC: Overview
The Standard Assessment Procedure (SAP) is the Government approved method for producing home energy ratings and allows developers and builders to demonstrate the energy efficiency of the new homes they build. Since 1st April 2006 a SAP calculation, compliant with part L1 of Building Regulations has been required for all new dwellings under European and UK legislation.
If you have built or are planning to build a new dwelling, then Part L of the Regulations states that you must now obtain a SAP rating for that dwelling. SAP assessments calculate a CO2 emission rating for the building. It is this rating that is submitted to Building Control for all new dwellings and which must meet the latest Building Regulation standards for energy efficiency.
