The Standard Assessment Procedure (SAP) is the UK government's approved methodology for calculating the energy performance of dwellings. A SAP assessment is required for new dwellings and determines the dwelling's CO2 emissions rating, which must meet building regulations. A SAP assessment typically takes 2 working days and the cost depends on the dwelling's size and complexity. The assessment identifies improvements needed if a dwelling fails and how to enhance its rating through better construction materials, insulation, air tightness and efficient heating.
