Standard Assessment Procedure (SAP)

The Standard Assessment Procedure (SAP) is a UK-based method used to calculate the energy efficiency of residential homes. It assesses how well a building retains heat and minimizes energy use for heating, hot water, and lighting. The SAP score helps determine a property's environmental impact and energy costs, guiding improvements and verifying compliance with regulations. It considers factors like insulation, heating systems, windows, and overall design to provide a standardized rating, making it easier for homeowners, builders, and authorities to understand and compare the energy performance of different homes.
