What Are SAP calculations

SAP stands for ‘Standard Assessment Procedure’. It is the only official, government approved system for assessing the energy rating for a new home. SAP assessors must be accredited and registered with a certification body.

A SAP Rating is a way of comparing energy performance of different homes – it results in a figure between 1 and 100+ (100 representing zero energy cost and anything over means you are exporting energy). The higher the SAP rating, the lower the fuel costs and the lower the associated emissions of carbon dioxide.

The SAP Calculations establish an energy cost based on the construction of the home, its heating system, internal lighting and any renewable technologies installed. It does not include energy used for cooking or appliances.
