What is SAP / New Build EPC?

A Standard Assessment Procedure or (SAP) EPC refers to an Energy Performance Certificate issued by an ‘On Construction Domestic Energy Assessor’, using SAP methodology and software.

Any new dwelling, or dwellings created by conversion or change of use are required to have SAP calculations carried out which differs from the most common EPC called Reduced SAP (or RdSAP) . The EPC assessor will need to use architects plans and drawings, together with detailed information about the construction, heating and ventilation amongst others in order to produce an EPC outlining the energy efficiency of that build. SAP EPC's are also vlaid for 10 years unless any improvements have been made to the home in the meantime or the owner is applying for Green Deal finance.
