More about SAP Calculations

A SAP calculation is an energy rating, which provides results of CO2 emissions and fuel costs for a dwelling. The SAP rating scale is from 1 to 100+ or G to A and is a requirement under Part L1A and L1B.

All new buildings will need to be assessed under the new Part L1A 2010, from October 1st 2010. For the new L1A regulations a SAP calculation will be required at the design stage to provide to building control along with a predicted energy certificate.

These can only be provided by a qualified On Construction Domestic Energy Assessor. The SAP calculation will then need to be finalised at the As Built Stage and an EPC will then be provided. An EPC is a summary certificate based on the SAP calculation. It required for selling a property and is now required to be shown to building control.
