SAP Calculations

All new Domestic Buildings require SAP calculations under Part L of the 2006 Building Regulations.

SAP calculations provide an energy rating, based on the Thermal characteristics of the buildings fabric, internal measurements, heating and hot water systems and lighting. (as designed)

It is used to demonstrate compliance with Building Regulations Approved Document L1A by comparing the designed Dwelling Emission Rate (DER) with a SAP calculated Target Emission Rate (TER)

A further Dwelling Emission Rate (as built) takes into account any changes during construction.

When the dwelling is physically complete, the builder must obtain an EPC for the home; provide the EPC to the new owner of the dwelling; and notify Local Authority Building Control that this has been done. This must be done no later than five days after work has been completed. Once Building Control are satisfied the EPC has been properly produced and provided to the relevant party, they are able to issue a final completion certificate. FromĀ 6 AprilĀ 2008, a final completion certificate for a dwelling cannot be issued by building control unless they are satisfied an EPC has been provided.
