Government calculation method used to determine
the energy rating and carbon dioxide emissions for a residential dwelling.
Under Part L1A of the Building Regulations, SAP has been
mandatory for new build dwellings since April 2006, where the Dwelling Emission

Once the build is complete an Energy Performance Certificate (EPC) for each

If you are developing or designing residential units BBS can
provide a reliable and integrated SAP rating service wherever your project is
