These provide information which is a mandatory requirement for any new build dwelling or new dwellings created by conversion.

SAP is used to show compliance with Part L of the Building Regulations and is applied at the design stage of the build process. It calculates the energy cost and carbon emissions generated to heat, light, ventilate and provide hot water to a dwelling.

LABC has launched a suite of 250 Registered Construction Details (RCDs) to help you combat the problem of cold bridging in construction that will minimise heat loss through the weak junction points in a building’s outer envelope. 

The ESconsult SAP team are fully qualified assessors. We can provide:

  • A SAP and EPC for new build dwellings or dwellings which have been converted. 
  • SAP calculations for substantially glazed extensions where the amount of glazing exceeds 25% floor area.

The amount you pay reflects the level of service required and is per dwelling
