SAP Calculations for Part L Compliance
We’re experienced in delivering SAP Calculations for new residential developments, as well as converted dwellings, extensions and conservatories for Part L1A and Part L1B compliance.
Part L1A SAP assessments before the start of site works for submission to Building Control. Upon completion, an as-built SAP calculation is completed.
Part L1B SAP calculations to assess the thermal efficiency of the proposed building fabric, along with the energy requirements of the heating, lighting, and hot water systems for converted dwellings.
Assessments for extensions and conservatories, including a notional SAP calculation based on the existing property with a conventional extension to the proposed dimensions, as well as a second extension SAP based on the proposed extension.
