Part L & SAP calculations

What are SAP calculations?

SAP calculations (Standard Assessment Procedure – sometimes referred to as SAP ratings) are a measure of the energy use and carbon emissions of new dwellings. They are a government-defined process in accordance with Part L of the Building Regulations.

Why must I have a SAP calculation?

All new-build residential dwellings require a SAP calculation to demonstrate compliance with Part L of the Building Regulations. When submitting plans Building Control will ask the architect or developer for a SAP calculation at both Design Stage,before any work begins on site, and on completion of the build. If you cannot provide one, your building project will not be able to progress.
