Standard Assessment Procedure (SAP) is the UK government's national calculation methodology used to demonstrate a building's compliance with Building Regulations. In Wales, new builds must comply with Part L of Building Regulations similar to properties in England.
Two SAP Calculations need to be performed: Design Stage (before the building is constructed) and As-Built (after construction).
The building must meet 5 main criteria:
All new dwellings, extensions and conversions which result in a material change of use of a property, must have a SAP calculation in order to demonstrate compliance with Building Regulations. However, there are a few notable exceptions.
The following buildings do not require a SAP calcultion:
Conservatories are exempt if they are under 30m2 with walls, windows and doors retained from the original property that separate it from the main house. If the original ones are removed and replaced by others that meet the energy efficiency requirement, and providing the heating system of the main house does not extend into the the conservatory, it is exempt. The same rule applies for porches.
