What are SAP Calculations?
Code for Sustainable Homes Assessments
SAP is the Government’s Standard Assessment Procedure for Energy Rating of Dwellings. SAP is adopted by government as part of the UK national methodology for calculation of the energy performance of buildings. It is used to demonstrate compliance with building regulations for dwellings – Part L (England and Wales), Section 6 (Scotland) and Part F (Northern Ireland) – and to provide energy ratings for dwellings.
From 6 April 2008 it is law to provide an Energy Performance Certificate for all new and newly built homes that are completed after that date. Regulations have been made under sections 58B and 58C of Finance Act 2003 to permit relief from Stamp Duty Land Tax for zero-carbon new homes. First the dwelling CO2 emissions are calculated as for building regulations compliance. The calculations are then continued as described in the document “SAP 2005 extension for SDLT”. The conditions for SDLT relief are:
- The heat loss parameter must be no greater than 0.8 W/m?K.
- The DER must be no greater than zero.
- The net CO2 emissions must be no greater than zero.
When is an SAP Calculation required?
Design Stage – Building Control require a Design Stage SAP Calculation to be submitted with your Building Regulations Application. Without the SAP Calculation, Building Control will not allow the project to start on site.
As-built Stage – Building Control require an As-built Stage SAP Calculation and EPC when the building is completed. Without this info it is unlikely that the building will achieve Final Building Control approval.
SAP Calculation Procedure:
- Review your plans & specification and make any recommendations
- Complete the Design Stage SAP Calculations
- Provide guidance to achieve a pass (if required)
- Complete the As Built SAP Calculations and EPCs
- Supply all documents to meet your deadlines.

SBEM – Simplified Building Energy Model
Simplified Building Energy Model (SBEM) calculations are required for all newly built commercial & industrial structures.
SBEM is a calculation of the energy efficiency and carbon emissions performance of commercial structures. In accordance with Part L Regulations, your Building Control Officer / Approved Inspector will require a SBEM report at the same time as your Building Control Application – this first part of the SBEM procedure is called the ‘design’ stage. The second stage of the SBEM procedure is called the ‘as-built’ stage and is completed when the building is finished.
- New build commercial/industrial/non-domestic buildings
- Extensions to commercial/industrial/non-domestic buildings
