SAP Calculations

The Standard Assessment Procedure (SAP Calculation) is the UK Government’s approved methodology for calculating the energy performance of new built of converted dwellings.

For compliance with Building Regulations PART L 2010, SAP calculations are required for all new dwellings together with the ones that have been created through material changes of use involving building work and extensions over certain sizes (consult with your building control authority for this requirement).

A SAP EPC report is generated through the use of Government Approved software and technical calculations to produce a Predicted Energy Assessment (PEA) and an On Construction Energy Performance Certificate (OCEPC) both of which are reports evaluated from the supporting SAP Calculations.

SAP Ratings

The indications of energy performance are energy consumption per unit floor area, an energy cost rating ( the SAP Rating), an environmental impact rating based on CO2 emissions and a Dwelling CO2 Emission Rate (DER).

The SAP rating reflects on the dwelling’s energy costs associated with space heating, water heating, ventilation and lighting minus the cost savings from energy generation technologies. The SAP report is expressed on a scale of 1 to 100.

We are Nationwide service provider for Standard Assessment Procedure SAP Calculations, SAP Report, SAP Certificate, Predicted Energy Assessment PEA Certificate and Energy Performance Certificate EPC for new built dwellings. can provide Standard Assessment Procedure Calculations (SAP Calculation) for both SAP 2005 and SAP 2009. We also produce On Construction Energy Performance Certificates for new build dwellings.
