Why do I need a SAP?

The Building Regulations for England and Wales Compliance Part L1 require all new properties to be assessed using Standard Assessment Procedure (SAP) calculations for energy conservation. The SAP Assessment comprises a detailed report highlighting the Environmental Impact Rating (EIR) and the subsequent running costs of the dwelling.

Part L1 of the Building Regulations (England and Wales) also requires that the Dwelling Emission Rate (DER) should be equal to or lower than the Target Emission Rate (TER) for the dwelling and that the Designed Fabric Energy Efficiency (DFEE), should be equal or lower than the Target Fabric Efficiency (TFEE).The SAP Calculation is used to show compliance with this part of the regulations.

If you have a commercial property you need testing, instead of a SAP Assessment you will require a SBEM Calculation which we can undertake for you.

SAP Requirements

Are SAP Assessments the same as an EPC?

At the dwelling design stage your dedicated SAP Consultant will produce a Predictive Energy Assessment (PEA) highlighting those areas of the design which are crucial to ensure that you meet your Target Emission Rate. The Energy Performance Certificate (EPC) records a home's energy and CO2 emission performance. The certificate uses a scale from A to G to show the energy efficiency of the dwelling. A Band A dwelling is the most efficient and should therefore should save the most on energy bills.
