What is a SAP Calculation?

SAP stands for Standard Assessment Procedure. You’ll need to provide these calculations if you’re building a new home or converting an existing building into a home. They measure the energy-related running costs of a home, and the assessments take into account heating, hot water, lighting and ventilation.

How are they calculated?

SAP is calculated using drawings and specifications at the design stage of a project. Once the project is completed, I finalise the assessment and provide ‘as built’ or ‘final’ stage SAP calculations. I can also undertake the air tightness test.

Why are SAP calculations required?

SAP calculations check that the building complies with Part L of Building Regulations. They also form part of the Energy Performance Certificate, and they help you understand how energy-efficient your building will be.

What else you might want to know…

I am an accredited SAP assessor. Over the years I’ve produced SAP calculations for all sorts of different buildings – from a one-off self-build ‘Passivhaus’ right through to large developments. And I don’t only do SAP calculations so that your building can get the necessary sign-offs; I can get involved right from the beginning to help you create an energy-efficient building with negligible running costs. Just get in touch and I can explain more.
