SAP Calculations for new-build dwellings, conversions and extensions in England​

All new buildings in England and Wales are required to have a Standard Assessment Procedure (SAP) calculation, which measures the property’s energy performance for heating, lighting, and ventilation. The calculation also considers the fabric and structure of the building, the type and efficiency of insulation, and any renewable technologies installed.

Why SAP Calculations Are Required

SAP Calculations are used to demonstrate compliance with Part L1 of the Building Regulations. They are required for all new dwellings, including home conversions, and some extensions.

How Our SAP Calculations Work

Our SAP Calculations are carried out off-plan, so no site visit is required. We therefore cover the whole of England (please see areas we cover).  To complete the assessment, we ask you to provide:
  • Detailed floor plans and building layouts
  • Building specifications
  • Construction notes

Once the SAP Calculation is finalised and the building is complete, we can produce an As Built EPC (On Construction EPC) for your property.

Our Commitment to Sustainability

We are an eco-aware company and strongly support the fight against climate change. By helping properties meet building regulation energy targets, we contribute to reducing carbon emissions within the construction and property industry. With renewable technologies increasingly shaping housing design, this is an exciting and progressive time for sustainable building.
