SAP Calculations

Building a new home involves meeting strict energy‑efficiency standards outlined in the building regulations under Part L of the Building Regulations. Before construction begins, every new dwelling must undergo SAP calculations to ensure the design is compliant.

What SAP Calculations Do

- Confirm that your new build complies with Part L requirements.

- Assess insulation, heating, ventilation, and overall energy performance.

- Provide the SAP score, predicted EPC rating, and compliance reports needed for Building Control.
