SAP Calculations
Energy assessments for new and existing homes to ensure Part L compliance.
What Are SAP Calculations?
SAP (Standard Assessment Procedure) Calculations measure the energy performance of new-build homes and are required for Building Regulations Part L compliance. We provide fast, accurate assessments to help developers, architects, and homeowners secure approval with no delays.
Why SAP Calculations Are Required
SAP Calculations ensure new homes are energy-efficient, environmentally responsible, and compliant with national standards. Without SAP, developments cannot proceed or be signed off.

Frequently Asked Questions
Some frequently asked questions about the service that you may have questions about
What is a SAP calculation and when do I need one?
A SAP (Standard Assessment Procedure) calculation measures the energy performance of a dwelling. It’s required for all new builds, conversions, and certain extensions to show compliance with Building Regulations Part L.
What’s the difference between SAP and SBEM calculations?
SAP is used for residential buildings, while SBEM (Simplified Building Energy Model) applies to non-domestic buildings such as offices, schools, or retail units.
When should I carry out a SAP or SBEM assessment?
Ideally, during the design stage — early assessments help identify cost-effective ways to meet energy targets and avoid redesigns later.
What information do I need to provide for an energy assessment?
We typically require architectural drawings, construction details, heating and ventilation specifications, and window/lighting information. Our team can guide you through exactly what’s needed.
