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.
