UKBC are registered SAP Assessors with Stroma.

Standard Assessment Procedure

SAP stands for ‘Standard Assessment Procedure’. SAP calculations are designed to measure the energy performance of all new dwellings, conversions and extensions.

You need these calculations to make sure your building complies with Part L (England & Wales), Section 6 (Scotland) or Part F1 (Northern Ireland) of the most recent version of The Building Regulations. Introduced by the government in 1995, these laws are concerned with the conservation of fuel and power. It is recommended that you get your SAP calculations as early in your project as possible, so if your building should fail, our team can give you advise you on how to improve.

UKBC offers both L1A and L1B SAP calculations for new builds and extensions and conversions respectively.


UKBC’s service includes:

  • Target Emissions Rates (TER) and Target Fabric Energy Efficiency (TFEE) calculations
  • Dwelling Emission Rate (DER) and Dwelling Fabric Energy Efficiency (DFEE) measurements
  • Energy Performance Certification (EPC)
  • Comprehensive support and guidance throughout the entire SAP process, with consultancy and design advice included in the price.
