Standard Assessment Procedure - What You Need To Know


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 them as early in your project as possible, so if your building should fail, our team can advise you on how to improve.


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