Standard Assessment Procedure (SAP)

The Standard Assessment Procedure (SAP) is the methodology used by the Department of Energy and Climate Change (DECC) to assess and compare the energy and environmental performance of dwellings. The SAP is mandatory under Regulation L of the building regulations for newly built dwellings, which includes any new dwelling that is formed either by construction or by conversion.

Its purpose is to provide accurate and reliable assessments of a dwelling's energy performances. SAP works by assessing how much energy a dwelling will consume and how much carbon dioxide (CO2) will be emitted in delivering a defined level of comfort and service provision, based on standardised occupancy conditions. This enables a like-for-like comparison of dwelling performance.

SAP quantifies a dwelling's performance in terms of: energy use per unit floor area, a fuel-cost-based energy efficiency rating (the SAP rating) and emissions of CO2. Our newly qualified assessors will provide all the necessary assessments for you to submit to the body who is providing you with the Building Regulation approval. 

We offer a friendly and reliable service and are happy to provide quotes when multiple tests are required, which can be offered at a discounted rate. Please use our energy enquiry form for one of our qualified assessors to get in touch.
