SAP Calculations & Energy Performance Certificates

A Standard Assessment Procedure (SAP) calculation is an energy rating which provides results of CO2 emissions and fuel costs for a dwelling.

The SAP rating scale is from 1 to 100+ or G to A and is a requirement under Part L1A and L1B. A SAP rating is required by building control at the development design stage along with a predicted energy certificate (PEA).

SAP ratings can only be provided by qualified Domestic Energy Assessors. The SAP calculation will then need to be finalised at the developmentā€™s as built stage and an Energy Performance Certificate (EPC) produced.

An EPC is a summary certificate based on the SAP calculation. It is required for selling a property and is required to be issued to building control.

SAP is also used within Part L1 building regulations compliancy for domestic dwellings. We offer a complete service for Part L1A & L1B compliancy through carbon dioxide emission rates (TER vs. DER). Not only will we provide you with your compliancy assessment but if required, recommendations and outline specification to achieve compliancy.
