New Build Residential (Part L1)

As of the 15th June 2022 Part L1 2021 requires all new domestic dwellings to prepare a SAP10 calculation in order to demonstrate that the dwelling’s energy emission rate (DER) is lower than a target emission rate (TER). This is also sometimes referred to as an energy report. The process involves a set of desktop calculations prepared using drawings and specifications. Part L requires that the SAP calculation must been submitted to the building control officer prior to commencement of any works onsite.

For further information about the new SAP10 methodolgy and the the 2021 Regulations and the changes its likely to have on new projects, visit our 2021 Building Regulations Page for further information and guidance.

Our experienced team of SAP accredited energy assessors are able to work with you to ensure that your project not only passes the DER/TER requirement but does so in the most cost effective manner possible. Our approach for every project is to provide a bespoke solution customised for every client and their project. Our solutions have helped clients save many thousands of pounds which has forged long lasting relationships.

All Design Stage SAP Calculations include a Predicted Energy Assessment (PEA) which is required for marketing and selling a dwelling off plan.

 

Upon completion of a dwelling and confirmation of the actual build specification the "As Built" SAP calculation is produced which is then used to prepare the Energy Performance Certificate (EPC) for the dwelling.

Don't forget! Use our New Build Pack service to save money and hassle by combining your SAP, EPC, Air Permeability Testing, Extract Ventilation Testing, Water Efficiency Calculation and Acoustic Testing (if applicable) all together.
