Why Choose us ?

We have delivered over 10,000 Energy Performance Certificates (EPCs)
We regularly work with Architects, Local Authorities and Private Developers.
We've worked in the EPC industry since its beginning in 2007

I love the process of seeing a new build project go from a design on paper to an energy efficient building ready for use. All our Energy Assessors are fully accredited with Elmhurst Energy, and are regularly independently audited for work quality and we post these results for transparency. You can read more about that here.

We really want and can help you on your next, or current project in any of the following ways:

SAP Calculations for New Build Projects
SAP Calculations for Extension Projects
SBEM Calculations for Commercial properties
BRUKL Certificates for Commercial projects
New Build EPCs (Energy Performance Certificates)
Excessive Glazing SAP Calculations (Guidance download here)
Water Efficiency Calculations (Approved Document G Building Regulations)
Setting up a professional construction project
Designing & implementing a realistic Construction Project Schedule

Meet the Team

Owner, Sap2Sbem

Justin Barker

Justin has been working in the Construction Industry since the late 1990's (giving away his age a bit there!) and the Energy Efficiency industry since 2007.

In 2022 at the end of the COVID pandemic Justin relocated to his wife's homeland, Spain, and regularly works on SAP and SBEM projects throughout England, Scotland and Wales.

Justin is a qualified Energy Assessor (dipOCDEA, dipNDEA, dipDEA, dipGDEA) for New Build SAP Calculations, SBEM Calculations for Commercial Buildings, New Build EPCs and Commercial EPC's. He is also a Internal Verifier for construction.

In his spare time he loves going to the beach, swimming in the sea, and giving as much time as possible to charity interests.

Justins passion is woodwork and antique furniture restoration, and at present is making a traditional Spanish guitar!

SAP Specialist
