Before you ask us.
What is SBEM and why do I need it for an extension?
SBEM is the commercial equivalent of SAP. A non-domestic extension generally needs an SBEM calculation (Part L2B) to demonstrate the works meet the energy requirements and to give Building Control the BRUKL output they expect.
How fast is it?
Most commercial SBEM calculations are produced within a few working days of receiving your drawings and specification. Working to a deadline? Tell us and we will prioritise your project.
What if the design changes?
Specification revisions are unlimited — change the fabric, glazing or services and we re-run the calculation at no extra fee per revision.
Can you do this anywhere in the UK?
Yes. We cover England, Wales, Scotland and Northern Ireland, with the equivalent energy standards handled under the same price.
