SAP stands for Standard Assessment Procedure and is a method of calculating the energy efficiency and energy use of a dwelling. It is from this calculation that an Energy Performance Certificate (EPC) is created. An EPC is required for every new build and refurbished property, and a design stage SAP assessment is needed to be signed off by building control before you start on site.

MACH Energy offers fully accredited ‘design stage’ and ‘as built’ SAP assessments, as well as EPCs for either new (Part L1A) or refurbished (Part L1B) dwellings. The MACH service ensures that you will not just receive a pass or fail mark, but will be offered pragmatic and detailed advice on how to improve the design, with input on the varius methods on how this can improvement can be carried out.

Get in touch if you are looking to get a quote for your project or just have some questions about which performance targets apply to your project.

Do you need a SAP assessment and EPC for your project?

SAP calculations are carried out early on in the design stage to ensure that the proposed dwelling is in line with the requirements set out within Approved Document L1A or L1B.
