The assessor can be someone within the design team or work for the same company as the design team member(s) but the assessor must identify and manage any potential conflicts of interest. The assessor should also make BRE Global aware of the situation so that, should it prove appropriate, the certification report can be escalated to a more detailed level of quality assurance checking.
If the assessor is a member of the company who are producing evidence to demonstrate compliance, there must be clear separation of the roles and the BREEAM/HQM assessor must not be personally responsible for producing such evidence.
BREEAM/HQM is a 3rd party certification scheme. Therefore, it is important to avoid any conflicts of interest between those producing evidence and those awarding credits to ensure the robustness of the certification process.
