BREEAM AP/Sustainability Champion appointment timing

It is acceptable for the BREEAM AP/Sustainability Champion to beΒ appointed later than the required stage, if it can be demonstrated that the AP/Sustainability Champion was appointed at the earliest appropriate time in the project and that the late involvement willΒ not have a detrimental effect on theΒ setting of BREEAM performance targets that need to be formally agreed no later than the concept design stage.
