A freelance surveyor can be useful for local cover or occasional overflow. The risk starts when every surveyor uses a different structure, different photo habits and different handover style. That creates hidden office work because the design team has to interpret the job before they can use it.

Vertex is built around repeatability. The survey, photo set, assumptions and actions are shaped for installer teams that need the same standard across heat pump, solar, battery and heat-loss work.

That consistency is the part that protects scale.
