In-house teams can work well, but many installers hit capacity and consistency issues as volume rises. The key question is operational control, not just who attends site.

15,000+ surveys completed · structured pack on completion · EPC by next morning in the standard flow · portal/app workflow for team visibility.

Operational comparison

Where workflow quality is won or lost

Alternative model

Typical in-house pressure points

  • Capacity risk from holidays, sickness, and hiring lead time
  • Variable evidence quality across surveyors and handoff styles
  • Office/design teams chasing missing context during busy periods
  • Admin load increasing as pipeline complexity grows
Vertex model

Vertex Renewable Energy Surveys model

  • Structured evidence capture and repeatable pack format
  • Pack + organised photos available immediately upon completion of the visit
  • EPC by next morning in the standard flow
  • Portal visibility for office, design, and install teams
Commercial outcome
