Definition
The Completion Score reflects how complete a Property Passport is against a defined set of inputs (for example Documents, Media, and other checklist items the product tracks). It is a prioritisation tool, not a prediction.
What it helps with
- Sellers: a practical “what is still missing before good buyers feel confident.”
- Buyers: a quick signal for where to ask follow-up questions early.
- Agents: a consistent internal standard for sale readiness conversations without promising outcomes the product cannot control.
What it does not mean
A high score does not guarantee:
- a price,
- a mortgage,
- absence of defects,
- or zero legal complexity.
How to use it alongside professionals
Use the score to drive questions for your conveyancer and surveyor. The authoritative answers for title and condition remain in their workstreams.
