Data Sources
Last updated · 19 June 2026
A displayed field can come from a government lookup, a contracted history-data provider or a calculation over returned records. Those are different relationships. This page describes the integration category without claiming direct register access, an official partnership or universal coverage where the project evidence does not establish one.
Vehicle registration details
The free lookup requests available identity and status fields from configured UK vehicle lookup services. Make, model, colour, fuel, registration dates, tax or current MOT fields are shown only when returned. The service does not infer a missing field.
MOT history
MOT test dates, results, odometer readings, advisories and defects are requested through the configured MOT-history integration. The page shows the records returned at check time. No record returned is not described as a clean MOT history.
Paid vehicle-history fields
Finance, insurance write-off, stolen, high-risk and status fields are requested through the contracted vehicle-history integration for the tiers that include them. The upstream source of an individual field is named publicly only when current supplier documentation and permission to make that attribution are held.
Availability states
Each check can be included and completed with no adverse record, included but unavailable for that vehicle, temporarily unavailable from the supplier, or not included in the chosen tier. These states are not interchangeable. Missing data is shown as unknown or not returned, never as clear.
Calculations and interpretations
Mileage anomaly indicators compare returned odometer readings. Scores and summaries explain only the groups that could be assessed. A valuation, if returned for an eligible report, is labelled as an estimate and is not generated when required provider fields are absent.
What we don’t do
- We do not describe supplier access as direct access to an upstream register unless that relationship is documented and approved for publication.
- We do not claim an official partnership merely because an integration returns a field.
- We don’t guess. If a register doesn’t hold a record, we say so on the report — we don’t invent “no issues found” copy to fill the gap.
