Where our data comes from
Free checks use the DVSA's MOT records and published government rules; paid checks add Experian's finance, theft and write-off records; valuations come from Brego.
Free check
- Vehicle details and MOT history: the DVSA MOT history service, read live when you check.
- Mileage analysis: our own, from the odometer reading at each MOT.
- ULEZ and clean air zones: the published standards of TfL, the councils and Scotland's LEZ scheme, applied to the car's fuel and registration date.
- Car tax: GOV.UK's vehicle tax rate tables, applied to the car's age, fuel and CO2.
- Recalls: the DVSA recall status on the MOT record.
- Reliability: our UK MOT Reliability Index, built from the DVSA's anonymised MOT test results (2022 to 2024).
Paid checks
- Finance, stolen, write-off, keepers, plates, colours, import, export, scrapped and VIN: Experian, through One Auto API. Reports say "Data provided by Experian" against these sections.
- Valuation: Brego.
