# CarHistory.cc

> Free MOT history check for UK used-car buyers, and MOT pass rates by model and vehicle age from the DVSA's anonymised 2025 MOT test data. Independent site, not affiliated with the DVSA or GOV.UK. Figures are for guidance only.

## Tools
- Free MOT history check: https://carhistory.cc/ . Enter a UK registration to see the official DVSA MOT history explained: every result, fault and mileage reading, with mileage drops, dangerous defects in the last 3 years and repeated advisories flagged. The registration is used only to fetch that car's MOT records and never appears in a web address; see https://carhistory.cc/privacy/.
- Free car check by registration: what the free check shows (MOT status, every MOT result, defects and advisories, mileage drops, recall status, a comparison with the same model and year) and what it can't (finance, write-offs, theft, plate changes), next to the free GOV.UK tax and MOT history services: https://carhistory.cc/uk/free-car-check/
- Used car check, what to check before you buy and which checks are free: https://carhistory.cc/uk/used-car-check/
- MOT mileage check: https://carhistory.cc/uk/mot-mileage-check/
- When is my MOT due: a car's MOT expiry date, or a new car's first MOT due date, with the GOV.UK rules on testing early and on an expired MOT. We don't send MOT reminders: https://carhistory.cc/uk/mot-due-date/
- Car recall check: whether DVSA's record shows an outstanding recall for a registration (one of four states from the MOT history API's recall field; we don't list which recall it is), plus GOV.UK's make, model and year recall checker: https://carhistory.cc/uk/car-recall-check/
- Paid vehicle history checks compared (HPI, RAC, AA, Experian AutoCheck), using each provider's own published prices and coverage: https://carhistory.cc/uk/reports/

## Method
- Source: DVSA anonymised MOT tests and results, 2025 (Open Government Licence v3.0).
- First-time pass rate: initial tests passed with no repairs, divided by all initial tests. PRS counts as a fail, retests are not counted, class 4 vehicles only, grouped by the year the vehicle was first used. DVSA model names are grouped into model families.
