Yes. Anyone can run a full check a day without signing up. A free account gives you 3 a day (including any you ran before signing up), the full report and MOT reminders. Paid plans are only for people who check a lot of cars.

MOT history comes live from the DVSA's official MOT History API. Comparisons with similar cars use DVSA's anonymised MOT dataset, and "still on the road" figures come from Department for Transport licensing statistics.

The summary is AI-assisted. It's written from facts we've already worked out from the MOT record, and every number in it is checked against the data before you see it. If anything doesn't match, you get a standard summary instead.

No. RegFlags uses MOT, recall and licensing data. It doesn't cover outstanding finance, theft or insurance write-offs, which need a paid history check from a specialist provider.

Our 0 to 100 score for how reassuring a car's MOT record is. Every car starts at 100 and loses points for specific, listed reasons such as dangerous defects, recurring problems or a mileage inconsistency. It describes the record, not the car in front of you.

Yes. Create a free account, add your car to your garage and we'll email you 30, 7 and 1 days before its MOT is due.
