RegFlags checks any UK car or van’s MOT history for free, with mileage analysis, red flags, comparisons with similar cars and a plain-English report, plus a full vehicle check for outstanding finance, theft and write-offs.
Every report is built from the car’s own MOT history and DVSA’s published data. These screenshots use made-up example cars.
Put in a number plate and RegFlags reads every MOT the car has had since 2005. You get a RegFlags Rating out of 100, red, amber and green flags, and the figures that matter: MOT expiry, mileage, first-time pass rate, ULEZ and how many are still on the road.
A plain-English summary, then the good signs and the watch-outs, with flags that say what to dig into and what to ask about. The summary is written by AI from the car’s own record, and it only explains facts RegFlags has already worked out: it never makes up figures.
Each odometer reading from every MOT on one chart, with average and recent miles a year, and a check that the mileage only ever went up.
Defects noted at more than one MOT are tracked as still present or since fixed. Every defect is grouped by system, such as brakes or suspension, and set against how often similar cars fail there.
Each report turns the car’s own history into questions to ask the seller and things to check on the test drive, so you go to the viewing prepared.
Compare cars side by side, each against the others and its model average, with the best figure in each row highlighted.
Save your cars and RegFlags reminds you 30, 7 and 1 days before each MOT, by email or push. Watch cars you’re thinking of buying and hear when they have a new MOT.
Stock, listings, photos, your own website, leads, invoicing and handover in one place, with MOT history on every car you sell.
Ask follow-up questions and get answers drawn from the car’s MOT record.
Save a report as a PDF or share a link with someone helping you choose.
See how models compare at the MOT, built from DVSA’s anonymised test results.
A full MCP layer lets Claude, ChatGPT and other assistants check and compare cars, ask about a report, fetch the PDF and look after your garage, all from the conversation.
Bulk checks, an API, branded PDF reports and team seats for dealers and traders.
Outstanding finance, stolen and write-off checks, keeper and plate changes, and a VIN match.
Yes. Checking a car’s MOT history is free, and you don’t need to sign up. See regflags.co.uk for the current plans.
From the DVSA’s MOT history service, which covers cars and vans tested in Great Britain since 2005, and DVSA’s anonymised MOT results for comparisons with similar cars.
Buyers get a clear picture of a car before they part with their money: its MOT record, mileage, recurring problems and, when they need it, a full check for finance, theft and write-offs. Dealers get the same data built into everything they do, with their stock loaded from their own website, MOT history on every car, and listings, websites, leads, invoicing and handover in one system.
