Example result
VAUXHALL ADAM
No mileage discrepancy found
Across 8 MOT readings, the recorded mileage only ever increased — a good sign. It doesn't rule out tampering between tests, but there's no obvious rollback in the official record.
Mileage at each MOT
The odometer reading logged by the test station at every MOT, from the official DVSA record.
First reading: 17,991 miles (October 2019)
Latest: 50,097 miles (November 2025)

How do I check a car's mileage?
How the mileage check works
Enter the reg
We look the car up instantly against the DVLA vehicle register and the DVSA MOT database — both official, both free.
See every MOT reading
You get the full MOT history: pass/fail, advisories, failures, and the exact mileage recorded at each test.
Get a clocking flag
We compare every mileage reading. If a later one is lower than an earlier one, we flag a possible discrepancy for you to question.
Why checking a car's mileage matters
Winding back an odometer — "clocking" — instantly makes a car look younger, less worn and worth more than it is. It's illegal to sell a clocked car without disclosing it, but cheap tools mean it still happens, and rising used-car prices make it worth a fraudster's while. A car showing 60,000 miles that has really covered 120,000 is due for major work its dashboard hides. A quick mileage clock check — comparing the reading logged at each MOT — is the simplest way to catch it.
The single best free defence is the MOT mileage trail. Because the reading is logged at every annual test, a rollback usually leaves a visible fingerprint — a later test showing fewer miles than an earlier one. That's exactly what this tool surfaces. For every pass, fail and advisory alongside the mileage, run the free MOT history check — or, if you only have the VIN, the free VIN check. For the fuller story, read our guides on how to check if a car has been clocked and how to read an MOT history.
The MOT trail has gaps: nothing before the first test at three years, and one reading a year after that. The manufacturer's dealer service records fill some of them, with the mileage logged at each dealer service — check the service history for £9.99, with nothing to pay if no records are found.
Mileage is one check. Here are the others
A clean mileage trail doesn't tell you whether the car is on finance, recorded as stolen or a repaired write-off. Our car check reads those records, using data provided by Experian, for £12.99 — or get it with the service history as a full vehicle check. It comes with Experian's Data Guarantee (up to £10,000 for 12 months; Experian's terms apply).

Mileage check — FAQs
How do I check a car's mileage?▾
Enter the registration in the free mileage check on this page. It reads the odometer reading recorded at every MOT on the official DVSA record, charts them in order and flags any reading lower than the one before — the classic sign of clocking. Then compare the latest reading with the clock on the car: it should be higher.
Is this car mileage check really free?▾
Yes. It uses official DVLA and DVSA data, which is free — there's no signup and no payment. We show the vehicle's details, its full MOT history including the mileage recorded at each test, and flag any discrepancy. The paid manufacturer service history is separate.
How do you detect a clocked car?▾
Every MOT test records the car's mileage. A car's odometer should only ever go up, so if a later MOT reading is lower than an earlier one, that's a mileage discrepancy — a classic sign of clocking. We compare every recorded reading and flag any that go backwards.
Does a mileage discrepancy always mean fraud?▾
No. Most backwards readings are suspicious, but some are legitimate — a replaced instrument cluster, or occasionally a data-entry error at the test centre. Treat a flag as a question to ask the seller, not proof of fraud. If they can't explain it with paperwork, walk away.
What's the difference between this and a full service history check?▾
This free tool shows the official MOT record and mileage trail. A full service history check (£9.99) adds the manufacturer's own dealer service records — the service dates, mileages and work done that aren't in the MOT data. Start here for free, then upgrade if you want the complete picture.
Can mileage be faked between MOTs?▾
Yes — this check catches rollbacks that show up in the official MOT record, but it can't see tampering done and undone between tests, or on a car too new to have MOT history. It's a strong first filter, not a cast-iron guarantee. Always combine it with an inspection.
Does a mileage check show a car's mileage before its first MOT?▾
No. A car's first MOT is due three years after it was first registered, so there is no MOT reading before then. Dealer service records often fill that gap: a service history check shows the mileage the manufacturer's dealers recorded at each service.
Does the mileage check show finance, theft or write-offs?▾
No. The mileage check reads the MOT odometer record only. Finance, police stolen and insurance write-off records come from our separate car check, using data provided by Experian (£12.99).
