MOT History Mileage Check — Verifying a Car's True Mileage
Every MOT test records the odometer reading at the time of the test. This creates a historical mileage trail that is an invaluable tool for verifying a car's true mileage and detecting odometer fraud.
How MOT Mileage Records Work
When a vehicle undergoes an MOT test, the examiner records the odometer reading as part of the test documentation. This is then uploaded to the DVSA database. The DVSA holds these records from 2005 onwards for most vehicles. Older records (pre-2005) are generally not available digitally.
The result is a time-stamped mileage record at (roughly) annual intervals for any car that has been regularly MOT'd. This data is available for free through the DVSA's check-mot.service.gov.uk or through VEHIXA's free vehicle check.
Reading the Mileage Trail
A genuine, unmanipulated mileage history should show consistent, logical increases year on year. The rate of increase should be broadly consistent — a car doing 10,000 miles a year should show roughly similar increments at each test.
Red flags to watch for:
- Mileage decrease — the mileage recorded at a later test is lower than a previous test. This is a definitive indicator of clocking. There is no innocent explanation.
- Suspiciously flat progression — the mileage barely changes between tests. A car that allegedly did only 200 miles in a year deserves scrutiny.
- Sudden large drop vs current odometer— if the last MOT shows 80,000 miles but the dashboard shows 45,000, the car has been clocked since the last test.
Legal Status of Clocking in the UK
Odometer clocking (deliberately altering a vehicle's recorded mileage) is illegal in the UK under the Consumer Protection from Unfair Trading Regulations 2008. Selling a clocked car while misrepresenting the mileage is a criminal offence that can result in prosecution and an unlimited fine. If you discover after purchase that a car was clocked, you have grounds for a civil claim against the seller.
Using the Data Before Buying
Before completing any used car purchase, compare the current odometer reading with the most recent MOT mileage record. If the seller claims the car has 45,000 miles but the last MOT three months ago recorded 68,000 miles, you have found a serious problem. Check this even when buying from a dealer — clocked cars appear at dealerships as well as in private sales.
Frequently Asked Questions
How do I check mileage history from MOT records?
Run a free check on VEHIXA or the DVSA's official check-mot.service.gov.uk. Both return the mileage recorded at every MOT test from 2005 onwards. You can then compare the progression against the current odometer reading.
What does it mean if the mileage decreases in MOT history?
A decrease in recorded mileage between MOT tests is a near-certain indicator of odometer clocking (winding back the mileage illegally). Odometer clocking is a criminal offence in the UK. Walk away from any car showing this pattern.
Can mileage be clocked without appearing in MOT history?
Yes. If a car is clocked between MOT tests, the previous MOT record will still show the original (higher) mileage, making the discrepancy visible. However, if the clock was wound back very recently and the car has not had an MOT since, the history check alone may not catch it — compare the seller's claimed mileage against the last MOT record.
How much mileage per year is considered high?
The UK average is around 8,000–10,000 miles per year for private vehicles. Cars that have done 15,000+ miles per year have often been used as fleet or high-use vehicles and may show more wear. Very low mileage (2,000 miles per year or less) on an old car can indicate periods of non-use, which brings its own risks (rubber degradation, brake corrosion).
Is MOT mileage data always accurate?
MOT mileage is recorded by the tester reading the odometer — it reflects what the car displayed on the day, not the true mileage if the odometer has been tampered with. This is why a sudden decrease in recorded mileage is such a reliable clocking indicator.
