How can I verify a car's true mileage?

Check the DVSA MOT history for free at gov.uk/check-mot-history. Every MOT test records the odometer reading. Compare each year's reading — mileage should increase consistently over time. Any decrease, suspicious drop, or implausibly low reading compared to vehicle age is a strong indicator of clocking.

What is odometer clocking?

Clocking is the practice of illegally winding back or resetting a car's odometer to show a lower mileage than the vehicle has actually covered. It inflates the apparent value of the car and is illegal under the Fraud Act 2006 in the UK.

What is considered high mileage for a used car?

The average UK car covers approximately 10,000–12,000 miles per year. A 10-year-old car with 100,000–120,000 miles is around average. Mileage below 8,000 per year may suggest the car has been lightly used or potentially clocked. Consider total mileage, age, service history, and condition together rather than mileage alone.

Can a car have genuine low mileage?

Yes. Some cars genuinely cover low mileage — retired owners, second cars, or vehicles used mainly for short trips. Genuine low mileage should be consistent across all MOT records and corroborated by service history stamps, wear to pedals, steering wheel and seat bolster condition.

How to Verify Mileage Using MOT History

Every UK MOT test records the odometer reading at the time of the test. The DVSA makes this data freely available at gov.uk/check-mot-history.

What Clocked Mileage Looks Like

Mileage drops between tests

Odometers can only physically decrease if wound back. Any decrease in recorded mileage is definitive evidence of clocking.

Implausibly low readings

A 10-year-old car with 30,000 miles needs explanation. Check the service history for corroboration — service intervals are mileage-based.

Large gaps between tests

A car with no MOT records for several years may have been SORN'd, or the records may have been suppressed to hide suspicious readings.

Mileage inconsistent with wear

Worn pedal rubbers, seat bolsters, and steering wheels on a claimed low-mileage car are physical evidence against the odometer reading.

Average Annual Mileage in the UK

The UK average is approximately 8,000–12,000 miles per year for private vehicles. Company cars and diesel vehicles typically cover more. Use this as a rough benchmark:

5-year-old car: approximately 40,000–60,000 miles is normal
10-year-old car: approximately 80,000–120,000 miles is normal
Significantly less than this warrants closer scrutiny

Corroborate With Service History

Service stamps record mileage at each service. These provide an independent cross-reference to the MOT readings. If a service record at 80,000 miles is followed by an MOT at 60,000 miles, the car has been clocked.
