2.5 Million Vehicle Mileage Check

Please note: we have since released a bigger test in September 2020 when we tested the mileage of 7 million vehicles

Vehicle mileage issues and clocking can be a problem for used car buyers., We have done this test to get an idea of how many vehicles have mileage discrepancies (the more data the better the picture).

What counts as a mileage discrepancy?

When the mileage has been lowered between MOT tests.

When there’s a mixture of miles and kilometre unit readings.

We offer the same mileage check as we carried out on this test for free, and you can check your vehicle in seconds below:

Explanation of the above data:

  • Make & Model – Vehicle make and model.
  • Total Failed – How many failed out of the Total Checked for this make + model.
  • Total Checked – The total checked from the 2,500,000 list.
  • Fail Rate – The fail percentage for the make + model (worked out using Total Failed and Total Checked data)

Average Annual Mileage of Passed VS Failed Vehicle

Just like we did in the 1 million mileage test, we compiled the average yearly mileage of vehicles that passed VS vehicles that failed. This is what we found.

Average Yearly Mileage of Passed Vehicle (2,339,570 Passed):


Average Yearly Mileage of Failed Vehicle (160,430 Failed):


Estimated Vehicles With Mileage Discrepancies in the UK

Below we have worked out the estimated number of vehicles in the UK with mileage issues. According to racfoundation.org there were 38.7 million vehicles as of June 2019.

The overall failure percentage in this test was: 6.41%

More information about this data

How was this test carried out?

We used a large list of vehicle registrations and ran them through our custom software, this took some time do, but gave us the data we needed for this research.

Where is the mileage data from?

We used the gov.uk MOT API to collect the mileage data.

Why so many vehicles?

The more data the better, it gives a clearer picture of mileage discrepancies if we collect more data. So, we tried our best to collect as much as possible.
