Mileage checks: the latest reading and its limits

When available, CarCheck displays the last-test odometer reading published in the government dataset. This is one latest recorded reading, not an annual mileage history or a measurement of today’s mileage.

Exactly what the report provides

The mileage source publishes the latest reading without its own measurement date. The last-test date shown in the vehicle timeline comes from the vehicle registry. The sources can update at different times, so compare them with the vehicle documents.

The history dataset describes coverage of active private vehicles from 2017 onward. A missing reading does not mean the vehicle has never been driven or tested.

How to use the reading

Compare it with the dashboard, advert and dated service invoices. A current reading below the published figure needs an explanation: reporting errors, instrument replacement or an altered reading are possible. The report alone cannot establish the cause.

Without multiple dated readings, you cannot reconstruct mileage for each year or establish that the odometer was never altered. Matching figures also do not establish an accident-free history or sound mechanical condition.

If estimated annual mileage is shown, it divides the latest reading by the time since first registration, ending at the last test when its date is available or at the lookup date otherwise. This is a calculated average for that period, not a separately measured reading for each year.

Illustrative example — fictional data

The dataset shows 120,000 km but the dashboard shows 112,000 km. Request an explanation and documents before proceeding. If the dashboard shows 128,000 km, the difference is simply 8,000 km; it does not reveal the distance covered in each year.

Your next step

Find the latest recorded reading, photograph the dashboard with the seller’s permission and compare dated invoices. Resolve unexplained discrepancies before buying.

Frequently asked questions

Does CarCheck show mileage from every test over the years?

No. The source currently used publishes the last-test reading. Look for older readings in retained vehicle documents and service invoices.
