MOT history went online for the public in 2015, when the government launched its free 'Check MOT history' service on GOV.UK. Anyone could then look up a vehicle's past MOT results using just its registration number. The records go back to 2005, when MOT testing in Great Britain was computerised.
Before that, a buyer had to rely on a stack of paper certificates, a seller's word, or a trip to the garage that did the tests. Now you can check a car's test record in a few seconds, from your phone, before you even go to see it.
The short timeline
- Before 2005: MOT results were mostly held on paper certificates and local records, so there was no national online record for buyers to check.
- 2005: MOT testing moved onto a central computer system. This is why online history today generally starts from this point, and why very old tests are missing.
- 2015: The public MOT history service went live, letting anyone view test results by registration number for free.
- 2018: The MOT defect categories changed to Dangerous, Major and Minor, alongside Advisory notes. Results from this point look different from older ones.
Exact launch dates for online services can vary depending on whether you count the beta or the full release. 2015 is the year most commonly cited for the public service.
What MOT history actually shows
A vehicle's online MOT record usually includes:
- Pass and fail results for each test, with dates.
- Odometer readings recorded at each test, which helps you spot odd mileage patterns.
- Failure reasons, such as worn brakes, tyres or suspension components.
- Advisories, which are issues the tester noted that were not serious enough to fail the car at the time.
- Expiry date of the current MOT certificate.
This is one of the most useful free tools a used-car buyer has. A pattern of repeated advisories about corrosion or worn parts that never seem to get fixed can tell you a lot about how the car has been looked after.
Why mileage history matters
Because the mileage is logged at every test, you can compare readings year by year. A car that records 60,000 miles one year and 35,000 the next deserves questions. This does not prove clocking, since typing errors happen, but it is a flag worth raising with the seller. Long gaps between tests or sudden drops in annual mileage can also be innocent, for example if the car was off the road for a while.
What MOT history does not tell you
MOT history is valuable, but it only covers what happens at the test. It does not tell you:
- Whether the car has been recorded as an insurance write-off (MIAFTR categories A, B, S or N).
- Whether the vehicle is marked as stolen on the Police National Computer (PNC).
- Whether there is outstanding finance secured against the car.
- How many previous keepers it has had.
- Whether the car has been imported, re-registered or had a plate change.
A car can pass its MOT and still have a hidden history. A repaired Cat S or Cat N vehicle, for instance, can be roadworthy on the day of the test. That is why MOT history is best used as one part of a wider check, not a replacement for one.
Coverage limits to be aware of
- New vehicles: Cars usually need their first MOT at three years old, so younger cars may show no history at all.
- Northern Ireland: Tests there are run separately, so the Great Britain service may not show the full picture for vehicles tested there.
- Exempt vehicles: Some older vehicles are exempt from the MOT, so there may be nothing to see.
- Test centre errors: Mileage and details are entered by people, so mistakes can appear.
How to use MOT history when buying
Start by checking the registration before you travel to view a car. Look at the pass and fail pattern, the advisories and the mileage. Then ask the seller about anything that stands out, such as a failed test followed by a quick pass, or the same advisory appearing several years in a row.
Next, go beyond the MOT. A fuller vehicle history check covers the things a test record cannot, including write-off category, stolen markers, outstanding finance and keeper changes. You can run the car's registration through motorpeek.com to see this kind of information alongside its MOT record. Motorpeek is an independent service and is not affiliated with the DVLA, DVSA or any government body.
Finally, remember that no check replaces a proper inspection. If you are not confident about what you see, consider a pre-purchase inspection from an independent mechanic.
The bottom line
MOT history has been available to the public online since 2015, with test records stretching back to 2005. It is free, quick and genuinely useful, but it only tells part of a vehicle's story. Use it to spot warning signs early, and combine it with other history checks before you hand over any money.
Frequently asked questions
When did MOT history go online in the UK?
The public MOT history service went online in 2015 on GOV.UK, letting anyone check a vehicle's test results using its registration number. The data it holds goes back to 2005, when MOT testing was computerised.
How far back does online MOT history go?
Online MOT history generally goes back to 2005 for vehicles that were tested in Great Britain. Tests carried out before the central computer system was in place will not normally appear, and cars under three years old may have no MOT record yet.
Is MOT history enough to check a used car?
No. MOT history shows test results, advisories and recorded mileage, but it does not show insurance write-off categories, stolen markers, outstanding finance or previous keepers. It is best used alongside a full vehicle history check and a physical inspection.
