What a MOT history check shows you
An MOT history check reveals every test result your vehicle has received from the DVSA (Driver and Vehicle Standards Agency), going back to when the car was first tested. The record shows the test date, whether the vehicle passed or failed, and — if it failed — what defects were found. You can see the exact mileage recorded at each test and whether any advisories were noted (minor issues that don't fail the test but should be watched).
This information is public and free to look up. You don't need to own the vehicle or have the owner's permission to check its history. The DVSA keeps these records for every car, van, and motorcycle that has been tested, and they remain on file even after a vehicle is scrapped or exported.
Key Takeaways
- You can check any vehicle's MOT history for free using the official DVSA website, which requires only the registration number.
- The record shows every test result dating back to the vehicle's first MOT, including pass/fail status, defects found, and mileage at test.
- A gap in MOT records means the vehicle was either not tested during that period or was off the road, which may indicate hidden damage or neglect.
- Advisories on the record are minor issues that didn't cause a failure but suggest maintenance may be needed soon.
- If you're buying a used car, checking the MOT history before viewing it can reveal whether the seller's claims about condition and mileage are consistent with test records.
How to run a free MOT history check
Go to the official DVSA website at check-mot.service.gov.uk. You will see a single search box asking for the vehicle's registration number. Enter the number exactly as it appears on the number plate — spaces and formatting don't matter, but the characters must be correct. Click "Search".
The results appear when ready. If the vehicle has a current MOT certificate, the page will show the expiry date and a green "Valid" label. Below that, you'll see a table listing every MOT test on record, with the test date, result (pass or fail), mileage, and a link to view the full defects list for that test. If the vehicle has never been tested or the registration number doesn't match any record, the page will say "No MOT test history found".
You can run this check as many times as you need. There's no limit on searches, and you don't need to create an account or provide any personal information.
What to look for in the results
Start by checking whether the MOT is currently valid. If the certificate has expired, the vehicle cannot legally be driven on the road unless it's being taken directly to a test centre for a new test. An expired MOT is a red flag when buying a used car, because it suggests the owner either forgot to renew it or knew the vehicle wouldn't pass.
Look at the pattern of results over time. A vehicle with a pass every year shows consistent maintenance. Repeated failures followed by a pass suggest the owner fixed problems between tests. A long gap in the record — say, two years with no test — means the vehicle wasn't tested during that time. This could mean it was off the road, exported, or scrapped, but it could also mean the owner straightforward didn't test it, which raises questions about what condition it was in.
Check the mileage progression. Each test records the odometer reading at that moment. If the mileage goes backwards between tests (for example, 50,000 miles one year and 45,000 the next), the odometer has been tampered with or reset. If the mileage jumps unusually high between tests, the vehicle may have been used for commercial purposes or long-distance work. Steady, gradual increases are normal.
Click on individual test results to see the full defects list. Advisories are minor — things like worn brake pads or a slow windscreen wiper — and don't prevent a pass. But if the same advisory appears year after year without being fixed, it suggests the owner isn't maintaining the vehicle properly. Major defects that caused a failure should have been corrected before the next test; if they appear again, something is wrong.
Understanding gaps and missing records
If a vehicle is more than 40 years old, it doesn't need an MOT at all, so you won't find a record. Vehicles under 40 years old should have a test every year once they reach three years old. If you see a gap of more than 12 months between tests, the vehicle wasn't tested during that time.
A gap doesn't automatically mean the vehicle is damaged or unsafe — it could straightforward mean the owner let the certificate lapse and then renewed it later. However, it does mean you have no independent record of the vehicle's condition during that period. When buying a used car, a gap is worth asking the seller about. Ask what the vehicle was doing during that time and whether it was driven or stored.
If a vehicle has no MOT history at all, it may be brand new (new cars don't need an MOT until they're three years old), or the registration number may be incorrect. Double-check the number plate and try again. If you're still getting no results and the vehicle is older than three years, contact the DVSA directly — the record may exist but the search tool may have a temporary issue.
Using MOT history when buying a used car
Check the MOT history before you arrange to view the car. This takes two minutes and can save you a wasted trip. If the MOT is expired, the mileage doesn't match the seller's claims, or there are repeated failures for the same defect, you already know something is off. You can then decide whether to ask the seller about it or look elsewhere.
When you do view the car, bring a printout of the MOT history with you. Compare the mileage on the odometer to the mileage recorded at the most recent test. If the car has been driven very little since the last test, the numbers should be close. A large difference could mean the odometer has been wound back. Also check the condition of items mentioned in recent advisories — if the record says the brake pads were worn, look at them yourself to see whether they've been replaced.
If the seller claims the car has been well maintained, the MOT history should back that up. A vehicle with a clean pass every year and no repeated advisories is a better bet than one with a patchy record. If the history shows a recent major repair (a failure followed by a pass), ask for the repair invoice to confirm the work was done properly.
What the MOT history doesn't tell you
An MOT pass means the vehicle met the minimum legal safety standard on the day of the test. It does not mean the car is in good condition overall, that it will be reliable, or that it hasn't been in an accident. The MOT only checks specific safety-critical systems: brakes, lights, steering, suspension, emissions, and a few others. It doesn't check the engine, gearbox, electrics, or interior condition.
A vehicle can pass its MOT and still have serious hidden problems. For example, a car with a failing engine could pass the emissions test if the fault hasn't yet triggered a warning light. A car with a gearbox on the verge of failure will pass because the MOT doesn't test gearbox performance in detail. This is why the MOT history is useful as one piece of information, but not the only one. Always have a used car inspected by a mechanic before you buy it.
The MOT history also doesn't show you maintenance records, accident history, or whether the car has been stolen or written off. For that information, you'll need to run a separate vehicle history check through a commercial service, though those are not free.
Frequently Asked Questions
Can I check the MOT history of a car I don't own?
Yes. The MOT history is public information and the DVSA search tool doesn't require you to prove ownership or get permission from the owner. You need only the registration number. This is why it's useful when buying a used car — you can check the history before you even contact the seller.
What does it mean if a vehicle has no MOT history?
It could mean the car is brand new and hasn't reached three years old yet (new cars don't need an MOT until their third birthday). It could also mean the registration number is incorrect, or the vehicle has been scrapped or exported. If you're checking a car that's older than three years and should have been tested, try the registration number again or contact the DVSA to confirm the record exists.
If the MOT is expired, can the car still be driven?
No. Once the MOT certificate expires, the vehicle cannot legally be driven on public roads except to take it directly to a test centre for a new test. Driving an expired MOT vehicle is an offense. If you're buying a car with an expired MOT, factor in the cost of a new test and any repairs that might be needed to pass it.
Does a pass on the MOT history mean the car is safe to buy?
A pass means the car met the legal safety standard at that moment, but it doesn't may provide the car is in good overall condition or that it hasn't developed problems since the test. Always have a used car inspected by a mechanic before you buy it, even if the MOT history looks clean. The MOT is a useful starting point, not a complete safety check.
Why does the mileage sometimes go down between MOT tests?
It shouldn't. If the odometer reading is lower at a later test than at an earlier one, the odometer has been tampered with or reset. This is illegal and a serious red flag when buying a used car. If you see this on an MOT history, don't buy the vehicle and report it to the police.
