How to check a car's MOT for free in the UK
What is MOT, what MOT history reveals and how to detect a clocked odometer — everything you need to know before buying a used car in the UK.
What is an MOT test?
MOT (Ministry of Transport) is a mandatory annual roadworthiness test for most cars over three years old in the UK. It checks whether the vehicle meets minimum safety and environmental standards. Driving without a valid MOT is illegal — it carries a fine of up to £1,000 and the vehicle can be seized.
Tests are carried out at DVSA-approved garages (Driving and Vehicle Standards Agency), and results are stored in the UK government's publicly accessible database.
MOT history is free
Unlike a finance check, MOT history is publicly available through official government data. You can check it for any car using the registration number.

How to spot a clocked odometer from MOT history
Clocking is illegal and still widespread on the UK used car market. MOT history is the best tool to catch it — mileage is recorded at every test. If you see mileage decrease between tests, or stay suspiciously flat over years — that's a serious red flag.
| Year | Recorded mileage | Note |
|---|---|---|
| 2020 | 22,000 | ✓ |
| 2021 | 34,500 | ✓ |
| 2022 | 47,100 | ✓ |
| 2023 | 38,200 | ⚠ Mileage drop |
| 2024 | 41,800 | ⚠ Suspicious |
What do advisory notes mean?
Advisories are items flagged by the inspector as needing monitoring — not serious enough to fail the car, but signalling wear that will likely need attention soon. They don't prevent a pass, but they're important.
- One advisory is normal and usually nothing to worry about
- Repeated advisories across multiple tests suggest the owner has been ignoring known issues
- Advisories about tyres, brakes, or steering are serious — these are safety-critical components
- Use advisories as a negotiating tool — get repair quotes and factor them into the price
What if a car has no MOT history?
Cars under three years old have no MOT history — they don't need one yet. If an older car has no history, it could mean:
- An imported car, only recently registered in the UK
- A number plate change to hide earlier history
- The car was on SORN (off the road) for an extended period
- Used exclusively on private land
