How to Read an MOT History and What It Tells You
Buying a used car is an exciting moment, but before you hand over your hard-earned money, there’s one document that can tell you almost everything about a vehicle’s past: its MOT history. At Clovelly Cars, we believe every customer deserves full transparency, which is why we’re breaking down exactly how to read an MOT history and what it really tells you about a car.
What Is an MOT History?
Every vehicle in the UK over three years old must pass an annual MOT test to prove it’s roadworthy. Each test is logged on the government’s official database, creating a complete timeline of the car’s condition, mileage, and any issues flagged over the years.
The good news? This history is free and easy to check. Simply visit the GOV.UK MOT history checker, enter the registration number, and you’ll see every test the car has ever had.
What to Look For
1. Mileage Consistency
Each MOT records the car’s mileage at the time of the test. Look through the history and check that mileage increases steadily year on year. A sudden drop, a suspiciously low reading, or large unexplained gaps could indicate clocking (mileage fraud) or a car that’s been off the road for a long period.
2. Advisories
An “advisory” is a note from the tester flagging something that isn’t yet a fault but could become one, like worn brake pads or a slow tyre puncture. Advisories aren’t necessarily a red flag; almost every used car has some. What matters is whether the same advisory keeps reappearing year after year without being fixed, which suggests a lack of proper maintenance.
3. Failures and Reasons
If a car has failed its MOT in the past, the history shows exactly why. One or two minor failures over several years (corrosion on an exhaust, a bulb out) are completely normal. Repeated failures for the same serious issue – particularly around brakes, steering, or structural corrosion – are worth asking questions about.
4. Test Frequency and Gaps
Check that MOTs have happened roughly every year, as required. Long gaps between tests can mean the car was off the road (which isn’t necessarily bad) or that it was being driven illegally without a valid MOT (which is a concern).
5. Mileage vs. Age
Compare the average annual mileage to how the car has been used. A car doing 3,000 miles a year for a decade might have spent most of its life sitting still, which can bring its own issues, like perished rubber seals or a stiff clutch, even if the mileage looks low and appealing.
Why This Matters When Buying Used
An MOT history won’t tell you everything – it doesn’t cover regular servicing, for example, but it’s one of the most reliable free tools available to spot patterns, verify honesty, and avoid nasty surprises. Combined with a full-service history and a professional inspection, it gives you real confidence in your purchase.
