Why MOT history matters when buying a car

A single MOT test tells you whether a car passed or failed on one particular day. The full MOT history tells you a completely different story. It reveals patterns of maintenance, wear, and potential neglect that a test-day snapshot cannot show.

For example, a car might pass its latest MOT cleanly, but the history could show brake advisories appearing every year for four years, getting progressively worse. That pattern tells you the owner has been ignoring a deteriorating problem. Our analysis flags exactly this kind of issue automatically.

Mileage verification is another critical element. Every MOT records the odometer reading. By comparing readings across tests, we can detect sudden drops (clocking), suspicious gaps, or unusually low readings that suggest the car may have been tampered with.

Sample MOT advisory interpretation

Raw MOT text

Offside front brake disc worn, pitted or scored, but not seriously weakened (3.5.1g)

CarCostCheck interpretation

Brake discs are wearing out and will need replacing soon. Driving with worn discs increases stopping distances.

DVSA grade: AdvisoryEstimated cost: £150-£400Category: Brakes

MOT advisories, minor, major and dangerous defects explained

Every item in an MOT history carries one of four grades. Dangerous and major mean a fail; minor and advisory mean the car passed but the tester saw something. Our check shows the grade DVSA recorded next to each item, explains the common ones in plain English and puts a rough repair cost on them.

Dangerous (Fail)

A direct and immediate risk to road safety or the environment. The car must not be driven until it is repaired.

Major (Fail)

Could affect the car's safety, put other road users at risk or harm the environment. It needs repairing before the car can pass.

Minor (Pass)

No significant effect on safety or the environment. The tester must record it; fix it soon.

Advisory (Pass)

Not bad enough to fail yet, such as a part that is wearing. Optional for the tester, so worth watching from one test to the next.

What to look for in the advisories: the same item coming back test after test. Corrosion, brake discs, tyres and suspension bushes noted as advisories usually get worse, so an advisory that appears two or three years running is a repair the next owner will probably pay for. One that disappears at the next test was most likely fixed.

If a car fails, it can only be driven away if its current MOT is still valid and nothing dangerous was found. The MOT does not test the engine, clutch or gearbox, so a clean history says nothing about them.

Reading the mileage on an MOT history

Each MOT records the odometer reading on the day, so a car's history is also its mileage record. Three things are worth checking: every reading should be higher than the one before, the gaps between tests should look like normal use, and the latest reading should match the dashboard of the car you are looking at. A drop between two tests needs an explanation from the seller.

To judge whether a mileage is high or low for the car's age, here is the average reading at MOT tests carried out in 2024, from DVSA's own results.

First usedAverage mileage at its 2024 MOT
202128,500 miles
202034,500 miles
201942,300 miles
201850,600 miles
201759,400 miles
201667,300 miles
201482,100 miles
201294,100 miles
2010103,400 miles
2008110,400 miles
2006112,800 miles

DVSA anonymised MOT results for tests in 2024, cars (class 4), models with at least 30 tests, weighted by number of tests and rounded to the nearest 100 miles. The mileage check puts one car's readings on a timeline against these figures.

When the next MOT is due

A car needs its first MOT by the third anniversary of its registration, then one every year. You can have the test up to a month (minus a day) before the current one runs out and keep the same renewal date. The MOT history shows the expiry date of the latest pass; to look up a car's due date on its own, use when is my MOT due.

Frequently asked questions

How do I check a car's MOT for free?▼

Enter the vehicle's registration in the search box on this page. CarCostCheck instantly pulls the full official DVSA MOT history and shows every test, advisory and failure, plus mileage readings, with no payment and no signup. It is completely free to check any UK car's MOT history by reg.

Can I check MOT history by registration number?▼

Yes. Just type the number plate into the search box and you get the car's complete MOT history by reg in seconds: pass and fail results, advisories interpreted in plain English, and every recorded mileage reading. You do not need the V5C, MOT certificate number or any other detail, just the registration.

How far back does the MOT history go?▼

For cars, vans and motorcycles tested in England, Scotland and Wales, MOT history goes back to 2005. Tests done in Northern Ireland are only available from 2017. We analyse every test, advisory and failure in the vehicle's record.

What is the difference between an advisory and a minor defect?▼

Both mean the car passed that item. A minor defect has no significant effect on safety or the environment, and the tester must record it. An advisory is optional: the tester uses it for something that is not bad enough to fail yet, such as tyres close to the limit, so you can keep an eye on it. Major and dangerous defects are fails.

Can I drive my car if it failed its MOT?▼

Only if its current MOT is still valid and the test listed no dangerous defects, and it must still be roadworthy. Otherwise it has to be repaired first, apart from driving it to a pre-booked MOT or to be repaired. Driving a car that failed because of a dangerous defect can mean a fine of up to £2,500, a ban and 3 penalty points.

Does the MOT history show the mileage?▼

Yes. Every MOT records the odometer reading, so the history gives one mileage reading per test. Our check puts them on a timeline and flags any reading lower than the one before, which can mean the mileage has been wound back, a new instrument cluster, or a typing error at the test.

What is an MOT advisory?▼

An advisory is an issue noted by the tester that is not serious enough to cause a failure today, but could become a problem in the future. Common examples include worn brake discs, slight corrosion, or tyres approaching the legal limit. We explain common advisories in plain English and put a rough repair cost on each one.

Can I check MOT history on the GOV.UK website?▼

Yes, GOV.UK shows raw MOT test data. However, it does not interpret advisories, estimate repair costs, detect mileage clocking, or provide a reliability score. CarCostCheck analyses the same data and gives you actionable insights rather than raw technical codes.

What does the MOT history tell me about a car's condition?▼

MOT history reveals patterns that a single test cannot. Recurring brake issues suggest neglect. A string of advisories that never get fixed indicates a cost-cutting owner. Mileage readings that drop between tests suggest clocking. We flag all of these automatically in every report.

Is the MOT history check free?▼

Yes, completely free. The MOT history analysis, including common advisories explained, repair cost estimates, mileage verification, and reliability scoring, is all included at no cost. No signup or email required. Enter a reg plate and get results instantly.

How do you interpret MOT advisories?▼

We match the tester's wording against the most common MOT items, such as brakes, tyres, suspension, steering, exhaust and corrosion, and explain each one in plain English with a rough repair cost. For example, a brake disc that is worn, pitted or scored becomes a note that the discs will need replacing soon, with an estimate of £150-£400. Items without a specific note show the tester's own words with a general estimate. Every item keeps DVSA's own grading: advisory, minor, major or dangerous.
