Free MOT Check & Full MOT History by Registration

How to read an MOT history

The MOT record is the most useful free document that exists on a used car. Every roadworthiness test the vehicle has taken sits on the DVSA database: the date, the result, the mileage on the day, and the exact wording the tester used for anything they found. Read together, those entries tell a more honest story than any advert, any service receipt and certainly any seller.

Read it chronologically rather than by looking only at the most recent test. What you are looking for is pattern. An advisory that appears three years running was never repaired, only noted. A run of failures in consecutive years means the car has been kept on the road at the edge of the standard rather than maintained ahead of it. A long gap with no test at all means the car was off the road, and it is fair to ask why.

A suspiciously clean record on an older car deserves the same scrutiny as a bad one. A fifteen-year-old car with no advisories at all is unusual — it can mean careful ownership, but it can also mean test-centre shopping or, at the extreme, a cloned identity where the record belongs to a different car wearing copied plates. If the make, model, colour and first-registration date on the record do not match the car in front of you, walk away.

Pass, advisory, minor, major and dangerous: the defect categories

On 20 May 2018 the DVSA changed how results are recorded. Instead of a plain pass or fail, every defect is now graded by how serious it is. Knowing the five outcomes is what turns a list of entries into a judgement about the car.

• Pass — the vehicle met the minimum legal standard with no defects recorded at all.
• Pass with advisories — it passed, but the tester noted items that will need attention. Not faults yet; signals.
• Minor — still a pass. The defect does not significantly affect safety or emissions, but it should be repaired as soon as practical.
• Major — a fail. The defect could affect the safety of the vehicle, put other road users at risk, or harm the environment.
• Dangerous — a fail of the most serious kind. The vehicle must not be driven on the road until it is repaired, and the exemption that normally lets you drive to a garage does not apply.

Because the categories only exist from May 2018, tests before that date show as a simple pass or fail with advisory text. That is a limitation of the record itself, not a gap in this tool — anything older was recorded under the old scheme and cannot be re-graded after the fact. Our guide to MOT advisories and defect categories goes deeper on which ones actually matter when you are buying.

The mileage trail, and how it exposes a clocked car

Every MOT records the odometer reading on the day of the test, and that string of readings is the most reliable free mileage evidence in the UK. Genuine use produces a steady upward line. What you are hunting for is a reading that goes down between two consecutive tests, which is the single clearest signature of odometer tampering and shows up on most clocked cars. This tool flags that drop automatically rather than leaving you to spot it.

Implausibility matters as much as impossibility. A car averaging 12,000 miles a year that suddenly covers 1,800 in the twelve months before sale is worth a question, even though nothing about it is self-contradictory. So is a set of suspiciously round figures, and so is a very low total on a car whose condition does not match it.

The MOT trail has real blind spots. A car under three years old has no tests at all. A vehicle declared SORN, stored, or sold between tests can have a gap long enough to hide an adjustment. And the reading is typed in by a human at the test station, so genuine transcription errors do occur. If mileage is your specific worry, our car mileage and clocking check presents the same trail as a chart against the UK annual average.

When your MOT is due, and how early you can renew

The expiry date shown in your result is the date the current certificate runs out. You can take the test up to one calendar month minus a day before that date and keep the same anniversary, which is the single most useful rule in the MOT system: it gives you a month of slack to deal with a failure without shortening next year's certificate. Test earlier than that window and the new certificate simply runs twelve months from the test date, and you lose the difference permanently.

Most cars in Great Britain need their first MOT three years from first registration; Northern Ireland uses four years for cars and vans. Higher-risk classes such as taxis and ambulances are tested from one year old. Our guide on when your MOT is due works through the renewal window, first-test dates and what happens if you miss it.

MOT exemption and the 40-year rule

At the other end of a car's life sits the historic-vehicle exemption. Once a vehicle is more than 40 years old and has not been substantially changed in the previous 30 years, the registered keeper can declare it MOT exempt by signing a V112 declaration when taxing it. The rule is rolling, so the qualifying year moves forward annually.

Exemption removes the test, not the duty. The vehicle must still be roadworthy every time it is used, and the keeper remains liable if it is not. An exempt car that simply stops appearing in the MOT record is normal; an exempt car whose owner kept testing it voluntarily has given you a far better document to read, and plenty of careful owners do exactly that. The full rules — including what counts as “substantially changed” and how to declare exemption — are in the dedicated guide.

Driving without an MOT: fines, insurance and the two exceptions

Using a vehicle on a public road without a valid MOT carries a fine of up to £1,000. The practical risk is larger than the fine: most insurance policies require the vehicle to be roadworthy and legally usable, so an insurer can decline a claim, which turns a £1,000 exposure into the full value of whatever you hit. Roadside ANPR cameras check MOT status automatically, so the odds of going unnoticed are poor.

There are exactly two exceptions. You may drive to a pre-booked MOT test, and you may drive to or from a garage for repairs arranged in connection with one. Neither covers a car with a Dangerous defect recorded at its last test — that vehicle must be transported, not driven.

The test itself is capped by the DVSA at £54.85 for a class 4 vehicle, which is most cars and small vans, and £29.65 for a motorcycle. Garages routinely charge less than the cap, and a retest is free if the car is left with the same garage or returned within ten working days.

What the MOT does not tell you

The MOT is a minimum-standard roadworthiness test taken on one day of the year. It examines brakes, tyres, lights, steering, suspension, structure and emissions. It does not examine engine internals, the gearbox, the clutch, the cambelt, the air conditioning or the condition of any fluid. A car can pass an MOT on the morning its cambelt is a thousand miles overdue.

That is why a clean MOT history reads properly only alongside a service record. The MOT tells you the car was legal; the service history tells you it was looked after — which oil changes were done, at what mileage, by which dealer, and whether the manufacturer's schedule was actually followed. The two answer different questions, and the second is the one that predicts what the car will cost you.

Where this data comes from

Two sources, both official, both queried live at the moment you press the button. Vehicle identity, tax status and MOT expiry come from the DVLA Vehicle Enquiry Service. The test history, defect wording and odometer readings come from the DVSA MOT History API. Nothing is cached from a third-party aggregator and nothing is modelled.

Because the data is read live, the result reflects the record as it stood at the moment of the lookup. A test carried out that morning may take a short time to appear on the DVSA system. FindServiceHistory is an independent service and is not affiliated with the DVLA or the DVSA.

Every check has a link you can send

Once you run a plate, the result gets its own permanent address — /check-mot-history/YOURREG — so you can paste it into a forum thread, a WhatsApp message or an email to whoever is helping you decide. Whoever opens it sees exactly what you saw, with no signup and no paywall, and can share it onward themselves. It is the same free government data either way; the link just saves the next person typing the plate in again.
