MOT history is the public DVSA record of annual roadworthiness tests. Service history is the private record of maintenance kept by garages and owners. The MOT shows it passed; the service record shows it was looked after. Check both.

Two Different Records, Two Different Purposes
It is easy to treat service history and MOT history as the same thing, because both are about a car's past. They are not. The MOT history is a government record of an annual roadworthiness test, captured by DVSA and published for anyone to read. Service history is the trail of maintenance work, kept privately by the garages that did the work and the owners who paid for it. One is a pass or fail snapshot against legal standards; the other is the story of how the car was cared for.
- MOT history is a public record held by DVSA and viewable free at the GOV.UK check MOT history service; service history is private and held by garages and owners.
- An MOT proves the vehicle met roadworthiness standards on each test date; it does not prove the car was serviced or maintained between tests.
- The first MOT is due on the third anniversary of registration, so a car may have service records but no MOT history in its first three years.
- MOT history records the odometer reading at each test, which can be cross-checked against service invoices to verify mileage.
- Service history can take the form of stamps in a service book, dated invoices, or a manufacturer digital service record held electronically.
Understanding the difference matters most when buying a used vehicle. A car can have a flawless MOT record and still have been poorly maintained, because passing a test does not require that oil was changed, filters were replaced or worn parts were addressed before they became dangerous. Equally, a thick folder of service invoices says nothing about whether the car was roadworthy on any given test date. The two records answer separate questions, and a complete picture needs both.
What MOT History Tells You
MOT history records each test the vehicle has undergone since it became subject to MOT testing. For each test it shows the date, the result, the odometer reading, and any advisory notes or the reasons for a failure. Read as a sequence, this builds a timeline: how the car has aged, which faults recurred, whether advisories were left unattended, and how the mileage has climbed year on year. The presence of repeated advisories about the same component, for example, can hint at a problem that was never properly fixed.
What MOT history does not tell you is whether the car was serviced. The test checks roadworthiness against the DVSA criteria on the day, using the dangerous, major, minor and advisory categories introduced in May 2018. It does not record oil changes, cambelt replacements or routine servicing, and a car can pass while overdue for important maintenance. The MOT record is authoritative and free to access, but its scope is roadworthiness, not upkeep.
What Service History Tells You
Service history documents the planned and reactive maintenance a vehicle has received: oil and filter changes, brake work, timing belt replacement, fluid changes and the inspections a manufacturer schedules at set mileage or time intervals. A consistent service record suggests an owner who kept the car to schedule, which tends to correlate with better mechanical condition and fewer expensive surprises. It is the evidence that wear items were attended to before they failed.
Service records appear in several forms. A traditional service book carries dated stamps from the garages that carried out each service. Many cars instead come with a sheaf of itemised invoices showing the work and the mileage at the time. Increasingly, manufacturers keep a digital service record held on their own systems, accessible through a franchised dealer. None of these is published by the government, so unlike MOT history they rely on the documents the seller can produce and your ability to verify them.
| Feature | Service history | MOT history |
|---|---|---|
| Who holds it | Garages and owners (private) | DVSA (public record) |
| How to access | Service book, invoices, dealer digital record | Free at GOV.UK check MOT history |
| What it proves | Maintenance was carried out | Roadworthiness on each test date |
| Records mileage | Yes, on each invoice or stamp | Yes, at each test |
| Can be faked | Stamps can be forged, so verify | Hard to alter, held by DVSA |
How to Verify Service History
Because service history is private, it is only as good as the verification behind it. Stamps in a service book can be forged, so the sensible approach is to look for itemised invoices that name the garage, the date, the mileage and the work done. Cross-referencing those mileages against the odometer readings in the public MOT history is a powerful check: genuine records line up, while contradictions suggest the paperwork or the mileage has been manipulated.
Where a manufacturer keeps a digital service record, a franchised dealer can usually confirm the service entries against the vehicle identification number, which is harder to fake than a book stamp. It is also worth phoning the garages named on invoices to confirm they carried out the work. None of this requires special expertise, only a willingness to test the documents rather than take them at face value. The aim is to make sure the service story and the MOT timeline tell the same story.
Why a Buyer Should Look at Both
The two records cover each other's blind spots. The MOT history is reliable and independent but silent on maintenance; the service history covers maintenance but depends on documents that can be incomplete or falsified. Reading them together lets a buyer confirm that the mileage is consistent, that advisories raised at MOT were dealt with, and that the car was both roadworthy and looked after. A gap in either record is a prompt to ask questions rather than an automatic dealbreaker.
In practice, a thorough used-car check starts with the free MOT history on GOV.UK to establish the test record and mileage trail, then moves to the service documents to confirm the car was maintained to schedule. When the two agree, confidence rises. When they conflict, that conflict is itself the most useful information a buyer can have, and it is far cheaper to discover before purchase than after.
The relative weight of each record also shifts with the type of car. On an older, higher-mileage vehicle, a consistent service trail showing that wear items were renewed on schedule can matter a great deal, because neglected maintenance is what turns an ageing car into an expensive one. On a younger car, the MOT history may be short or absent because the first MOT only falls due on the third anniversary of registration, so the service record carries more of the story in those early years. Reading both records with the car's age in mind gives a more rounded judgement than treating either one as decisive on its own.
Frequently Asked Questions
What is the difference between service history and MOT history?
MOT history is the public DVSA record of annual roadworthiness tests, showing dates, results, mileage and advisories. Service history is the private record of maintenance work kept by garages and owners. The MOT shows the car passed its tests; the service history shows it was maintained. They prove different things.
Can I check a car's service history online?
Not in one central place. Unlike MOT history, service records are private and held in service books, invoices or a manufacturer digital service record. Some makers let a franchised dealer confirm digital service entries against the vehicle identification number, but there is no single free government service for service history.
Is MOT history the same as a full service history?
No. MOT history only records annual roadworthiness tests and does not show whether the car was serviced. A full service history is the separate record of scheduled maintenance such as oil changes and cambelt replacement. A car can have a clean MOT record yet no service history at all.
How do I verify a car's service history?
Look for itemised invoices naming the garage, date, mileage and work done, rather than relying on book stamps alone. Cross-check the mileages against the odometer readings in the public MOT history, and contact the garages named or ask a franchised dealer to confirm a digital service record.
Which matters more, service history or MOT history?
Neither replaces the other, because they answer different questions. MOT history is independent and reliable but covers only roadworthiness, while service history shows maintenance but depends on documents that can be incomplete. A careful buyer reads both and checks that they agree.
