In short
- An MOT is a legal check on the day of the test. A service is upkeep, and it isn’t required by law[4].
- The MOT history is on GOV.UK. A service history isn’t: it comes from the seller, as a stamped book, invoices or a digital record[5].
- The MOT doesn’t cover the condition of the engine, clutch or gearbox[1]. A service record shows what maintenance was done.
- Read the two together. Service dates and mileages should fit the MOT mileages.
- “Full service history” is a trade phrase, and no official definition exists. If a car is advertised with one, ask to see the evidence[6].

An MOT is the yearly check that a car is safe and fit for the road. DVSA, the government agency that runs it, records every result. A service is routine maintenance done by a garage. The two answer different questions.
MOT history
You can look up a car’s MOT history yourself. The service history is usually the seller’s to show you. To see how the MOT record works, read how to check a car’s MOT history.
The MOT checks important parts of the car against legal standards[1]. Brakes, steering, tyres, lights, the exhaust and the fuel system are on the list[4].
It does not cover the condition of the engine, clutch or gearbox[1]. A test record also relates only to the testable items at the time of the test[3]. So a pass is a snapshot. It isn’t a guide to how the car has been looked after.
That is the gap a service history helps to fill. For the other things an MOT record leaves out, such as finance and write-offs, see what an MOT history can’t tell you.
A service is maintenance that helps a car run reliably. A full service usually includes an oil and filter change, and checks on things like the cooling system and the battery[4].
Makers set their own service schedules[6]. So what a service includes, and how often it is due, differs from car to car. Check the maker’s handbook for the car in front of you.
| Service | A common garage timing |
|---|---|
| Interim service | Every 6 months or 6,000 miles, whichever comes first A common number of checks: 50 checks |
| Full service | Every 12 months or 12,000 miles, whichever comes first A common number of checks: 77 checks |
The timings and number of checks RAC describes for garage services. They are not rules, and makers’ own schedules vary[4].
AA describes it as a car maintained to the maker’s service schedule, with the paperwork to show it[6]. It is trade wording, not a legal term. That means it can be used loosely.
AA splits it three ways.
- Full main dealer history. All the work was done at an approved dealer.
- Full history at another garage. The car was serviced to the maker’s guidelines, but not at a main dealer.
- Partial history. At least one service was missed.
If a car is advertised with a full service history, ask to see the evidence[6]. “Full” should be something you can check, not just something you’re told.
Evidence comes in three forms. A stamped service book is easy to check at a glance, but it can be lost or damaged. Invoices help rebuild a timeline of the work. Digital records are stored online against the car’s VIN, the long identity number on the V5C[5].
Digital records are updated by authorised service centres. If an independent garage did the work, you may need to contact that garage directly for its records[5].
AA says the two records work best together. The MOT shows how the car stood on the day of a test. The service record shows whether routine maintenance followed the maker’s advice[7].
Put the dates in order
List each MOT date and each service date. Look for services at regular intervals, with no long gaps[7].
Match the mileages
The mileage at each service should fit with the MOT mileages either side of it. If it doesn’t, ask why. Our guide to mileage clocking shows what to look for.
Match advisories to work
If an MOT advisory said the brakes were wearing, look for brake work in the service record. If the same advisory comes back year after year, ask whether it was ever put right.
Ask about anything that doesn’t fit
The seller may know which garage did the work. That garage may still hold a record it can share.
From age 3 to age 11, the middle mileage is roughly 6,000 to 8,000 miles higher for each extra year of age. This compares the middle mileage at one age with the next, from each vehicle’s latest 2025 MOT reading. Vans and motorbikes are in it. Source: MOT Wise analysis of DVSA MOT results, 2025.
That rise is under 12,000 miles. So for a vehicle with the middle mileage for its age, the 12-month mark usually comes first. Use these figures as a rough guide, not a rule. Every car is used differently.
Myth
A full service history means it passed its MOTs.
What's true
They are separate records. A service book doesn’t show MOT results, so check the MOT history on GOV.UK too.
Myth
An MOT checks the engine.
What's true
It doesn’t. The test does not cover the condition of the engine, clutch or gearbox.
Myth
A fresh MOT means the car has been serviced.
What's true
An MOT is not a service. A pass tells you about the testable parts on the day. It says nothing about whether servicing was done.
Myth
Skipping a service is against the law.
What's true
It isn’t. A service is recommended, not a legal requirement. A warranty may have its own rules about servicing, so read its terms.
AA lists a complete lack of service records among the patterns that deserve a closer look[7]. It doesn’t have to end the conversation. It does mean more questions, and more weight on what the MOT record shows.
- Ask what the seller knows: which garage looked after the car, and for how long they have had it. Citizens Advice says to ask about the service history[8].
- Ask for any invoices, even for single jobs.
- Ask a dealer for that make whether it holds a digital record under the car’s VIN. Full records often need the maker’s own portal or a call to the garages[5].
- Read the MOT history closely. Look for repeated advisories that no service record explains.
- Think about an independent inspection. Citizens Advice puts a report at around £120 to £250 (as of 10 October 2026)[8].
More questions to put to the seller are in questions to ask a seller.
Common questions
Does MOT history show service history?
No. The MOT history lists tests, not servicing. Service records come from the seller or the garages: a stamped book, invoices or a digital record.
What does full service history mean?
It usually means the car was serviced to the maker’s schedule, with paperwork to show it. It is a trade phrase, not a legal term, so ask to see the evidence.
Is a service a legal requirement?
No. An MOT is a legal requirement for most cars once they are 3 years old (4 in Northern Ireland). A service is recommended but not required by law. A warranty may have its own rules about servicing, so read its terms. This is general information, not legal advice.
How can I check a car’s service history?
Ask the seller for the service book, invoices or digital record. A dealer for that make may be able to look up a digital record from the car’s VIN. If an independent garage did the work, contact it directly.
Is an MOT the same as a service?
No. An MOT checks important parts against legal standards on the day. A service is maintenance. A pass doesn’t tell you whether the car has been serviced.
