A mileage check compares the odometer reading on a used car with the readings recorded at each MOT test, so you can see whether the figure on the dashboard fits the vehicle's history. The Driver and Vehicle Standards Agency (DVSA) stores an odometer reading with every MOT result in Great Britain, and a free mileage checker built on that record lets you view it by registration number in seconds.
Part of Used Car History. Start with the main guide: Car Finance Checker: Is There Finance on a Car?
Updated October 2026 · Independent information, not legal advice
A reading is only as trustworthy as the story around it. This is why a good mileage history check looks at the pattern across several years rather than a single number, and why it sits alongside the V5C, the paperwork and a sensible inspection of the car itself.
How Can You Check The Mileage Of A Car?
The quickest way to check car mileage is to enter the registration into the free number plate check and read the odometer figure recorded at each MOT. Each test lists the date, the result and the reading taken by the tester.
What you will see
The free lookup shows the recorded reading for every MOT test the vehicle has had since the records began, alongside pass or fail results and advisories. It does not show the live figure on the dashboard, because nobody reports that to the authorities between tests.
What you will not see
A lookup by registration does not show service history, outstanding finance, stolen status or the number of previous keepers. Those come from other sources, covered later.
Where Do MOT Mileage Readings Come From?
The tester records the odometer reading at the start of each MOT and enters it into the DVSA system along with the test result. That entry becomes part of the permanent mileage history for that registration.
- Tester entry: the figure is typed in by the test station, so occasional typing slips do occur.
- Official record: once submitted, it appears in the public MOT history for the vehicle.
- Annual snapshot: you get one reading roughly every twelve months once a car is old enough to need an MOT.
Why one reading a year matters
A yearly snapshot is enough to show a trend. A car doing very different distances between tests, or a reading that falls, stands out immediately.
How Many Miles Has My Car Done?
If you want to know how many miles has my car done, the most recent MOT reading is the best independent figure available, and the dashboard is the live one. Compare the two: the dashboard should be at or above the last test reading, never below it.
Working out miles since the last test
Subtract the last MOT reading from the dashboard figure and look at the date gap. A sensible result matches how the car is normally used.
Checking the mileage on my car when I am the owner
Owners use the same record to confirm their own mileage on my car has been logged correctly. A wrong entry can be queried with the test station and DVSA.
How To Read An MOT Mileage History
Reading the history is about patterns, not single figures. Line the readings up in date order and ask whether each year's gain is believable.
A step-by-step method
- List every reading and date from the first test onward.
- Work out the gain between each pair of tests.
- Compare the gains with each other and with the type of car.
- Flag any year where the figure drops, stalls or jumps oddly.
A healthy history
Gains of similar size from year to year, with a small variation for holidays or a change of job, look natural.
A suspicious history
A sudden fall, a long stall, or a leap far outside the usual pattern deserves questions before you buy.
Table Of Typical Mileage Patterns
| Pattern | What you see | Possible explanation |
|---|---|---|
| Steady rise | Similar gain each year | Normal use by a regular driver |
| Reading falls | A later figure lower than an earlier one | Typing error, unit mix-up or a tampered odometer |
| Flat years | Almost no change between tests | Car laid up, SORN, or reading not updated |
| Big jump | One year far above the rest | Change of job, long trips or a mistake |
| Missing test | Gap in the record | Exemption, test abroad or lapsed MOT |
Reading the patterns carefully
Treat the table as a prompt for questions, not a verdict. None of these patterns proves anything by itself.
What Does It Mean When Mileage Goes Down?
When mileage goes down between two MOTs, there are only a few explanations: a typing error by the tester, a unit mix-up between miles and kilometres, a replaced instrument cluster, or deliberate odometer tampering known as clocking. The first three are innocent and checkable; the last is illegal.
Innocent explanations
- Data entry slip: a missing or extra digit at the test station.
- Replacement dash: a new cluster fitted with the old figure not transferred.
- Imported vehicle: a car originally reading in kilometres.
When to walk away
If the seller cannot explain a fall with paperwork such as invoices or an earlier garage record, treat it as a warning and consider another car.
What Is Clocking And Why Is It A Problem?
Clocking means winding back an odometer to make a car look as though it has covered fewer miles, and it can mislead a buyer into paying more than the car is worth. Altering an odometer to deceive is illegal, and a seller who does it may face prosecution.
Digital dashboards have not removed the risk, because tampering tools exist for them as well. That is why independent records, such as the DVSA test readings, carry weight.
Warning signs on the car
- Worn pedals and steering wheel: wear far beyond the displayed figure.
- Tired driver's seat: sagging bolsters and shiny trim.
- Door shut gaps and stone chips: heavy front-end chipping on a "low mileage" car.
Is A Free Mileage Check Enough?
A free mileage check is a strong first filter but not the whole job. It tells you what the MOT system recorded; it does not tell you about hidden finance, a stolen status, a write-off category or the car's service record.
If the car passes the free test, a commercial vehicle history check can add finance, police and insurer data. The free versus paid vehicle checks comparison explains which gaps each fills.
A sensible order of checks
- Free lookup of MOT mileage history.
- Paperwork and V5C inspection.
- Commercial history check if you are serious.
- Physical inspection or independent mechanic.
Vehicle Mileage Check Free: What The DVSA Data Covers
A vehicle mileage check free of charge draws on the DVSA MOT history, which covers Great Britain. Cars first tested in Northern Ireland are covered by the Driver and Vehicle Agency (DVA), a separate body, so the same readings may not appear there; see MOT in Northern Ireland.
Which regions are covered
- Great Britain tests: included.
- Northern Ireland tests: run by the DVA, recorded separately.
- Republic of Ireland: not on UK systems at all.
Car Mileage Check Free On A Car Under Three Years Old
Most cars have no MOT until the third anniversary of first registration, so a car mileage check free online will often show no readings at all for a nearly new vehicle. That is normal and not a red flag.
What to use instead
- Service stamps and invoices: dealer servicing usually records mileage.
- Delivery mileage on the V5C or sales paperwork: where the seller has it.
- Manufacturer records: a franchised dealer can sometimes confirm.
Mileage Checker UK: What Counts As Evidence?
A mileage checker UK buyers use should be treated as one piece of evidence among several. The strongest evidence is consistent across sources.
Sources that support each other
- MOT readings: independent and dated.
- Service history: garage stamps and invoices with mileages.
- Previous adverts and photos: older listing pictures sometimes show the dash.
- Tyre and wear condition: must match the story.
When two sources disagree, ask the seller to explain before handing over any money.
Does Service History Help Verify Mileage?
Yes. A full car service history with dated invoices and mileages gives a second independent timeline to compare with the MOT readings. A service at a certain mileage in a certain month should sit sensibly between the nearest MOT readings.
Digital service records
Some manufacturers keep electronic service records that a franchised dealer can read by VIN. Ask the dealer whether this is available for the make.
Paper service books
Stamps can be forged, so check that the garage exists, the dates make sense and the handwriting and ink are not suspiciously uniform.
How The V5C And Logbook Fit In
The V5C, often still called the logbook, records the registered keeper, not the legal owner, and it does not record mileage. It still helps, because the issue date and the keeper details tell you how recently the vehicle changed hands. Read about the V5C issue date and the vehicle registration document information before relying on it.
- Recent V5C issue date: may mean a recent change of keeper.
- Mismatched details: colour, engine size or VIN differences need explaining.
- No V5C at all: a serious problem; do not buy.
Why Mileage Affects Value
Mileage is one of the biggest factors in what a used car is worth, alongside age, condition and service record. Even a modest wind-back can change the asking price noticeably, which is why dishonest sellers target it.
Mileage versus condition
A car with higher miles and a full, documented history can be a better buy than a low-mileage car with no proof. Wear and care matter as much as the number.
Mileage and finance
Some finance agreements set mileage limits, which is one reason to also check for outstanding finance on any car you are considering.
What Counts As A Typical Mileage?
There is no official "right" mileage for a given age, because use varies enormously. A rural commuter, a salesperson and a weekend driver will differ hugely.
Use patterns, not averages
- Company cars and taxis: tend to show high annual gains.
- Second cars: often lower than average.
- Diesels: frequently bought by higher-mileage drivers.
- Electric vehicles: can show unusual patterns because of charging habits and short-trip use.
Judge the pattern against the car's likely use rather than a national average, and never rely on a quoted statistic.
Imported Vehicles And Mileage
An imported vehicle often arrives with an odometer reading in kilometres, and its pre-import history is not on the DVSA system. Mileage can look low after import because the car's earlier years are invisible.
What to ask for
- Foreign registration documents: showing earlier mileage.
- Service records from the origin country.
- The date the vehicle was first registered in the UK.
The vehicle's vehicle provenance before import is the weak spot, so ask for as much documentation as the seller can supply.
Motorbikes, Vans And Classics
Motorbikes, vans and classics follow the same MOT rules but the quirks differ. Read more on motorbike HPI checks for bike-specific concerns.
Differences by vehicle type
- Motorbikes: readings are recorded but the pattern is more seasonal.
- Vans: high mileage is normal, so look for consistency rather than low figures.
- Classic and historic vehicles: many are exempt from the MOT, so there may be few or no readings.
- Mopeds: small displays and cable-driven clocks are easy to misread.
What If The Odometer Has Been Replaced?
A replaced or repaired instrument cluster is legitimate in many cases, but the mileage should be transferred or documented. Ask for the garage invoice that shows the work and the reading at the time.
What a legitimate replacement looks like
The invoice names the garage, the date, the old reading and the new one. The next MOT then continues from the correct figure.
What should worry you
A seller with no paperwork, a cluster that does not match the rest of the interior, or a sudden drop in the MOT record all deserve caution.
Common Mileage Myths
Several myths circulate about mileage and they lead buyers astray.
Four myths that mislead buyers
- "Digital odometers cannot be altered": they can.
- "Low mileage always means a better car": not if it was short-tripped, neglected or clocked.
- "The MOT guarantees the mileage is right": it only records what the tester read.
- "Mileage on the V5C": the V5C does not carry it.
A Buyer's Mileage Checklist
Before paying, run through a short list that combines the record, the paperwork and the car itself.
Steps before you pay
- Enter the registration into the free lookup and read every MOT reading.
- Calculate the gain each year.
- Match the last reading to the dashboard figure.
- Ask for service invoices with dates and mileages.
- Check pedal, seat and steering wheel wear.
- Run a commercial check for finance, stolen and write-off data.
Beyond Mileage: Other History Checks
Mileage is one thread in a car's story. A rounded view adds the following:
Other records to combine
- Outstanding finance: held by finance companies and shown on commercial checks.
- Stolen vehicle markers: held by the police via the Police National Computer and passed to commercial checkers.
- Write-off category: recorded by insurers on the MIAFTR database.
- Scrapped vehicle status: recorded by the DVLA and authorised treatment facilities.
- Insurance: shown on the Motor Insurance Database and askMID.
The rapid car check idea is to combine as many of these quickly as possible before a viewing.
HPI-Style Checks And Mileage
Commercial services often described as HPI style checks add a mileage flag by comparing registered readings from other sources, such as previous keepers' records and dealer data. The service varies by provider, and none should be treated as infallible.
How to use one sensibly
Use the report to cross-check what the MOT shows, never as a replacement for your own inspection. The cost is set by the provider and should be weighed against the price of the car.
What To Do If You Find A Mileage Anomaly
If the history shows a fall or a suspicious gap, do not accuse; ask. Many anomalies have simple explanations.
Steps if the record looks wrong
- Ask the seller to explain the specific readings.
- Request invoices or garage records for the period.
- Contact the testing station if you suspect an entry error.
- Walk away if the answers do not hold up.
If you have already bought
If you discover tampering after purchase, you may have consumer rights against the seller. Contact Trading Standards or Citizens Advice for guidance on your position.
Can A Wrong MOT Mileage Be Corrected?
If the recorded reading is a genuine mistake, the test station that entered it can usually raise a correction with the DVSA. Owners should keep evidence, such as a photo of the dashboard from that day, because a correction depends on proof.
Who to contact
- The garage or test centre that carried out the test.
- DVSA through GOV.UK for the official correction route.
How To Check Car Miles Quickly
To check car miles in under a minute, enter the registration, scroll to the test list and note the last two readings and their dates. If the gap between them is believable and the dashboard sits above the latest figure, the quick check is passed and you can move on to deeper checks.
When a quick look is not enough
If the car is expensive, has gaps in its tests or the seller is evasive, spend longer on the paperwork and consider a commercial check.
Mileage And Insurance
Insurers often ask for an estimated annual mileage, and an honest figure keeps a policy valid. The MOT record can help you estimate what you actually drive.
Estimating annual mileage
- Under-declaring: can cause problems if you claim.
- Over-declaring: may raise the premium needlessly.
- Checking history: use past MOT gains for a realistic number.
Remember that the Motor Insurance Database shows whether a vehicle is insured, not its mileage. A quick insurance check is a separate task.
Selling A Car And Mileage Honesty
If you are the seller, an accurate mileage and a full paper trail help your sale. Describing the mileage truthfully in the advert is a legal expectation, and misrepresenting it can have serious consequences.
Building an evidence file
- Keep MOT certificates: each one carries a reading.
- Keep service invoices: a ready-made evidence file.
- Be upfront: about any odometer repair.
Mileage History On A Part-Exchange Or Trade-In
Dealers who take a trade-in usually check the MOT readings before agreeing a value, so expect questions about gaps or falls. Having your own certificates and invoices to hand speeds things up and supports the figure you declare.
Keeping your own record
A simple note of the mileage each time you refuel or service the car creates a personal timeline that backs up the official one.
Where The Official Records Live
To check car mileage history, the main free source is the odometer reading recorded at each MOT test, which the DVSA publishes. A mileage checker car lookup is only as good as those readings, so a vehicle check mileage result should be read alongside service invoices and the condition of the car.
The official mileage record is the MOT history held by the DVSA and published through GOV.UK. The DVLA holds the vehicle register, tax and V5C data. These are separate systems that work together.
Always confirm on GOV.UK
For the final word on how mileage is recorded, how to dispute an entry or whether a vehicle needs an MOT, check the relevant GOV.UK service, and for Northern Ireland the DVA.
Final Points Before You Buy
A mileage record gives you facts, not a guarantee. The most reliable decision combines the MOT history, documented servicing, a clean commercial check and your own eyes.
If any piece does not fit, pause. A genuine seller will understand that a careful buyer is a good buyer, and another suitable car is usually available.
Frequently Asked Questions
How can you check the mileage of a car for free?
Enter the registration into a free lookup built on the DVSA MOT history. It lists the odometer reading recorded at every MOT test in Great Britain, with the date and result. Compare the readings in date order and check the latest against the dashboard. The free route does not show service history, finance or stolen status, so combine it with paperwork and, for a serious purchase, a commercial history check.
Is a free mileage check accurate?
It accurately reflects what the test station recorded at each MOT, but it cannot prove the figure was right. Testers can mistype, and a tampered odometer can show a false reading that is then recorded faithfully. Treat the record as strong supporting evidence, then compare it with service invoices, wear on the car and, ideally, a commercial history check.
Can mileage go down on an MOT history?
It can, but it needs an explanation. Common innocent causes are a data entry slip, a replaced dashboard, or a unit mix-up on an imported vehicle. The worrying cause is clocking, which is illegal. Ask the seller for garage invoices covering the period, and if no convincing explanation emerges, consider walking away from the car.
Does the V5C show mileage?
No. The V5C, or logbook, records the registered keeper, vehicle details and the issue date, but not the odometer reading. Mileage evidence comes from MOT test records, service invoices and dealer or manufacturer data. The V5C is still useful for checking the car matches its description and for seeing how recently it changed keeper.
How many miles has my car done?
The best independent figure is the most recent MOT reading, which you can see through a free lookup by registration. For the live figure, read the dashboard. The dashboard should be at or above the last test reading. Subtracting one from the other, and looking at the dates, shows what you have driven since the test.
Why does a new car show no mileage history?
A car normally does not need an MOT until the third anniversary of first registration, so a free mileage history check will usually show nothing for a young vehicle. That is expected. Use dealer service records, delivery paperwork or the manufacturer's records to build the picture until the first test is recorded.
Can a garage correct a wrong MOT mileage?
In many cases the test station that entered the reading can raise a correction with the DVSA if there was a genuine mistake. Evidence helps, for example a dated photo of the dashboard. The exact route is on GOV.UK, so check there before contacting anyone, and keep copies of any correspondence.
What is clocking?
Clocking is winding back or altering a vehicle's odometer so it shows fewer miles than the car has covered. It is used to raise the selling price and is illegal where done to deceive. Signs include wear that does not match the displayed figure and MOT readings that fall or stall. Independent records and a careful inspection help expose it.
Does a mileage check show finance or stolen status?
No. The free MOT-based record covers mileage, test results and tax status. Outstanding finance, stolen markers and write-off data sit with finance companies, the police and insurers, and appear on commercial history checks. For a used car, run both: the free mileage history first, then a commercial check before you pay.
Are mileage readings recorded in miles or kilometres?
Readings in Great Britain are normally recorded in miles, but imported cars may show kilometres on the dashboard and testers can record the unit. A sudden apparent fall that matches a kilometres-to-miles difference is a classic cause of confusion. Ask the seller about the car's import history and look at the original foreign documents.
Is mileage recorded for motorbikes and vans?
Yes. Motorbikes and vans have MOT readings recorded like cars once they are old enough to need a test. Vans often show high annual gains, and bikes may show seasonal patterns. Judge each against its likely use. Exempt historic vehicles may have few readings, so look for other evidence such as invoices.
Can I check the mileage of a car in Northern Ireland?
Northern Ireland vehicle tests are run by the Driver and Vehicle Agency (DVA), not the DVSA, so the free Great Britain lookup may not show them. Vehicle registration and tax still sit with the DVLA. For a Northern Ireland car, ask the seller for test certificates and check the DVA's services directly.
What should I do if I suspect the mileage is wrong?
Ask the seller to explain the specific readings and to provide invoices or garage records. Check wear on the pedals, seat and steering wheel against the figure. If the explanation is weak, do not buy. If you have already bought, contact Trading Standards or Citizens Advice about your rights.
How do I check the mileage history of a car for free?
Enter the registration into the free lookup to see the odometer reading at each MOT test. That gives a free mileage checker car view of how the figure has risen over time. Look for readings that fall or stall, then compare them with invoices and wear. A commercial check may add other data, but the MOT readings are the free starting point.
