To check a car's mileage in the UK, look up its registration on the free GOV.UK MOT history service. Every MOT test records the odometer reading, so the list of tests gives a mileage trail from the car's first MOT, and a reading lower than an earlier one is the red flag for clocking. A car mileage check lines up those readings with other dated records and the finance, write-off and stolen checks in one report.
The GOV.UK service needs no login, no V5C and no payment, and every buyer should use it. But it is not the whole story. It only tells you what a tester recorded once a year, and only from the car's first MOT, usually at three years old.
A car under three years old has no MOT history at all. A ten-year-old car's mileage could have jumped by 40,000 miles in the eleven months since its last test and you would have no way to know from that record alone.
This guide covers every method for checking a car's genuine mileage in 2026, from what is genuinely free and what needs paying for to how to read what you find and how to physically check a car's wear against its odometer when the paperwork runs out.
Key takeaways
- The free method: GOV.UK's MOT history service (check-mot.service.gov.uk) shows mileage at every MOT since 2005, using only the registration number. It is completely free.
- The gap: Cars under three years old have no MOT history, and mileage between MOTs, up to 12 months of driving, is never recorded anywhere free.
- The paid layer: A full vehicle history check puts the MOT readings on one timeline with other dated readings, such as the mileage shown in previous adverts, and adds finance, write-off and stolen checks. No check can prove a car has not been clocked.
- Physical checks still matter: wear on the steering wheel, pedals, gearknob, driver's seat bolster and keys should roughly match the indicated mileage. A pristine interior on a "high-mileage" car, or the reverse, is a red flag no database will catch.
- Clocking itself sits in a legal grey area, but a trader selling a car with a false mileage reading breaks consumer protection law (now the Digital Markets, Competition and Consumers Act 2024), and knowingly selling one can be fraud under the Fraud Act 2006.
Before you view a car, run both checks. The free GOV.UK MOT history takes a minute and flags obvious mileage drops. A full Carhealth vehicle history check goes further, showing the mileage recorded at each MOT and in previous adverts on one timeline so you can spot a jump or a fall, alongside outstanding finance, write-off markers, stolen records and plate changes. You can check the car with just the registration.
How to check a car's mileage for free: the GOV.UK MOT history check, step by step
The official, free way to check mileage history on any UK car is the DVSA's MOT history service, accessed via gov.uk/check-mot-history, which hands you off to the checking tool itself at check-mot.service.gov.uk.
It is run by the Driver and Vehicle Standards Agency and pulls directly from the same database MOT testers write to on test day, so the mileage figures are as close to a primary source as a free UK service gets.
What you need
- The car's registration number (number plate). That is all you need.
- You do not need the V5C logbook, the owner's name, or any payment details.
- The tool works for cars, motorcycles and vans back to 2005; heavy goods vehicles, trailers, buses and coaches are covered from 2018; Northern Ireland records run from 2017.
Step-by-step
- Go to www.gov.uk/check-mot-history and click "Start now" (or go directly to check-mot.service.gov.uk).
- Type in the registration number exactly as it appears on the plate. No spaces are required; the tool strips them automatically.
- Submit the search. The results load instantly; there is no waiting period and no account to create.
- Check the summary at the top of the page: current MOT status, the expiry date, and the mileage recorded at the most recent test.
- Open the full test history. Every MOT the car has had is listed: date, result (pass, fail, or pass with advisories), the mileage recorded on that day, and the specific defects noted.
- Read down the mileage column, oldest to newest. This is the single most useful thing this free tool does for a buyer: it lets you see the car's mileage progression across its entire tested life at a glance.
- Download the certificate if you need it. Current and past MOT certificates can be downloaded as PDFs directly from the results page.
What the results actually show you
- Pass or fail result for every test since 2005 (2018 for HGVs, 2017 for Northern Ireland)
- The mileage recorded by the tester at each test
- The date of each test and when the next one is due
- Every defect: advisories (minor, monitor it), majors and dangerous faults (must be fixed)
- For vehicles tested in England, Scotland and Wales, the test location is also shown
What it will not show you
- Anything before the car's first MOT (registration date to age three)
- Mileage covered between MOT tests, the biggest blind spot, covered below
- Outstanding finance, theft markers, insurance write-off history or number plate changes
- Anything about the car if it was recently imported and has not yet had a UK-registered MOT
Why the free MOT check alone is not enough
The GOV.UK service is genuinely excellent for what it does, and every buyer should use it before viewing a car.
But it has structural gaps that a determined seller, or an honest one with a genuinely patchy history, can fall into.
1. Cars under three years old have no MOT history at all
The first MOT is due three years after a vehicle's first registration date. A nearly-new car being sold with 40,000 miles on the clock after two years of heavy motorway use has zero MOT records to check it against.
You are relying entirely on the seller's word, the service book, and, if the original supplying dealer is contactable, their records.
2. Mileage between tests is never recorded anywhere free
MOT tests happen once a year. A car could show 45,000 miles at its MOT in March and be sold in November having "only" done another 3,000 miles, or the odometer could have been wound back by 20,000 miles in the meantime and there would be no free record of it until the next MOT catches the discrepancy, by which point you already own the car.
This is the single biggest reason clocking often goes undetected until it is too late: fraudsters roll the mileage back after the last recorded test, sell quickly, and the buyer has no free way to catch it until 12 months later.
3. Private sales, imports and exports break the paper trail
- Private sales are not required to be logged anywhere beyond the V5C keeper change, so there is no independent mileage checkpoint between owners outside the annual MOT.
- Imported vehicles often arrive with no UK MOT history at all, and their overseas service or MOT-equivalent records (if any) are not linked into the DVSA database.
- Exported and re-imported cars can have gaps in their UK record for the time they spent abroad.
Northern Ireland MOT (technically the MOT test) records were only brought into the same online history service from 2017, so a car that has spent time registered in Northern Ireland before crossing to GB, or vice versa, can show a shorter online history than its true age would suggest.
Treat a thin record on an older car as a prompt to ask for paperwork, not proof of anything sinister on its own.
4. Pre-2005 cars have no digital MOT record
If a car was first registered before the DVSA's records began, its early mileage history simply is not there to check, free or otherwise.
Method-by-method comparison: what each source of mileage data actually gives you
| Method | What it shows | Cost | Where it falls short |
|---|---|---|---|
| GOV.UK MOT history (check-mot.service.gov.uk) | Mileage at every MOT since 2005 (2018 HGV, 2017 NI); pass/fail; defects; test location | Free | No record before age 3; nothing between MOTs; no finance/theft/write-off data |
| Previous adverts and auction records | The mileage shown each time the car was advertised, or on a salvage auction lot sheet | Included in some paid history checks | Only exists if the car was advertised or auctioned; adverts are the seller's own figure |
| Full paid vehicle history check (e.g. Carhealth) | MOT mileage + advert mileage + outstanding finance + stolen marker + write-off category + plate change history | Paid | Shows recorded readings but cannot prove the car has not been clocked, so pair it with a physical inspection |
| Service history / dealer invoices | Independent mileage snapshots at each service, often more frequent than annual MOTs | Free (if the seller has them) | Easily lost, easily faked with a compliant garage, no independent verification |
| Physical inspection (wear vs indicated mileage) | Real-world confirmation the car's condition matches the number on the dial | Free (your time) | Subjective; skilled fraudsters replace obviously worn parts to match a false low reading |
| DVLA vehicle enquiry service | Tax status, SORN status, MOT expiry, CO2 figures | Free | Does not show mileage or historic MOT results at all |
Beyond the MOT: the other dated readings that catch clocking
The MOT database is the backbone of any mileage history, but it is not the one place a dated reading is kept. Two other sources matter because they are tied to a specific day and a specific car:
- Salvage auction records: when a car has been through a salvage auction, the lot sheet records the mileage on the day it was sold.
- Previous adverts: every time the car was advertised for sale, the listing showed a mileage. A car advertised at 60,000 miles two years ago and 45,000 miles today needs a very good explanation; treat it as a likely clocked car unless the seller can prove otherwise.
Industry records from finance companies, insurers and dealer networks exist too, but they are mostly rounded estimates declared at a keeper change or a service, and in practice they rarely contradict a full MOT history.
Lining these readings up in date order is what matters. If any later reading is lower than an earlier one, or the figure on the dashboard today is lower than a reading from months ago, ask why before you go any further. If the readings rise steadily, that is reassuring, but it is not proof: a car clocked since its last recorded reading will still look clean.
A Carhealth mileage check shows the mileage recorded at each DVSA MOT test and in previous adverts on one timeline, alongside outstanding finance, stolen vehicle records, insurance write-off category and number plate change history, so you can spot a jump or a fall without piecing it together yourself. It does not verify or certify the mileage, so pair it with the physical checks below.
How to check mileage with just a registration number
Every method that matters for a UK buyer in 2026 starts with the same single piece of information: the registration number.
You do not need the V5C, the chassis number, or the owner's permission to run either the free or the paid checks described above.
- Free first pass: Enter the registration into the GOV.UK MOT history service and read the mileage column across every test.
- Paid full pass: Enter the same registration into a paid history check. A good one lines up the MOT readings with other dated readings such as previous adverts, and adds finance, theft and write-off status.
- Cross-check against the advert and the seller's word: The mileage the seller states, the latest MOT reading, and the mileage on the dashboard (in the advert photos, then at the viewing) should line up, allowing for miles driven since that MOT. Any inconsistency between these three is worth asking about before you even book a viewing. The V5C logbook does not record mileage, so it cannot help here.
A "mileage checker" in the sense most people search for, a single tool where you type in a reg plate and get a definitive mileage history, does not exist as one free government service.
It is really two layers: the free DVSA MOT record, and a paid check that adds other dated readings and the finance, theft and write-off checks the free tool leaves out.
Reading MOT mileage records: what normal, gaps and anomalies look like
Once you have the mileage column from the MOT history, the analysis is straightforward. Many UK cars now cover well under 10,000 miles a year, so a figure in that region is a sensible yardstick.
Use varies a lot: diesel cars have traditionally been bought by higher-mileage motorway drivers, so a diesel with higher annual miles is not unusual in itself.
What normal progression looks like:
| MOT test year | Mileage | Year-on-year change |
|---|---|---|
| 2021 | 18,400 | First reading |
| 2022 | 25,900 | +7,500 |
| 2023 | 32,800 | +6,900 |
| 2024 | 40,100 | +7,300 |
| 2025 | 46,700 | +6,600 |
That is a car doing broadly average miles with normal year-to-year variation. Nothing to worry about.
What to treat as a red flag:
- A mileage drop between two tests, the clearest, hardest-to-explain sign of clocking. There is essentially no legitimate reason for a car's recorded mileage to fall.
- Implausibly low year-on-year mileage for a car's age and type: a five-year-old car showing only 8,000 total miles is possible (a genuine low-mileage second car) but should be treated as unusual and verified against service history and physical wear, not taken at face value.
- A long gap with almost no mileage increase, e.g. two years passing between tests with only 500 miles added. This can be a legitimate SORN period, but ask for evidence (the SORN certificate, insurance documents showing the car was declared off-road) rather than accepting it on trust.
A worked example of what a drop actually looks like on the page:
| MOT test year | Mileage | Year-on-year change | Verdict |
|---|---|---|---|
| 2019 | 61,200 | First reading | Baseline |
| 2020 | 68,900 | +7,700 | Normal |
| 2021 | 41,300 | −27,600 | Clocked, stop and investigate |
| 2022 | 44,800 | +3,500 | Still below the 2020 reading |
A car in this state should never reach a viewing.
If you spot a table like this on any registration you're considering, walk away. The 2022 mileage is not the car's real mileage, and neither is whatever figure the seller quotes you today.

How to spot a clocked car by physical inspection
No database, free or paid, catches every clocked car. Mileage altered in the days or weeks before a sale, after the last MOT and after the last advert, will not show up anywhere.
This is where a physical inspection against the indicated mileage earns its place in your checklist.
The principle is simple: wear is honest even when a digital display is not. A car's touchpoints, the parts a driver's body contacts thousands of times a week, wear at a fairly predictable rate.
If the number on the dial does not match what your eyes and hands are telling you, trust the wear.
| Touchpoint | Light wear expected up to ~30,000 miles | Moderate wear expected 60,000 to 90,000 miles | Heavy wear expected 100,000+ miles | Red flag |
|---|---|---|---|---|
| Steering wheel | Rim feels crisp, leather/plastic grain intact | Slight shine and smoothing at the 9 and 3 o'clock grip points | Noticeable shine, softened or worn-through leather, logo badge worn flat | A glass-smooth, heavily shone wheel on a car claiming under 30,000 miles |
| Pedal rubbers | Tread pattern crisp and fully defined | Tread visibly flattened in the main contact area, edges rounding | Rubber worn through to the metal backing plate, especially on the brake and accelerator | Bare metal showing through on a "low-mileage" car, or pristine tread on a claimed 100,000-miler |
| Gearknob (manual) | Stitching and texture sharp, no shine | Visible polish/shine on the grip face, some stitching wear | Leather worn smooth and shiny, badge lettering faded or worn away | A mirror-shine gearknob paired with a low indicated mileage |
| Driver's seat bolster | Fabric/leather grain intact, no compression marks | Slight flattening and colour change on the outer (side) bolster from repeated entry/exit | Cracking, splitting or through-wear on the bolster edge, seams stretched | Heavily worn bolster on a car indicating under 40,000 miles |
| Keys and key fob | Buttons crisp, logo/lettering sharp, minimal scuffing | Some scuffing on edges, button lettering starting to fade | Rounded edges, faded or missing button symbols, scratched fob face | A brand-new-looking single key on a car claiming ten years and six figures of mileage, so ask where the spare and the service history went |
| Tyres | Even wear consistent with car's age and tyre brand | Tread depth roughly proportionate to age; matched brands front-to-rear if never replaced | Multiple mismatched tyre brands/ages (expected replacements over high mileage) | All four original tyres, still with high tread, on a car claiming very high mileage |
| Service book / stamps | Stamps at intervals consistent with manufacturer schedule and low usage | Regular stamps roughly matching mileage-based service intervals | Multiple services, cambelt/timing chain work logged where due | Service book with no stamps, missing pages, or intervals that don't add up against the claimed mileage |
None of these are conclusive on their own: a genuinely low-mileage car driven mostly by an anxious motorway commuter can still show a shiny steering wheel, and a carefully detailed high-mileage car can look better than its number suggests.
Use the table as a sense check, not a verdict: if two or three touchpoints disagree with the odometer in the same direction, that is worth walking away from or demanding an explanation for.
What to do if you suspect a car has been clocked before you buy
- Do not pay a deposit or hand over money. Once cash changes hands, your position weakens considerably.
- Re-run the free MOT history check on the spot using your phone, in front of the seller if it feels appropriate; a genuine seller has nothing to hide from this.
- Ask directly for the service history and V5C, and check the mileage recorded in the service book against both the MOT figures and the current odometer reading.
- Get a full paid history check before committing, so readings from previous adverts can be lined up against the MOT record and the dashboard.
- Ask who owned it before and why. A high number of keepers in a short period, or an unexplained gap in ownership, often accompanies mileage fraud.
- Walk away if the numbers don't add up. There is no negotiation that makes a clocked car a good deal. You are not just losing money on the price, you are buying a car with genuinely unknown wear on brakes, suspension, cambelt and engine internals.
- Report it. Suspected clocking can be reported to Trading Standards via Citizens Advice, even if you don't go ahead with the purchase; it may protect the next buyer.
Your legal position if you've already bought a clocked car
Altering an odometer is not, by itself, a specific standalone criminal offence in the UK, but selling a car with a mileage you know to be false is.
Depending on the circumstances, this can fall under:
- The Digital Markets, Competition and Consumers Act 2024 (Part 4, Chapter 1), which replaced the Consumer Protection from Unfair Trading Regulations 2008 on 6 April 2025 and bans traders from giving false or misleading information about a product's main characteristics, including mileage.
- The Fraud Act 2006, where clocking with intent to sell at an inflated price can constitute fraud by false representation, carrying penalties of up to ten years' imprisonment.
- The Consumer Rights Act 2015, if you bought from a trader (not a genuine private seller): goods must be "as described," and a car sold with a false mileage clearly is not. This can support a claim for a refund, repair, or price reduction.
- The Misrepresentation Act 1967, which can apply even in some private sales if the seller made a false statement of fact about the mileage that induced you to buy.
Practically, if you believe you've bought a clocked car:
- Gather your evidence first: the free MOT history printout, the original advert (screenshot it if it's still live), any messages with the seller, and any earlier advert or record showing a higher mileage.
- Contact Citizens Advice for guidance on your consumer rights; they can direct genuine cases to Trading Standards for investigation.
- If you bought from a dealer, raise it with them directly first and in writing, referencing the Consumer Rights Act 2015.
- For private sales, small claims court is a realistic route for claims typically under £10,000, on the basis of misrepresentation.
- Report it to Trading Standards (through Citizens Advice) regardless of whether you pursue your own claim. Clocking is a pattern crime, and one report can help stop the same seller doing it again.
This is a summary of your options, not legal advice for your specific situation. For a full walkthrough of your rights and the reporting process, see our guide on spotting and reporting mileage fraud.
The bottom line
Checking a car's mileage in the UK starts free and takes a minute: the GOV.UK MOT history service, registration number only, no account needed. Every buyer should do this before booking a viewing, full stop.
But it is a snapshot taken once a year, starting only from a car's third birthday: it cannot see mileage covered since the last test, and it says nothing about finance, theft or write-off history.
A paid vehicle history check narrows those gaps by lining up the MOT data with other dated readings such as previous adverts, and adds the checks that protect your money: finance, write-off and stolen records.
Pair either with a proper physical inspection of the steering wheel, pedals, gearknob, seat bolster and keys, and you have covered every angle a private buyer realistically can.
Ready to check a specific car? Run a full Carhealth history check: MOT history, recorded mileage from MOTs and adverts, outstanding finance, stolen markers, write-off category and plate changes, all from a registration number, with instant results. It tells you what the free lookup can't.

Frequently asked questions
Can I check a car's mileage for free?
Yes. The GOV.UK MOT history service (accessed via gov.uk/check-mot-history) shows the mileage recorded at every MOT test since 2005, free of charge, using only the registration number.
It won't show mileage for cars under three years old or anything that happened between MOT tests, but it is a genuinely free and official first check every buyer should run.
How do I check mileage with a registration number?
Enter the registration into the GOV.UK MOT history service for a free view of mileage at every MOT test. For more context, use a paid vehicle history check, which lines up those readings with other dated records such as previous adverts and only needs the registration number to run. For a car too young for an MOT, the service book and a physical inspection matter most.
Is clocking illegal in the UK?
Altering an odometer isn't a specific standalone crime in itself, but a trader selling a car with a false mileage breaks the Digital Markets, Competition and Consumers Act 2024 (which replaced the Consumer Protection from Unfair Trading Regulations 2008 in April 2025), and knowingly doing so can amount to fraud under the Fraud Act 2006, with penalties of up to ten years in prison.
If you bought from a trader, the Consumer Rights Act 2015 also gives you grounds to demand a refund or repair.
Does the MOT history show a car's full mileage history?
No. Only what was recorded at each MOT test, and only from age three onwards. Mileage covered between tests, and anything before the first MOT, isn't captured anywhere in the free record.
A paid check can add other dated readings, such as the mileage shown in previous adverts, which may fill some of these gaps. The service book is the other main source.
What is a mileage checker and how accurate is it?
There's no single official "mileage checker" tool separate from the services above. In practice it means either the free GOV.UK MOT history lookup, or a paid check that lines up that MOT data with other dated readings.
Accuracy depends entirely on how many independent mileage readings exist for that specific car; a car with a thin paper trail (private sales only, few services) will show fewer data points to check against than one serviced at franchised dealers throughout its life.
Is 70,000 miles a lot for a used car?
It depends entirely on the car's age. Many UK cars cover well under 10,000 miles a year, so 70,000 miles on a nine-to-ten-year-old car is broadly typical, not high.
The same 70,000 miles on a three-year-old car would be well above average and worth checking service history for: heavier motorway use isn't necessarily a problem if it's been well maintained, but it changes what you should budget for tyres, brakes and timing components sooner rather than later.
What if there's no MOT history for the car I'm checking?
The most common reason is that the car is under three years old and hasn't needed its first MOT yet. Other reasons include a recent import that hasn't built up UK MOT records, or a registration change that has broken the link to older records.
Ask for proof of age (the V5C first registration date), any overseas service records for imports, and treat the mileage claim with extra caution since there's no independent free record to check it against yet.
What should I do if I've already bought a car that turns out to be clocked?
Gather evidence (MOT history printout, the original advert, any messages with the seller, and any earlier record showing a higher mileage), then contact Citizens Advice for guidance on your consumer rights.
If you bought from a dealer, the Consumer Rights Act 2015 gives you a claim for refund or repair; for private sales, misrepresentation and small claims court are the usual routes. Report it to Trading Standards regardless, to help stop the same seller doing it again.
