Why Should You Check Car Mileage Before Buying?
Checking a car’s mileage before buying helps you confirm that the recorded mileage matches the vehicle’s history. A genuine mileage check shows the readings recorded during MOT tests, helping you identify unusual changes and make a more informed buying decision. The REGUP mileage check uses available MOT mileage records to create a clear timeline, so you can see whether the mileage pattern looks consistent before purchasing a used car.
The Mileage Timeline
Every MOT test records the mileage at the time of the test. From the car third birthday, a new reading is added each year. The REGUP mileage check lines these readings up in order and flags any that do not behave the way real mileage should. A genuine car shows a steady upward climb. A clocked car shows drops, jumps or flat periods that cannot be explained by normal use.
Reading The Results
The check returns the mileage at each recorded MOT date. Read it from earliest to latest and look for three things.
Pattern | What it means | Risk level |
|---|---|---|
Steady rise, consistent gaps | Normal use, roughly 5,000 to 10,000 miles per year | Low |
Gradual rise, then a sudden drop | Possible clocking — the odometer has been wound back | High |
Large unexplained jump between tests | Could be genuine high use, or a replacement cluster with higher reading | Medium — ask for evidence |
Flat or barely rising over several years | Very low use, or the car was standing — check for SORN periods | Medium |
No readings (car under 3 years) | No MOT yet, so no recorded mileage timeline | Check service records instead |
Clocking: The Risk This Check Catches
Mileage clocking is winding back the odometer to make a car look like it has done fewer miles than it really has. Lower mileage means a higher price, so the seller profits from the difference. On modern cars, digital odometers can be altered in minutes with cheap plug-in tools. There is no physical trace on the dashboard. The only reliable evidence is in the records, and the mileage check is what surfaces it. The RAC estimates that hundreds of thousands of clocked cars are on UK roads at any time.
Expected Mileage By Age
Use these benchmarks to judge whether a reading looks right for the car age. The UK average is roughly 7,000 to 8,000 miles per year, with diesels typically higher and city cars lower.

A reading in the "low" column is not automatically a bargain. If it looks too low for the car age and condition, it may have been clocked. Treat a suspiciously low reading the same way you would a suspiciously high one: check the records and ask questions.
Factors That Shift Expected Mileage
Fuel type: Diesels typically cover more miles per year because they suit motorway use. Petrol and electric cars tend to sit at or below the average.
Use type: A motorway commuter car covers more miles but under gentler conditions than a town car doing the same distance in stop-start traffic.
Owner type: Company cars and fleet vehicles often cover 15,000 to 25,000 miles per year. A car that moved from fleet to private use may show a sharp drop in annual mileage at the keeper change.
Location: Rural owners typically cover more miles than urban owners. A car registered in central London may show very low annual mileage.
Vehicle class: Vans and commercial vehicles run higher mileage than cars on average. A van with 120,000 miles at eight years is normal; a city car at the same l
Mileage And Vehicle Value
Mileage is one of the biggest single factors in a used car price after age and condition. Two identical cars can differ by hundreds or thousands of pounds on mileage alone. Cars that cross round numbers such as 60,000 or 100,000 often step down in value. This is exactly why clocking exists: removing 30,000 miles from a reading can add a thousand pounds or more to the asking price. Confirming the mileage is genuine with this check protects both the price you pay and the price you recover when you sell.
Run a valuation check alongside to see whether the asking price matches the genuine mileage.
Mileage And Vehicle Wear
Higher mileage means more wear on every moving part. Cambelts, clutches, brake components, suspension bushes and wheel bearings all have service lives measured in miles. A car showing 40,000 miles that has actually done 80,000 is halfway through the life of components the owner thinks are barely used. The next cambelt failure, clutch replacement or suspension rebuild arrives sooner than expected, and the cost falls on you. The AA used car inspection guide recommends checking the mileage record as part of every pre-purchase assessment for exactly this reason.
Combining Mileage With Other Vehicle Checks
Mileage is one layer of the vehicle history. A genuine mileage reading does not mean the car is free of finance, stolen markers or write-off history. For the fullest protection before buying, combine the mileage check with a finance check, stolen check and write-off check. The pre-purchase used car check bundles everything into a single report.
Cars Under Three Years Old
A car under three years old has not had an MOT yet, so there is no public mileage timeline. For these vehicles, rely on the service history, the dealer pre-delivery inspection and any invoices. Ask the seller to account for the mileage and keep the evidence. Once the car reaches its third year and has its first MOT, the recorded mileage enters the public record and future checks will pick it up.
Reading The Check Alongside MOT History
The mileage check and the MOT check use the same underlying DVSA data but present it differently. The mileage check focuses on the mileage readings and flags anomalies. The MOT check shows the full test result including advisories and failures. Read them together: a car that shows steady mileage and clean MOT passes tells a consistent story of regular maintenance. A car with a mileage drop at the same point as a cluster of MOT failures tells a very different story.

Mileage Check FAQs
What is a mileage check?
It reviews available mileage readings and flags possible inconsistencies or unusual patterns where data is available.
Can a mileage check find clocking?
It can help spot mileage concerns, but no online report can guarantee detection of every mileage alteration.
Why does mileage matter?
Mileage affects value, servicing, wear and resale. A suspicious mileage record can change the buying decision.
What should I do if mileage looks wrong?
Ask for service records, MOT history and invoices. Walk away if the seller cannot explain the inconsistency.
Can I check mileage by reg?
Yes. Enter the UK registration number and REGUP will prepare the mileage check flow.
Is the mileage check free?
Yes. It uses DVSA MOT data and is free by registration. No account required.
How far back does the mileage record go?
From the car third birthday (first MOT). Earlier mileage relies on service records and dealer paperwork.
Can mileage legitimately go down?
Rarely. A replaced instrument cluster can reset the reading. If mileage drops, ask for the invoice that proves the repair.
Does low mileage always mean a better car?
No. Very low mileage can mean long periods standing still, which perishes seals and tyres. It can also signal clocking.
Can I check mileage on a car under three years old?
There is no MOT record yet, so no public mileage timeline. Use the service history and dealer paperwork.
Does the check guarantee the mileage is genuine?
No check can guarantee it. The timeline shows the recorded readings and flags anomalies. Combine it with a physical inspection for the fullest confidence.
How does clocking affect value?
Removing 30,000 miles can add a thousand pounds or more to the asking price. Confirming mileage is genuine protects the price you pay and what you recover at resale.
