What does clocked mileage mean?
Clocked mileage means a car's odometer has been deliberately tampered with to display a lower mileage than the vehicle has actually travelled. This is done to misrepresent the vehicle's condition and increase its value. Clocking is illegal in the UK and creates a permanent discrepancy in the vehicle's mileage records.
Why clocked mileage matters to buyers
Value misrepresentation
Clocked mileage makes a vehicle appear to have travelled fewer miles than it actually has, leading to an inflated asking price. You may pay significantly more than the vehicle is worth based on its true mileage.
Hidden wear and tear
A clocked vehicle will have more wear and tear than indicated by the displayed mileage. This can affect reliability, maintenance costs, and the need for repairs sooner than expected based on the false mileage reading.
Legal implications
Odometer tampering is illegal in the UK. If you purchase a clocked vehicle, you may have legal recourse against the seller, but proving clocking can be difficult without proper documentation and evidence.
Resale value
If you later discover the vehicle was clocked when selling it, the clocking will affect the resale value and may deter potential buyers. The mileage discrepancy remains on the vehicle's history permanently.
What clocked mileage indicates
Clocked mileage occurs when someone deliberately reduces the displayed mileage on a vehicle's odometer to make it appear to have travelled fewer miles. This is typically done by physically altering the odometer mechanism or using electronic tools to reset digital odometers.
Clocking is done to increase a vehicle's apparent value by making it seem less used than it actually is. However, the vehicle's true mileage is recorded in official records such as MOT tests, which cannot be altered. Comparing these records reveals the discrepancy.
Clocked mileage creates a permanent discrepancy in the vehicle's history. Official MOT records show the true mileage progression, and any reduction in displayed mileage compared to previous records indicates potential clocking. This information is accessible through vehicle history checks.
What to check before buying a potentially clocked vehicle
- Run a vehicle history check to review the complete mileage history
- Compare the current odometer reading with MOT test records
- Request service records to verify mileage progression
- Check for signs of odometer tampering, such as loose instrument clusters or mismatched screws
- Verify the seller's explanation for any mileage discrepancies
- Have an independent mechanic inspect the vehicle for wear consistent with the displayed mileage
- Consider walking away if clocking is suspected or cannot be ruled out
- Be cautious of vehicles with unusually low mileage for their age
How a vehicle history check helps
A vehicle history check provides official records from UK databases, including MOT test history with recorded mileage at each test. This helps buyers identify clocked mileage by comparing the displayed mileage with official records and identifying any reductions or inconsistencies.
Sellers may not disclose clocked mileage, or may be unaware of it if they purchased the vehicle already clocked. A vehicle history check provides independent verification from official sources, automatically flagging potential clocking and helping buyers avoid purchasing vehicles with tampered mileage.
What a Carpeep vehicle history check can show
- Mileage inconsistencies and potential odometer rollbacks, automatically flagged
- MOT history timeline, including all test dates, pass/fail results, advisories, and recorded mileage at each test
- Write-off category (Cat S, Cat N, Cat A, Cat B, Cat C, Cat D) and date of write-off
- Theft and recovery status, including whether the vehicle has been reported stolen
- Outstanding finance agreements, including provider name, agreement type, and start date
- Keeper changes and number of previous owners
- Registration plate changes and vehicle identity verification
Frequently asked questions
Is clocked mileage illegal?
Yes. Odometer rollback, or clocking, is illegal in the UK. Deliberately reducing or altering a vehicle's displayed mileage to misrepresent its condition or value is a criminal offence. Clocking creates mileage discrepancies and inconsistent mileage records. If you discover clocking, you may have legal recourse against the seller.
How can I tell if a car has been clocked?
You can identify clocked mileage by running a vehicle history check that includes MOT history. Compare the recorded mileage at each MOT test - if the mileage decreases between tests, this indicates clocking. Physical signs may include loose instrument clusters or signs of tampering.
Does clocked mileage affect value?
Yes. Clocked mileage significantly affects vehicle value. If the true mileage is higher than displayed, the vehicle is worth less than its asking price. Clocking can reduce a vehicle's value substantially, and the discrepancy remains on the vehicle's history permanently.
What should I do if I discover clocked mileage?
If you discover clocked mileage, you should not complete the purchase. If you have already purchased the vehicle, you may have legal recourse against the seller. Report suspected clocking to trading standards and consider seeking legal advice.
Can clocked mileage be fixed?
The displayed mileage can potentially be corrected, but the clocking record remains in the vehicle's history permanently. Official MOT records show the true mileage progression, and any clocking will always be visible in vehicle history checks.
How common is clocked mileage?
Clocked mileage is a known problem in the used car market, though exact prevalence is difficult to determine. Running a vehicle history check with MOT mileage records is the most reliable way to identify potential clocking before purchasing a vehicle.
