Mileage Fraud Explained: How to Detect Clocked Cars in the UK

Summary

• Major Problem: Around 2.3 million cars on UK roads have clocked odometers. That's 1 in 16 used cars.
• Check MOT History: The easiest way to spot clocking is comparing MOT mileage readings. Use our free MOT checker.
• Trust Your Eyes: Wear patterns on pedals, seats, and steering wheel should match the claimed mileage.

Mileage fraud—also called "clocking"—is when sellers wind back a car's odometer to show fewer miles. It makes cars appear less used and more valuable.

The practice is illegal but disturbingly common. Here's how to protect yourself.

What Is Mileage Fraud?

Mileage fraud (clocking) is the illegal practice of altering a vehicle's odometer to display a lower mileage than the car has actually covered.

Why Do Criminals Do It?

• Higher sale price: Lower mileage = higher value
• Faster sale: Low-mileage cars sell quicker
• Hide wear: High-mileage cars need more maintenance
• Profit margin: Can add £1,000s to a car's value

How Common Is It?

According to various industry studies:

• Around 2.3 million clocked cars are on UK roads
• That's approximately 1 in 16 used cars
• Average victim loses £2,000-£5,000 in value
• Total cost to UK consumers: over £800 million per year

Clocking is a criminal offence under the Consumer Protection from Unfair Trading Regulations 2008.

How Criminals Clock Cars

Modern digital odometers can be altered using specialist equipment:

Digital Clocking

• OBD (On-Board Diagnostics) tools connect to the car's computer
• Software reprograms the displayed mileage
• Takes just minutes with the right equipment
• Leaves no obvious physical evidence

Older Mechanical Odometers

• Dashboard removed and odometer wound back manually
• Sometimes replaced with lower-mileage cluster
• May leave physical evidence (scratches, misaligned numbers)

Where Clocking Happens

• Before auction (to increase sale price)
• When imported (foreign mileage in km converted incorrectly)
• By unscrupulous dealers
• By private sellers hiding wear
• Before lease return (to avoid excess mileage charges)

Warning Signs of a Clocked Car

Look for these red flags when inspecting a used car:

1. MOT Mileage Discrepancies

This is the most reliable check. Every MOT records the odometer reading.

• Mileage should increase each year
• If mileage goes DOWN, the car has been clocked
• Suspiciously static mileage is also a red flag

Check with our free MOT checker.

2. Wear Doesn't Match Mileage

A "30,000 mile" car shouldn't look like it's done 130,000:

3. Service History Gaps or Inconsistencies

• Missing service stamps during key mileage periods
• Mileage in service book doesn't match MOT records
• Suspiciously new-looking service book
• Only recent services documented

4. Replacement Parts Don't Add Up

Some parts need replacing at certain mileages:

• Timing belt: Usually at 60k-100k miles
• Clutch: Typically lasts 60k-100k miles
• Brake discs: Often need replacing around 50k-70k

If a "40,000 mile" car has had these replaced, ask why.

5. Price Too Good to Be True

A car priced well below market value for its apparent mileage could be clocked. The seller knows it's worth less than advertised.

How to Check If a Car Has Been Clocked

Step 1: Check MOT History

Use our free MOT checker to view every recorded mileage:

1. Enter the registration number
2. Look at mileage at each MOT
3. Check it increases consistently each year
4. Compare current odometer to last MOT reading

Step 2: Run a Full History Check

Our vehicle history check provides:

• Enhanced mileage analysis
• Mileage anomaly flags
• Data from multiple sources
• Historical mileage timeline

Step 3: Review Service History

Cross-reference mileage in:

• Service book stamps
• Dealer service records (call to verify)
• Oil change stickers
• Cam belt replacement records

Step 4: Physical Inspection

Compare wear to claimed mileage. Trust your instincts—if it looks like a high-mileage car, it probably is.

Step 5: Ask Questions

• Can you verify the mileage with service records?
• Why is it priced below similar cars?
• What's the car's history?
• Watch for evasive answers

High-Risk Vehicles for Clocking

Some cars are more likely to be clocked:

Ex-Fleet and Company Cars

• Often high mileage from business use
• Clocked before auction to improve sale price
• Multiple drivers means more wear

Imports

• Foreign mileage records harder to verify
• Kilometers sometimes "converted" incorrectly
• Less paper trail to check against

Ex-Lease Returns

• May be clocked to avoid excess mileage charges
• High-mileage drivers have incentive to cheat

Popular Models

• High-demand cars are targeted more often
• Ford Focus, VW Golf, BMW 3 Series, Audi A4
• Easier to sell, more profitable to clock

What to Do If You've Bought a Clocked Car

If you discover your car has been clocked:

Private Purchase

• Contact the seller: Request a refund (they may refuse)
• Report to Trading Standards: They can investigate
• Report to Action Fraud: 0300 123 2040
• Consider legal action: Small claims court for lower values

Dealer Purchase

• Consumer Rights Act 2015 applies: You have stronger protection
• Request refund: Car was not as described
• Contact Trading Standards: If dealer refuses
• Credit card protection: Claim through Section 75 if paid by card

Evidence to Gather

• MOT history printout showing discrepancy
• Photos of wear inconsistent with mileage
