Are Mileage Blockers Illegal in the UK?

Mileage Blockers are specialist electronic modules intended for controlled testing environments, including dyno testing, diagnostics, track days and off-road use. They should not be used to hide, disguise or misrepresent a vehicle’s true mileage, condition, value, service history, finance usage or road use.

Modern vehicles can store mileage and usage-related data across multiple systems, so any mileage discrepancy should be handled transparently and responsibly.

Legal Status

In the UK, it is not illegal to own or install a mileage blocker. However, using a mileage blocker to deceive potential buyers or during MOTs, services, or any legal documentation is illegal under the Consumer Protection from Unfair Trading Regulations 2008. Failure to disclose altered mileage when selling a vehicle can result in severe legal consequences, including prosecution for fraud.

Consequences Of Using Mileage Blockers

Using a mileage blocker with the intent to deceive can lead to charges of fraud, heavy fines, and even imprisonment. The vehicle’s history is traceable, and Mileage Blockers are virtually impossible to discover unless they are physically left in the vehicle. If they are left in the vehicle discrepancies may be uncovered during routine checks, leading to potential legal action. As long as they are removed they leave no footprint in the vehicle’s Speedometer, ECU, BCM or Key Modules making it virtually impossible to find even with dealer diagnostic tools. Moreover, any individual or business selling a vehicle with an undisclosed mileage alteration can face significant reputational damage and potential legal penalties.

Why Are Mileage Blockers In The News?

Mileage blockers have gained attention due to the rise in fraudulent activity, where these devices are used to inflate vehicle prices. Despite their intended use being limited to off-road purposes, the ease of access and installation has led to widespread misuse, but we don’t condone this in any way shape or form and only sell them based on the intended legal purpose.

Consumers should always check the vehicle’s service history, compare the MOT history and vehicles condition, make their own judgement, and be wary of deals that seem too good to be true. It is advisable to seek a professional vehicle inspection before purchase, although a diagnostic tool won’t be able to tell you if a mileage blocker has been used, a professional maybe able to advise you if they think the mileage maybe incorrect.

Conclusion

While mileage blockers themselves are not illegal in the UK, their misuse certainly is. Any attempt to deceive others regarding a vehicle’s mileage can lead to severe legal consequences. If you are considering purchasing a vehicle, ensure that you conduct thorough checks to avoid falling victim to mileage fraud.
