Signal jammers are increasingly implicated in vehicle thefts, particularly targeting high-value and luxury vehicles. These devices interfere with and override remote locks, allowing thieves to gain entry without a key or forced entry.
According to the Crime Survey for England and Wales, signal jammers were linked to approximately 40% of vehicle thefts in 2022/23. In London specifically, the Metropolitan Police estimate their involvement at 60%.
The Crime and Policing Bill, introduced to Parliament on 25 February 2025, proposes substantial changes to the legal consequences for individuals found in possession of signal jamming devices.
Previously, under the Wireless Telegraphy Act 2006, prosecution for possession of such equipment required proof that it had been used to commit a crime, and deliberate interference with wireless signals was punishable by up to two years’ imprisonment and/or a fine.
The new Bill shifts the legal framework by reversing the burden of proof and increases the maximum penalty to five years’ imprisonment and/or an unlimited fine. Those caught with the devices must demonstrate a justifiable, legitimate purpose for possession. As a result, mere possession or the intention to use the device can now give rise to criminal liability.
The legislation is expected to enhance the powers of courts and police officers to investigate and prosecute those who use, produce, or distribute these devices.
Those operating within the motor trade should exercise caution. Traders who knowingly or inadvertently sell vehicles equipped with signal jammers may be exposed to criminal liability.
