The UK government is weighing stricter action against criminals exploiting radio frequency jammers—devices capable of disrupting wireless communications and undermining everyday security

systems. Ministers have launched a fresh push to address the growing misuse of these tools, which are increasingly linked to theft, public safety risks and threats to national infrastructure.

Originally designed for legitimate, controlled environments, jammers are now being repurposed by criminals to block GPS tracking in stolen vehicles, disable video doorbells during burglaries and interfere with wireless alarm systems. In some cases, the devices are disguised as ordinary household items, allowing offenders to operate unnoticed while breaking into homes or vehicles. Retailers have also reported their use in shoplifting, where jammers can prevent security tags from triggering alarms.

Beyond theft, officials warn the impact could be far more serious. Interference with mobile networks and emergency radio systems risks slowing response times for police, fire and ambulance services. There are also concerns about their potential to disrupt military operations.

The economic consequences could be severe. Government estimates suggest that just one week of disruption to the UK’s positioning, navigation and timing systems—critical for sectors ranging from transport to finance—could cost up to £7.62 billion.

In response, ministers are seeking input from the public, industry experts and key sectors including telecoms, transport and law enforcement. The consultation will examine whether current laws are sufficient and how enforcement could be strengthened.

Telecoms Minister Liz Lloyd said the government is “stepping up efforts” to tackle the illegal use of jamming devices, describing them as a threat not only to daily life but also to essential public services. She added that the consultation offers an opportunity to shape future safeguards for homes, businesses and infrastructure.

While the use and possession of non-compliant devices is already banned under the Wireless Telegraphy Act 2006, securing convictions has proven difficult, particularly when it comes to proving intent to interfere with communications. New proposals under the Crime and Policing Bill aim to close some of these gaps, including making it illegal to possess or distribute electronic tools used in vehicle theft—offences that could carry prison sentences of up to five years.

The government says the findings from this consultation will help determine whether broader restrictions on jammer possession are needed, while also clarifying legitimate uses—such as in prisons to block illicit mobile phone use or during military training exercises.

Any future legislation, ministers insist, will be guided by evidence and designed to strike a balance between security and legitimate operational needs, while protecting the UK’s critical infrastructure from emerging technological threats. Photo by UrusHyby, Wikimedia commons.
