UK Prisons Overwhelmed by Drone Drug Crisis as Security Systems Fail
A damning new report has exposed how UK prisons are being overwhelmed by a surge in drones delivering drugs and contraband, with vital security systems left broken for months and critical budget underspends hampering the response. The National Audit Office (NAO) investigation reveals that organised criminal gangs are exploiting vulnerabilities in prison security, with authorities struggling to keep pace with the rapidly evolving threat.
Security Systems Left Unrepaired for Months
Prison governors have told the UK's independent public spending watchdog that they lack the resources to meet escalating security demands. This comes despite HM Prison and Probation Service (HMPPS) spending only 75 per cent of its £100 million security investment programme budget between 2019-2020 and 2021-2022. The report highlights that broken security equipment, including essential X-ray scanners for prisoners' luggage, has gone unrepaired for several months in many institutions.
Drone Incidents Skyrocket Across England and Wales
The scale of the problem is staggering. Between April 2024 and March 2025 alone, there were 1,712 recorded drone incidents at prisons across England and Wales. Detective Chief Superintendent Lewis Hughes of Greater Manchester Police emphasised the challenge, stating: "We don't police the airspace. Organised criminals have cottoned on to the fact that it's very difficult to target and intercept drones. It’s a growing and evolving problem."
Budget Shortfalls and Maintenance Backlogs Compound Crisis
The report identifies severe financial mismanagement that has left prisons dangerously exposed. A prison maintenance backlog doubled from £0.9 billion to £1.8 billion between 2020 and 2024. Furthermore, HMPPS was allocated £97 million between 2022-2023 and 2024-2025 as part of the government's 10-year drug strategy, From Harm to Hope, but spent only £67 million of this funding.
Widespread Drug Problems Among Prison Population
The consequences of these security failures are dire. In April 2025, around 50 per cent of the prison population in England and Wales – approximately 40,000 people – had an identified drug problem. Gareth Davies, head of the NAO, warned: "The proliferation of illicit drugs in prisons undermines rehabilitation, damages health, and destabilises prison environments. Yet too many of the basic controls and interventions are not being done well enough."
Government Response and Health Service Delays
In response to the crisis, the government invested £40 million in 2025 towards high-risk prisons to improve security measures, including adding window grilles and anti-drone netting. However, the NAO has also called for better coordination with health services, revealing that in 2024 to 2025, a quarter of prisoners with potential substance misuse needs waited more than three weeks for an NHS England health assessment.
Prisons minister Lord Timpson acknowledged that historical underinvestment in security has contributed to "unacceptable" drug levels, stating the government is taking "decisive action" to address the crisis. He highlighted investments in anti-drone measures and increased support for offenders battling addiction, including funding for substance-free units and deploying specialist staff. The NAO's recommendations aim to help direct resources where they can have the greatest impact on this serious and escalating problem.
