Drug trafficking remains a major enforcement priority at the UK border, with police and customs agencies recording large volumes of controlled substances each year. Seizure activity is used by authorities as a direct measure of disruption against organised crime supply chains.
Border Force and police recorded a record year of drug seizures to March 2025, according to new Home Office figures published on 12 February 2026. Nearly 150 tonnes of illegal drugs with an estimated £2.6 billion street value were intercepted, with cannabis, ketamine and nitrous oxide at all-time highs.
The update also reports record cocaine seizure volumes by police and confirms nationwide rollout of the Seize and Return policy for foreign cannabis smugglers.

Maritime and Port Enforcement Operations
Border Force states that organised crime groups are increasingly using maritime routes and at-sea transfer methods. The release cites a January case where 1.5 tonnes of cocaine valued at just under £60 million was detected on a vessel arriving into Dover from Peru.
The agency also reports a September case involving one tonne of cocaine concealed inside two industrial generators valued at £720,000. The operational effect described is increased disruption of concealment techniques through port and vessel searches.
Technology and Specialist Detection Methods
Border Force reports the use of high-technology search equipment and specialist deep-search officers for ships and vessels. The Home Office states these capabilities are used to detect concealed drugs and restricted goods at the border.
The release names joint working between Border Force, police forces and the National Crime Agency using intelligence and technology. The stated effect is coordinated enforcement across agencies targeting organised crime networks involved in drug trafficking.

Stakeholder Comments
Ministerial Comments
Mike Tapp, Home Office Minister said;
“Drug seizures are at a record high under this government – with British law enforcement depriving evil gangs of almost £3billion worth in one year alone. Every seizure strikes a blow at the heart of organised crime and stops dangerous drugs from inflicting misery on our communities. We will continue to do whatever it takes to secure Britain’s borders against those doing harm to our country.”
Phil Douglas, Border Force Director General said;
“Our innovative Seize and Return policy is delivering real results – removing smugglers within hours, saving taxpayers millions, and freeing up our officers to pursue the organised crime gangs that cause the most harm. Border Force will continue to be relentless in our pursuit of dangerous criminal networks and disruption of drug supply.”
In Conclusion
The Home Office and Border Force dataset for the year to March 2025 records the highest total drug seizure volumes and interception events since records began. Published figures link tonnage, seizure counts and substance categories to named operational policies and enforcement methods.
The release presents quantified outcomes, named agency actions and ministerial statements as the basis for the record claim, with measurable indicators tied to border operations and inter-agency cooperation.
