The unusual reason why chocolate is now sold under lock and key in the UK

In British supermarkets, a new anti-theft measure is catching shoppers’ attention: chocolate bars are now being stored in locked plastic security boxes. Each bar has its own case, and only store employees can open it. The move comes in response to warnings from law enforcement, which has flagged multiple cases of organized shoplifting targeting supermarkets.

The Association of Convenience Stores (ACS) has echoed police concerns, warning that chocolate has “become a more frequent target for repeat offenders.” Sainsbury’s, the second-largest supermarket chain in the United Kingdom, told the BBC that some of its stores have started using “security boxes on products that are regularly targeted,” including Cadbury Dairy Milk bars at one London location.

The National Police Chiefs’ Council has confirmed that chocolate theft is a real and growing trend, saying police are doing what they can to tackle it. In recent months, authorities have also circulated surveillance footage of chocolate thefts to raise awareness. In one example, West Midlands Police released security camera footage from a store in Stourbridge showing a man stealing trays of chocolate from the premises.

Other police departments have shared similar incidents. In one case, Wiltshire Police released video showing a man dragging an entire shelf loaded with chocolate bars out of a store. Cambridgeshire Police also highlighted the issue in early 2025, reporting that a man had been arrested while allegedly carrying a coat stuffed with chocolate eggs. “Chocolate is one of the high-value items commonly stolen by thieves, along with products such as alcohol, meat, and coffee,” police told the media.

Losses of up to $310,000

The rise in chocolate theft is part of a broader wave of retail shoplifting across the United Kingdom. According to the annual crime report from the British Retail Consortium, a total of 5.5 million shoplifting incidents were recorded in 2025, along with 1,600 daily incidents of violence and abuse against retail workers. That was the second-highest figure on record, behind 2024, which was 20% higher.

As a result, stores such as Tesco, Co-op, and Sainsbury’s are increasingly filling their shelves with chocolate bars locked inside plastic security cases. The Heart of England Co-op told the media it had suffered losses of up to £250,000, or about $310,000, due to repeated chocolate thefts in its stores. According to the company, chocolate was the most frequently stolen product in 2024 and was surpassed only by alcohol in 2025.
