Sainsbury’s has confirmed plans to introduce facial recognition technology in up to 150 more UK stores before Christmas, building on a successful trial that has already deterred over 90% of identified offenders from returning.
Expansion Details and Timeline
The supermarket chain announced the expansion in its first quarter trading statement on June 30, 2026. The technology is currently live in more than 55 stores and will be rolled out to up to 150 additional locations by the end of the year. Sainsbury’s said the move is part of its commitment to “keep people safe” and follows a trial that began in September 2025.
Trial Results and Impact on Crime
A report published by the retailer in January 2026 highlighted encouraging early results from trials at its Sydenham and Bath Oldfield Park stores. These locations saw a 46% reduction in theft, harm, aggression and antisocial behaviour, while 92% of offenders did not return. Following these results, the technology was extended to five further London stores in Dalston, Elephant and Castle, Ladbroke Grove, Camden and Whitechapel.
According to Sainsbury’s, the Facewatch system used in its stores has a 99.98% accuracy rate. Every alert generated by the system is reviewed by trained colleagues before any action is taken. The retailer emphasised that the system is designed solely to identify individuals who have previously shown violent, aggressive or criminal behaviour in participating stores, and is not used to monitor everyday shoppers or colleagues. If the system does not recognise someone, the image is deleted instantly.
Safety Measures and Customer Communication
Sainsbury’s said clear signage is in place in all stores that use the facial recognition technology so that customers know it is in operation. The retailer added that it plans to introduce the technology into more stores nationwide. The use of facial recognition comes after Sainsbury’s became the first UK retailer to roll out colleague-worn cameras in 2018, and it has since added further protective measures including security officers, in-store detectives, entry barriers, protective screens and enhanced product security.
Company Statement and Context
Confirming the plans, Sainsbury’s said in its quarterly trading statement: “We remain on track to deliver £1 billion of cost savings over the three years to March 2027, investing in technology and infrastructure to drive operational efficiency whilst improving customer experience.” The statement also noted that the retailer has brought together leadership of stores, supply chain and logistics, and restructured its retail management team to bring focus to supermarket, convenience and digital channels.
Explaining the use of the technology in January 2026, Sainsbury’s said: “We know privacy matters deeply to people. That’s why our use of this technology has been designed with strong safeguards. The Facewatch system has a 99.98% accuracy rate and every alert is reviewed by trained colleagues before any action is taken.
“The system is designed solely to identify individuals who have previously shown violent, aggressive or criminal behaviour in participating stores - it is not used to monitor everyday shoppers or colleagues. If the system does not recognise someone, the image is deleted instantly.
“Sainsbury’s has a long record of leading the way on store safety and we will continue to invest in measures that support our colleagues and create secure, welcoming places to work and shop.
“Colleagues should never feel at risk while doing their jobs and customers should always feel comfortable in our stores. That’s why we are taking these steps and why we will continue to put safety first across every part of our business.”
