Sainsburys facial recognition trial in shops sparks privacy debate and industry scrutiny

Sainsbury’s, the UK’s second largest supermarket chain, has commenced an eight-week pilot of facial recognition technology at selected stores in Sydenham, south-east London and Oldfield Park in Bath. The move, aimed at combating the rising tide of shoplifting and retail crime, comes amid a surge in recorded offences, which officially soared to over half a million last year in England and Wales—a record high.

The retailer is partnering with Facewatch, a facial recognition enterprise already utilised by retailers such as Home Bargains and Sports Direct. The technology is intended solely for identifying individuals known for acts of violence, aggression, or theft. According to Sainsbury’s, any facial data not matching submitted reports will be instantly deleted. Alerts are generated based on criminal behaviour reported by Sainsbury’s or nearby shops also using the Facewatch system.

Simon Roberts, Sainsbury’s chief executive, explained the rationale behind the trial, stating: “We have listened to the deep concerns of our colleagues and customers who expect strong action. With the ongoing rise in abuse, antisocial behaviour and violence, prioritising safety is paramount. Our approach focuses strictly on serious offenders, not on monitoring staff or valued customers.”

Despite assurances from the company, privacy advocates remain unconvinced. Big Brother Watch, a prominent privacy campaign organisation, decried the initiative as “deeply disproportionate and chilling”, and called for both Sainsbury’s and the government to halt the deployments. Previous trials, such as Asda’s earlier this year, provoked thousands of complaints amid growing unease about the spread of biometric surveillance in commercial settings.

The Equality and Human Rights Commission has also voiced concerns, warning that the use of such technologies risks being intrusive and could have a chilling effect on personal rights. Research indicating a higher likelihood of alerts being triggered for black men has intensified apprehensions around potential biases in facial recognition systems.

Retail industry groups and union representatives have expressed hope that the pilot’s results will provide valuable insight into balancing staff and customer safety with responsible technology usage. Joanne Thomas, general secretary of Usdaw, welcomed Sainsbury’s commitment to protecting workers, emphasising the need for evidence-led solutions to retail crime. The outcome of the trial could shape future security strategies across the sector, as industry players weigh the benefits and societal risks of adopting advanced surveillance tools.
