Tech Insight : More UK Retailers Using Surveillance

In this Tech Insight, we look at how retailers across the UK are deploying new technology to deter shoplifting, reduce abuse of staff plus gather better evidence, whilst retail crime hits record levels.

Why Retailers Are Acting Now

The British Retail Consortium’s Annual Crime Survey reports losses from customer theft reaching £2.2 billion in 2023/24 and over 20 million shoplifting incidents, while violence and abuse against retail workers rose to more than 2,000 incidents per day. Retailers simultaneously lifted spending on prevention to £1.8 billion, yet it seems that satisfaction with police response remains low, with 61% rating it “poor” or “very poor”. “Retail crime is spiralling out of control,” said BRC chief executive Helen Dickinson, calling for industry, government and police to act together.

Figures from the Institute of Customer Service (ICS) provide more service sector context. For example, 42 per cent of public‑facing workers reported abuse in the prior six months, up 19 per cent year on year. 37 per cent even said they had considered quitting, and over a quarter said they had taken sick leave, according to figures highlighted in national coverage of ICS’s “Service with Respect” campaign and open letter urging stronger legal protections for all service workers.

Bodycams On The Shop Floor

It may surprise many people to know that body‑worn video is now commonplace across parts of the high street. For example, Poundland originally reported an 11 per cent drop in violence after rolling out Motorola Solutions VT100 cameras, with footage managed via Motorola’s evidence platform and linked to CCTV. It should be noted here that Poundland has since been sold (by Pepco Group to Gordon Brothers’ Peach Bidco for £1 on 12 June 2025) and it’s not clear if it’s still using the cameras. Another popular high street name, H&M, is piloting bodycams in three UK stores to test impact on de‑escalation and incident reduction. Also, Tesco now uses bodycams for store and some delivery colleagues, activated when staff feel unsafe. EE even equips store teams with cameras that can stream incidents to monitoring teams. These measures are all intended both to act as visible deterrents and to strengthen evidence for police.

Facial Recognition Trials Move Into The Mainstream

Some chains are trialling facial recognition to identify repeat offenders linked to theft or abuse. For example, Sainsbury’s is running an eight‑week pilot with Facewatch in selected stores in London and Bath, where alerts are generated only when someone on a store‑defined watchlist enters. In terms of how effective it could be, Iceland has reported that its early use of Facewatch led to a 30 per cent reduction in violent incidents where deployed, and that it plans a further roll‑out of the technology later this year. Southern Co‑op and other retailers have used similar watchlist alerts for several years.

Retailers say that systems focus on known repeat offenders and that signage is used at trial sites. Sainsbury’s has framed the pilot as a staff‑safety measure in locations with high repeat offending. Iceland’s Richard Walker argued publicly that the technology helps trained store teams to make calm, proportionate interventions.

AI‑Enhanced CCTV And “Smarter” Monitoring

Beyond face matching, retailers are also now trialling AI‑assisted video analytics that compare what shoppers pick up with what is scanned, flagging likely non‑scans in real time. For example, Trigo Retail recently launched a computer‑vision loss‑prevention platform in the UK that tracks shopping behaviours without storing biometric identifiers, thereby aiming to provide targeted alerts rather than blanket monitoring. As Trigo co‑founder Daniel Gabay recently said, “The most effective retail security technology today isn’t about adding more barriers or locks, it’s about making existing infrastructure smarter”.

Security Hubs, Headsets And Digital Crime Reporting

Tesco has set up a 24/7 national Security Operations Centre in Daventry to analyse thousands of hours of CCTV, join up evidence and share intelligence with police. The supermarket says the hub monitors clusters of stores and operates year‑round.

In a different approach, Currys has opted to roll out VoCoVo headsets across stores so colleagues can call for support instantly and coordinate responses. It has also taken Auror’s crime‑reporting platform nationwide after a 12‑week trial identified 10 repeat offenders, led to three arrests, and prevented about £20,000 of theft. Currys also cites a 58 per cent year‑on‑year reduction in aggressive incidents during March–April. The company says incident logging is faster and more consistent, supporting police engagement.

The Home Secretary has publicly urged more UK retailers to use crime‑intelligence platforms like Auror and signalled support for broader data‑sharing with police where lawful and proportionate.

Fogging Devices And Smart Safes

Alongside analytics and reporting, several retailers are investing in fogging and misting systems that rapidly fill areas with disorienting fog during an incident, forensic marking to tag stolen goods for later recovery, and time‑delay stock safes for high‑value items. EE says these measures, combined with tracking tools for stolen devices, are reducing opportunities for smash‑and‑grab theft and improving staff safety.

Is The Technology Actually Working?

In terms of whether these hi-tech approaches to tackling crime are actually working, it seems that some deployments are reporting measurable impact. For example, Poundland’s reported 11 per cent reduction in violence post‑bodycams does appear to indicate a deterrent effect when incidents are recorded and evidence quality improves. Also, Currys’ 58 per cent drop in aggressive thefts during a focused period, along with identified repeat offenders and arrests, could suggest that intelligence‑led reporting can help direct police resources. However, results vary by store, offender behaviour can displace to nearby locations, and none of these tools replace visible policing.

What Privacy Groups Are Saying

Privacy advocates argue that live facial recognition in shops risks normalising biometric checks for everyday purchases and can harm people when errors occur. For example, Big Brother Watch has urged Sainsbury’s to stop its trial, calling the approach “deeply disproportionate and chilling”, and warning that it “turns shoppers into suspects”. The group also raises concerns about privately run watchlists, limited transparency, and the lack of robust redress when people are wrongly flagged.

Campaigners also point to documented cases and regulatory complaints in which customers were allegedly misidentified in stores using commercial facial recognition. In one case, a woman said she discovered she had been placed on a Facewatch watchlist after a dispute over low-value goods, prompting a complaint to the regulator about necessity and proportionality. Such incidents underline why rights groups want independent oversight, strict targeting to serious repeat offending, and clearer routes to challenge mistakes.

The Information Commissioner’s Office describes facial recognition in public-facing spaces as highly intrusive, and expects organisations to complete a Data Protection Impact Assessment for each deployment, show a strong lawful basis, and evidence that less intrusive methods would not achieve the aim. The regulator’s guidance also stresses governance around watchlists, meaningful human review of matches, recording and correcting false positives, careful data retention, and transparency with clear signage.

The Evolving Legal And Policy Picture

Ministers have pledged to create a standalone offence of assaulting a retail worker in the forthcoming Crime and Policing Bill, and signalled plans to remove perceived barriers to charging thefts under £200. Trade bodies are pressing for police to attend incidents more routinely, and for protections to extend to a wider group of public-facing roles. For retailers piloting facial recognition or AI video analytics, compliance is practical and specific, i.e. to set out a clear lawful basis and DPIA, evidence necessity and proportionality, display clear signage, apply tight retention periods with human review of matches, and provide straightforward routes for people to challenge mistakes.

Operational Reality For Businesses

Understandably, it seems that retailers are focused on what actually works in-store. For example, body cameras are known to deter aggression and produce evidence that can be used. Also, AI video systems can spot items that are not scanned and tighten loss prevention without adding physical barriers. Store headsets and digital crime reporting speed up responses and improve the quality of referrals to the police, and central security hubs connect patterns across regions and help investigations move faster.

It should be noted, however, that introducing these measures is not simply a case of just plug and play. It needs training for staff, clear procedures, and close working with local police so that evidence gathered in store is followed up.

Competitors, Customers And Others

With the use of this kind of tech by some retailers, competitors face a strategic question, i.e. if early adopters show clear reductions in violence and stock losses, others are likely to follow or risk falling behind on safety and loss‑prevention. For customers, the line between protection and surveillance needs careful management to maintain trust. Clear signage, narrow watchlists, rapid deletion of non‑matches and accessible complaint routes matter for legitimacy. For staff and unions, evidence that measures reduce assaults and abuse will be critical to ongoing support. For regulators and campaigners, the priority remains ensuring deployments are narrowly tailored, evidence‑led and subject to meaningful oversight.

Key Challenges To Watch

It seems, however, that questions remain about how these measures perform in real stores. For example, evidence is still building and can vary by location, store format and offender behaviour. Also, facial recognition carries a risk of misidentification, so there must be strong human review and clear routes to correct mistakes. Data retention, watchlist criteria and any information sharing need tight governance and regular audit. Without consistent police follow up, even well documented incidents may not progress, which reduces the deterrent that retailers and staff are looking for.

What Does This Mean For Your Business?

It seems that technology has now moved from trial to toolkit. Bodycams, AI-supported CCTV, crime reporting platforms and central security hubs are all reportedly delivering practical gains where deployments are targeted, well trained and supported by local policing. Facial recognition remains the most contested, which is why governance, human review and visible transparency need to be embedded from the start. None of this is a silver bullet, it is a set of controls that work best together and only when the basics of staff training and incident follow up are in place.

For UK businesses the lesson is to invest where the benefits are clear, measure results store by store, and publish what works so staff and customers can see the value. Build privacy and accuracy into the design, with narrow watchlists, short retention periods and simple routes for people to challenge mistakes. Engage early with police, unions and regulators so evidence gathered in store is acted on, not left on a server. Competitors that delay now look like risking higher losses and lower staff confidence, while those that proceed without robust safeguards risk reputational damage and regulatory attention.

For customers, trust depends on openness and restraint. Clear signage, clear explanations and visible accountability help reassure people that security measures are there to protect, not to monitor ordinary shopping. For staff, the test is whether incidents decline and confidence rises, which should be tracked through surveys and incident data.

Featured Article : Sainsbury’s Facial Recognition Combats Shoplifting

Sainsbury’s has begun testing facial recognition technology in selected stores to identify repeat offenders and reduce shoplifting, triggering a wave of privacy concerns from civil liberties groups.

Surveillance Trial Rolling Out in London and Bath

The supermarket chain confirmed that an eight-week pilot programme is underway at a small number of stores in London and Bath. The facial recognition cameras are supplied by Facewatch, a UK-based security technology firm that already provides similar services to a range of retailers.

The system captures the biometric data of individuals who are already on a watchlist for suspected theft or abuse. If someone flagged on this list enters a participating store, an alert is sent to staff in real time. Sainsbury’s says the trial is being used only at locations with a high incidence of repeat offending.

The trial began in late August and is expected to run through to October. Depending on results, it could be expanded to more branches across the UK. Facewatch claims its technology can help retailers cut shoplifting and abuse by deterring known offenders and giving staff more time to intervene safely.

Why Sainsbury’s Is Doing This Now

Retail crime has surged in recent years, with the British Retail Consortium (BRC) estimating the total cost to the sector at £1.76 billion in 2023, including £1.04 billion in customer theft alone. Also, physical assaults and abuse of shop workers have also been rising sharply, prompting calls for tougher enforcement and more robust security measures.

Sainsbury’s said in a statement: “We’re constantly looking at new ways to keep our colleagues and customers safe. We’re currently trialling facial recognition in a small number of stores where there is a high level of crime.”

Signage About It

The company emphasised that the technology is not being used for general customer surveillance or profiling, and that signage is in place at affected locations to notify shoppers that facial recognition is in use.

Powered by Facewatch (Controversially)

The system being used by Sainsbury’s is provided by Facewatch, a private facial recognition firm founded in 2010. Facewatch says it operates within UK GDPR and the Protection of Freedoms Act 2012, and only stores data on those individuals who have been involved in past incidents, as reported by retailers.

Its technology compares live CCTV footage to images held in its centralised database of “subjects of interest.” If there is a match, an alert is sent to store staff with a still-image and time-stamped location data.

While Facewatch has been used by independent retailers, petrol stations and other supermarket chains including Southern Co-op and Budgens, it has not previously been adopted by any of the UK’s four major supermarket brands at this scale.

It seems that the company has drawn some criticism from privacy campaigners for operating a privately managed watchlist system that can share biometric alerts between businesses, with concerns raised about accuracy, accountability, and the lack of independent oversight.

The move by Sainsbury’s essentially takes facial recognition further into the retail mainstream and puts the technology under new levels of public and regulatory scrutiny. It also raises the stakes for how and where this kind of surveillance may be used next across the sector.

Privacy Groups Push Back

Civil liberties organisations were quick to voice concerns. For example, Big Brother Watch, a UK privacy campaign group, accused Sainsbury’s of introducing “unnecessary and Orwellian” surveillance under the guise of crime prevention.

“Facial recognition surveillance is extreme, and Sainsbury’s customers should not be subjected to identity checks to buy milk,” said Madeleine Stone, Senior Advocacy Officer at Big Brother Watch. “This sets a dangerous precedent not just for retail, but for everyday public life.”

The group also raised concerns about transparency and consent, arguing that biometric surveillance in shops blurs the line between policing and commerce. It warned that the use of facial recognition could result in misidentifications, discrimination, and the over-policing of vulnerable groups.

The Information Commissioner’s Office (ICO) has previously cautioned organisations using facial recognition to ensure legal compliance and necessity. It has not commented directly on the Sainsbury’s trial but is likely to monitor developments closely.

Facewatch’s Role in Expanding Everyday Surveillance

Sainsbury’s pilot sits within a broader shift where facial recognition is moving from niche deployments to visible use in everyday retail settings. Southern Co‑op has used Facewatch across dozens of branches since 2020, while independent convenience stores and some symbol groups have reported measurable reductions in repeat theft when using similar watchlist alerts. In one Morrisons Daily site, the store owner told trade press that incidents dropped by as much as ninety per cent after installation, though these results are self‑reported rather than independently audited.

Other Big Chains Are Already Testing the Waters

Other large grocers have been testing live facial recognition in recent months. For example, Asda ran a trial across five Greater Manchester stores, drawing thousands of complaints and sustained criticism from privacy groups, which shows how quickly public reaction can become a material factor in rollouts. Iceland has also been named by campaigners as exploring use, although details remain limited. These parallel efforts are relevant to Sainsbury’s because they indicate how public tolerance, operational benefits, and regulatory scrutiny interact in real retail environments.

Concerns About Accuracy and Misidentification

Concerns about accuracy and fairness remain central to the debate about the use of this kind of technology. For example, privacy group Big Brother Watch argues that commercial watchlists risk misidentifying innocent shoppers because entries are often created by retailers rather than police and can be shared between participating businesses. The group says this creates a risk of people being wrongly flagged and excluded. There have been reported misidentifications, including a case where a customer was barred after a Facewatch alert, which Facewatch later acknowledged was an error. These cases are shaping campaigners’ calls for stricter safeguards and clearer lines of accountability.

Legal Uncertainty Around Commercial Use

The policy landscape adds another layer. For example, the UK has no dedicated statute that comprehensively governs private sector facial recognition in public‑facing spaces, so retailers largely rely on data protection law, necessity and proportionality tests, and DPIAs to justify deployments. The ICO has previously investigated Facewatch and related deployments and, according to evidence submitted to Parliament, identified multiple areas where policies needed to better balance legitimate interests with people’s rights. This context frames what retailers must document and evidence when running pilots like Sainsbury’s.

How the Trial Is Being Measured

Operationally, Sainsbury’s says the Facewatch system is configured to alert staff only when a person on a pre‑defined watchlist is detected, focused on individuals linked to violence, aggression, or theft. Faces that do not match are deleted immediately, and signage at trial stores informs customers that facial recognition is in use. The supermarket has also stressed that the pilot is limited to locations with high levels of repeat offending, and that it is intended to support staff safety rather than to monitor ordinary shoppers.

Retail Crime Data Is Driving Urgency

Evaluation will centre on measurable changes in repeat theft and abuse, staff perceptions of safety, and any displacement effects, for example incidents shifting to nearby stores. The British Retail Consortium reports retail theft at crisis levels, with more than twenty million incidents in 2023 to 2024 and an estimated £2.2 billion lost to shoplifting, which explains why large chains are testing additional controls alongside guards, body‑worn cameras, and product protection. These sector‑wide figures provide the baseline against which any impact from facial recognition will be assessed.

Public Reaction Will Influence Industry Direction

It’s likely that public response will also form part of the assessment. Big Brother Watch has labelled the Sainsbury’s pilot “deeply disproportionate and chilling,” arguing that biometric scanning in supermarkets treats shoppers as suspects and risks normalising identity checks for everyday purchases. Trade unions have tended to frame the question through the lens of staff safety, calling for evidence‑led approaches that reduce violence and abuse at work. Therefore, how these competing views evolve during the pilot will influence whether other national chains follow Sainsbury’s lead.

Regulatory Input Could Shape What Comes Next

Also, any regulatory feedback could shape the design of future deployments. For example, if the ICO receives complaints during the trial, it may seek clarifications on data retention, watchlist criteria, redress routes for mistaken identity, and transparency notices. Previous facial recognition pilots in retail and other sectors have drawn attention to these governance questions, so documenting them clearly is likely to be as important as any headline reduction in theft.

What Does This Mean For Your Business?

The outcome of this trial will matter not only for Sainsbury’s but for any UK business operating in high-footfall environments where theft, abuse, or anti-social behaviour is on the rise. If facial recognition is shown to reduce repeat offending without undermining customer trust, other sectors may begin exploring similar systems, from retail and hospitality to logistics and healthcare. However, that will depend on clear governance, strong safeguards, and public confidence in how the technology is being used.

For technology providers, the stakes are also high. For example, Facewatch’s credibility as a supplier of compliant, proportionate, and accurate surveillance tools may hinge on how this pilot is received by regulators and rights groups. If the ICO intervenes or public backlash intensifies, it could limit how far these systems can expand. Businesses adopting facial recognition will need to be ready to justify every aspect of its deployment, from necessity and proportionality to data handling and redress.

For consumers and communities, the case raises fresh questions about what kind of monitoring is acceptable in everyday spaces, and where the boundaries lie between legitimate protection and excessive surveillance. The lack of specific legislation leaves a vacuum where privacy, ethics, and commercial interest are all pulling in different directions. Without clear national rules, it may fall to individual retailers, campaigners, and regulators to shape how far this goes.

As the pilot continues, attention will turn to how Sainsbury’s measures success and handles concerns. Whether this becomes a new layer of shopfloor security or a short-lived experiment will depend on what the results show, how they are interpreted, and whether wider industry and political appetite supports rolling it out further.
