Government Secretly Tracked 25 Million Phones

The UK government secretly tracked 25 million mobile phone users over two years to identify who might be driving electric vehicles, turning ordinary citizens into surveillance targets without their knowledge or consent.

Story Snapshot

Department for Transport paid O2 £600,000 to monitor 25 million devices from 2022-2024, flagging users who visited EV websites twice in two months
Data collection included children and passengers, not just drivers, across O2 networks including Sky Mobile, Tesco Mobile, GiffGaff, and Virgin Mobile
Revelation emerged in February 2026 when DfT published its report, sparking cross-party criticism as surveillance state overreach
Timing proves suspicious as pay-per-mile EV taxation launched just as tracking concluded in April 2024

Big Brother Comes to Your Driveway

The Conservative government authorized the Department for Transport’s Advanced Analytics Division to purchase mobile browsing data from O2 in 2023, targeting regions with high EV adoption rates including London, northwest England, and eastern England. The scheme flagged anyone visiting EV-related websites or apps at least once monthly for two consecutive months. That definition swept up millions of people researching electric vehicles out of curiosity, passengers riding in EVs, and even children whose phones pinged EV content. The surveillance dragnet operated without public notification or individual consent throughout its entire two-year run.

The Government’s Justification Falls Flat

Officials claim they needed this data to evaluate EV uptake patterns, overnight parking habits, and trip distributions to inform policy decisions. The DfT characterized the program as legitimate research to support the UK’s net-zero emissions goals and 2035 deadline for phasing out new petrol and diesel vehicle sales. Yet the government already collects extensive transportation data through vehicle registrations, MOT records, and congestion charging systems. This mobile surveillance added a layer of personal behavior tracking that went far beyond what vehicle ownership data could reveal, essentially profiling citizens based on their digital curiosity about emerging technology.

Follow the Money and the Motive

The £602,000 project funding came from the Evaluation Accelerator Fund as fuel duty revenues declined with rising EV adoption. Traditional petrol and diesel taxes generate billions annually for road maintenance and transport infrastructure. Electric vehicles escape fuel duty entirely, creating a revenue crisis the government must solve. Conservative officials explored pay-per-mile taxation schemes during this period, eventually implementing MOT-based road pricing in 2025. The surveillance project concluded in April 2024, perfectly positioned to inform the new tax structure that conveniently launched shortly after tracking ended.

Privacy Theater and Legal Loopholes

O2 defended the data handover as entirely lawful under the Data Protection Act 2018 and UK GDPR, insisting the information was anonymized and aggregated to show crowd patterns rather than individual behavior. That legalistic defense ignores the fundamental privacy violation of secretly monitoring millions of citizens’ browsing habits and movements. Big Brother Watch spokesperson Jake Hurfurt called the revelation shocking, noting that mobile data handovers to government agencies for vehicle research represent an unexpected expansion of surveillance capabilities. Sir David Davis, a Conservative MP and longtime privacy advocate, warned that citizens cannot trust the state with such data, which creates opportunities for policy discrimination against specific groups.

Political Blame Game Misses the Point

The Labour government, which took power shortly after the surveillance project ended, quickly distanced itself by characterizing the scheme as the previous Conservative administration’s “bizarre nanny state” overreach. Shadow Transport Secretary Richard Holden fired back, accusing Labour of using the collected intelligence to implement pay-per-mile tracking of EV owners. Both parties engaged in predictable finger-pointing while avoiding the core issue that government surveillance of lawful citizen behavior represents a dangerous precedent regardless of which party holds power. The civil service bureaucrats who designed and executed this program remain unnamed and unaccountable.

Trust Evaporates at Critical Moment

The surveillance revelation struck just as the UK desperately needs public buy-in for its EV transition strategy. Ginny Buckley, founder of Electrifying.com, characterized the program as Big Brother tactics that breach public trust precisely when government asks citizens to invest thousands in new vehicle technology. EV adoption already lags official targets due to charging infrastructure gaps, range anxiety, and higher purchase prices compared to conventional vehicles. Adding surveillance concerns and suspicions about future taxation creates another barrier discouraging mainstream consumers from making the switch. The DfT’s own report acknowledged significant data limitations, admitting it could not track actual charging behavior or travel times, raising questions about whether this invasive program generated useful policy insights worth the privacy cost.

Surveillance Creep Accelerates

This mobile tracking scheme follows a familiar pattern where governments justify expanded surveillance for limited purposes, then normalize the practice for broader application. COVID-19 mobility tracking established precedents for telecom companies providing movement data to government agencies under public health justifications. Law enforcement routinely obtains mobile location data for criminal investigations. The DfT surveillance represents something qualitatively different: tracking lawful citizen behavior to profile personal choices and inform taxation policy. That crosses a line from security-justified surveillance into using digital tracking as a policy research tool, opening doors for future expansions targeting other consumer decisions governments want to influence or tax.
