Government plan proposes large-scale contact tracing network using live mobility data and artificial intelligence.

The United Kingdom’s newly released pandemic preparedness strategy outlines plans for a nationwide contact tracing system that would rely on real-time location data and artificial intelligence, with development expected to involve major technology companies.

The proposal, published by the Department of Health and Social Care, frames future pandemics as inevitable and calls for expanded infrastructure to respond to outbreaks. Alongside provisions for stockpiling protective equipment, introducing emergency legal powers, and establishing a biosecurity research center in Essex, the strategy places significant emphasis on building a digital tracking system capable of monitoring population movement at scale.

According to the official strategy document, the United Kingdom Health Security Agency will oversee the development of a contact tracing platform designed to use “live location data” combined with artificial intelligence to enable rapid detection and notification during future public health emergencies. The system is expected to be operational by 2030.

The plan states that officials intend to “explore options to work with ‘big tech’” to support the system’s development, though it does not identify specific companies or outline how data-sharing arrangements would function. Details regarding how collected data would be stored, managed, or handled after a pandemic period are also not specified.

The proposal follows earlier disclosures that government-linked research groups had previously used mobile phone data to monitor population movement during the COVID-19 response. A 2021 report revealed that researchers associated with the Scientific Pandemic Influenza Group on Behaviors analyzed mobility data from a portion of the population without public notification.

According to that report, researchers examined anonymized cell phone data to track the movements of thousands of vaccinated individuals, analyzing patterns such as travel distances, visits to businesses, and post-vaccination behavior. The data was derived from call data records and used to study behavioral responses following vaccination.

The disclosure prompted concerns from privacy advocacy groups. A spokesperson for the organization Big Brother Watch stated that citizens would be “disturbed to discover they were unwittingly tracked and subjected to behavioral analysis via their phones.” The spokesperson added, “No one expects that by going to get a vaccine they will be tracked and monitored by their own Government,” and warned that such practices could affect public confidence in medical privacy.

Government officials responded by emphasizing that the data used in the research was anonymized and collected at the level of cell towers rather than individual devices. A spokesperson said “the mobile phone location data used is GDPR-compliant and has been provided from a company that collected, cleaned, and anonymized the data” and that “the data is at cell tower rather than individual level and the researchers were granted access to the dataset under a research contract with ethical approval provided to the researchers from the University of Oxford, working on behalf of SPI-B.”

The new strategy formalizes the potential use of similar data-driven approaches, transitioning from previously disclosed research practices to a proposed permanent capability embedded within government systems. The plan’s reliance on aggregated mobility data and private-sector collaboration reflects a continuation of methods explored during the pandemic, now incorporated into long-term preparedness planning.

During earlier stages of the COVID-19 response, the UK government attempted to deploy a centralized contact tracing application through NHSX. That system faced technical and privacy-related challenges and ultimately failed to operate effectively, in part due to conflicts with platform restrictions imposed by major mobile operating systems.

The updated strategy signals a shift toward developing a more scalable and integrated approach to contact tracing, with an emphasis on speed, automation, and broader data inputs. Officials have indicated that further exploration and development will continue in the coming years as part of the government’s wider pandemic readiness efforts.
