More than 44,000 people have filed formal Article 21 objections demanding NHS England stop sharing their health data with Palantir, the US firm whose consortium runs the health service's national data platform. The right to object is not absolute. NHS England can refuse where it can show compelling grounds to continue, under guidance from the Information Commissioner's Office.
A hospital data platform is meant to work like plumbing: largely invisible until questions arise about who can reach the pipes. Those questions have now pushed more than 44,000 patients to file formal objections, even as the £330m, seven-year contract heads towards a break clause in February 2027.
According to The Guardian's reporting, the decision will ultimately fall to Prime Minister Andy Burnham. The department runs day to day under Health Secretary Yvette Cooper, who took up the post on 20 July 2026, the same day Burnham became prime minister.
BMJ Finds Only 85 of 139 'Live' Trusts are Actually Using It
NHS England has called 139 trusts 'live' with the Federated Data Platform and, officials have told Parliament, pointed to that figure as a sign of its popularity. A BMJ investigation found that only 85 of those 139 trusts recorded any user activity, across the eight FDP apps for which NHS England held FOI data, in the year to mid-2026.
NHS England reports benefits including more than 110,000 additional operations and faster cancer-diagnosis times, and credits the platform for them. It has told the Office for Statistics Regulation that it cannot draw conclusions about cause and effect, because other variables were not controlled for. An independent academic evaluation is still under way.
NHS England Admits Documentation Gap Over Three Engineers' Access
NHS England's own documentation initially said only NHS staff could see identifiable patient data within part of the platform. NHS England has since acknowledged that description did not fully reflect operational arrangements, and that some suppliers do have controlled access.
Three Palantir engineers hold administrative, year-round access to the platform's National Data Integration Tenant, providing technical support every day of the year. A further 33 supplier engineers held more limited, project-specific access as of 15 June 2026.
NHS England says all suppliers act strictly as processors under its instruction. Access is role-based, time-limited and vetted, and administrative access is reverified every three months and audited monthly.
Health Committee Tells Ministers to Prepare Alternative by 2027
The House of Commons Health and Social Care Committee, chaired by Layla Moran MP, has told ministers to start preparing an alternative before the February 2027 break clause arrives.
The committee's letter cites what it calls 'serious mistrust' of Palantir among the public as a risk to the NHS's wider digital ambitions.
What Tech Workers and Privacy Users are Saying Online
Two Reddit threads capture a split reaction. In r/dataengineering, commenters questioned the technical case for Palantir.
One pointed to what they described as an earlier, roughly £600m NHS England data project that was abandoned, a recollection, not a cited source. Others argued an open Spark and Delta Lake stack would have avoided vendor lock-in.
In r/privacy, users focused on the scale of access Palantir has been granted, rather than the underlying technology.
Whichever way the government decides before February 2027, both arguments will be read as having won.
