Thousands of Londoners are caught in a bureaucratic tangle after a growing number of councils have acknowledged holding duplicate image files — passport scans, tenancy photos, medical letters — filed under the wrong names or cross-linked to unrelated accounts. The problem, which affects at least six of London's 32 boroughs according to local authority internal reviews seen by The Daily London, is triggering delays in housing allocations, Universal Credit assessments, and GP referral processes that depend on verified identity documents.
The timing matters. The Labour government has placed digital public-sector reform at the centre of its agenda since taking office, and Keir Starmer's Cabinet Office has pushed local authorities to migrate legacy paper records onto unified digital platforms ahead of a 2027 compliance deadline. That migration, while broadly supported by councils, has exposed long-standing weaknesses in how image assets are stored, tagged, and deduplicated across incompatible legacy systems.
What Residents in Hackney and Hammersmith Are Dealing With
In Hackney, the Pembury Estate Residents' Association has been fielding complaints since at least January 2026 from tenants who say their housing applications stalled after council staff could not verify submitted photographs against records on file. One long-term resident told The Daily London her application to transfer to a ground-floor flat — submitted in October 2025 on medical grounds — was put on hold for 14 weeks while Hackney Council's housing team resolved a database conflict involving her scanned documents.
In Hammersmith, the advice service at the Shepherd's Bush Community Hub on Uxbridge Road has seen a noticeable rise in walk-in queries related to document mismatches since February, according to a caseworker there who asked not to be named because she was not authorised to speak publicly. She said the most common scenario involves a scanned image — typically a tenancy agreement or photo ID — appearing under a different resident's record number, causing automated eligibility checks to fail before a human reviewer ever sees the file.
Similar reports have come from residents near Lewisham Gateway and in parts of Tower Hamlets served by the Poplar HARCA housing association. In each case, the underlying complaint is the same: a clerical error embedded in a digital system is harder to correct than a paper one, because it propagates across linked databases before anyone notices.
The Data Problem and What Councils Are Doing About It
The scale of the issue is difficult to pin down precisely because councils are not required to publish data on internal image-management errors. However, a February 2026 report from the Local Government Association — a body representing councils across England and Wales — noted that roughly 40 per cent of surveyed authorities had identified duplicate or mis-tagged digital records during recent system migrations. The LGA report did not break the figure down by authority or region.
The Mayor's office confirmed to The Daily London that Sadiq Khan's team is in contact with Transport for London's digital infrastructure unit and the Greater London Authority's data team to understand whether any cross-authority records — such as those used in the Homes for Londoners scheme — are affected. A formal review is expected to be complete by September 2026.
For affected residents, the practical advice from digital rights groups including the charity Citizen Tech UK, which operates a helpline from offices in Brixton, is to request a Subject Access Request under UK GDPR from their council as a first step. This legally compels the authority to provide all records held under a resident's name within 30 days, allowing individuals to identify and flag incorrect image associations themselves. Citizen Tech UK says the process costs nothing and can be initiated online or by post.
Councils including Hackney and Lewisham have both confirmed to this newspaper that they have dedicated staff handling SAR backlogs, though waiting times have lengthened. Hackney's published response standard is 28 days; the council's most recent quarterly report, covering January to March 2026, showed an average processing time of 34 days.
With the government's 2027 digital compliance deadline approaching, campaigners say councils need to prioritise deduplication audits before migrating further records — not after the fact, when the harm is already done.
