'My gran's face, gone': Londoners speak out as duplicate image replacement strips family photos from council databases

A Peckham mother of three discovered last month that a photograph she had submitted to Southwark Council's housing portal — a scan of her late grandmother standing outside the family's former home in Lagos — had been silently replaced by a stock image of a generic document icon. The original file was gone. No notification had been sent. No backup existed on her end. The council's automated deduplication system had flagged the image as a duplicate of another resident's file and overwritten it.

She is not alone. Across London, residents who interact with local authority digital services are reporting a quiet but distressing phenomenon: automated duplicate-image-replacement protocols, built into housing, benefits and social care platforms to reduce storage costs and prevent redundant uploads, are erasing personal photographs, identity documents and case-related images — sometimes without any audit trail showing what was deleted or why.

Why this is happening now

The timing is not coincidental. Since January 2026, at least fourteen London boroughs have migrated case management systems onto a shared cloud infrastructure procured through the London Office of Technology and Innovation, known as LOTI, as part of a broader push to cut administrative overheads. Deduplication algorithms are a standard feature of these platforms, designed to prevent residents from uploading the same utility bill twice. But residents and housing caseworkers say the logic is being applied too broadly — matching images by file size or pixel dimensions rather than content — and that personal photographs are collateral damage.

Hackney Council's housing team confirmed in a written response to residents in May 2026 that its new platform uses automated image hashing to identify duplicate uploads. The response, shared with The Daily London by a resident who received it, did not specify how many files had been affected or whether deleted images could be recovered. Hackney Council had not responded to a request for comment by time of publication.

Tower Hamlets residents have raised similar concerns through the borough's formal complaints process. A community advice session held at the Whitechapel Ideas Store on Commercial Road on 19 June drew roughly forty attendees, many of them elderly or from non-English-speaking households, who said they had lost proof-of-address images, tenancy photographs and, in several cases, personal pictures accidentally uploaded alongside official documents.

What residents are losing — and what it costs to replace it

The practical consequences extend beyond sentiment. Under the Renters' Rights Act, which took full effect in April 2026, tenants in dispute with landlords must be able to produce timestamped photographic evidence of property condition at the point of application. If those images have been overwritten inside a council portal, residents face the burden and cost of gathering fresh documentation — or losing their case entirely.

At Lewisham's CAB-affiliated advice service on Rushey Green, caseworkers say they have seen a rise in requests for help reconstructing digital evidence files since February. Re-obtaining a certified copy of an identity document through the Passport Office or DVLA currently costs between £11 and £85 depending on the document type and processing speed. For a household already on housing benefit, that is not a trivial sum.

Older residents appear disproportionately affected. Digital literacy programmes run by Age UK London, which operates across thirty-two boroughs, report that many older clients do not retain local copies of files after uploading them, trusting council systems to act as a de facto archive. When those files vanish, there is often no route to recovery.

Residents who believe their images have been affected should submit a Subject Access Request under the UK GDPR directly to the relevant borough's data protection officer — councils are legally required to respond within one calendar month. LOTI has indicated it is reviewing deduplication parameters across shared platforms, though no firm timetable has been published. In the meantime, housing advisers recommend keeping local copies of every document uploaded to any council portal, stored either on a personal device or through a free cloud service such as Google Drive or Microsoft OneDrive, before submitting.
