'My whole life wiped from the record': Londoners speak out as duplicate image errors erase years of council housing applications

Hundreds of Londoners on social housing waiting lists say they have lost years of accumulated priority points after a technical fault caused local councils to flag their applications as duplicates, automatically removing scanned documents and, in some cases, closing cases entirely. The problem, which has surfaced across at least four London boroughs since early 2025, is forcing families to resubmit medical letters, proof-of-address histories and tenancy agreements that took years to gather.

The issue matters now because it is landing at the worst possible moment. The Labour government's ongoing planning reform push — centred on the Housing and Planning Reform Bill currently before Parliament — has directed renewed public attention to social housing allocation. Sadiq Khan's City Hall has pledged to accelerate affordable housing delivery across London, yet campaigners argue that administrative failures on this scale undermine any gains made on the supply side before they reach the people who need them most.

What the fault looks like on the ground

In Hackney, residents connected to the Hackney Housing Action group describe receiving automated letters in late 2025 informing them their applications had been merged with a duplicate record. The letters offered a 28-day window to appeal — a period several residents say they only discovered after it had already closed. One family in Stoke Newington, who declined to be named for fear of jeopardising their case, described submitting a fresh bundle of 47 pages of supporting documents for the third time in eighteen months.

In Tower Hamlets, the Bromley-by-Bow Centre — a community organisation on St Leonard's Street that works with low-income households — has been fielding calls from residents confused about why their 'reasonable preference' medical status had been stripped from their file without explanation. Staff there have been helping people reconstruct document trails, a process that can take weeks when GP surgeries and employers are slow to reissue paperwork.

Southwark and Newham have also seen complaints logged through the Housing Ombudsman Service. The Ombudsman's most recent annual report, published in 2025, recorded a 21 percent year-on-year rise in complaints related to records management and document handling across English social landlords — context that suggests London's experience is part of a wider pattern rather than an isolated glitch.

The human cost of a database error

For applicants who have spent years accumulating priority bandings, the stakes are high. Under the common allocation framework used by most London boroughs, a single additional year of qualifying need can move a household dozens of places up a list. Losing documented medical evidence or proof of overcrowding — the two most common categories affected — can wipe that advantage entirely.

The Chartered Institute of Housing estimates that around 160,000 households are on waiting lists across London at any given point. Even a fraction of those affected by document loss creates a significant administrative backlog, and housing advisers at centres including the Bow Neighbourhood Advice Centre on Addington Road say appointment slots for emergency document support are now booked four to six weeks ahead.

Borough councils have pointed to a software migration undertaken by several local authorities between 2024 and 2025 as the likely origin of the duplicate-flagging fault. No single supplier has been publicly identified, and none of the councils contacted for this article issued a statement by publication time.

For those caught in the system, the immediate practical advice from housing solicitors is consistent: request a Subject Access Request from your council under UK GDPR within 30 days of receiving any duplicate notification, as this forces the authority to produce every document it holds on your case. Keep physical copies of every submission. If the 28-day appeal window has passed, a formal complaint to the Housing Ombudsman Service — reachable at housing-ombudsman.org.uk — can still trigger a review, though current processing times run to approximately four months. The Local Government and Social Care Ombudsman handles cases where the council itself, rather than a registered provider, manages the list.

What is clear is that for families already stretched thin, rebuilding an application from scratch is not a bureaucratic inconvenience. It is, as one Stoke Newington resident put it plainly to a housing adviser this spring, starting over.
