How Leeds Ended Up With Hundreds of Duplicate Images Cluttering Its Public Record: The Story So Far

Leeds City Council is sitting on a digital archive problem years in the making. Across multiple internal systems — including the council's planning portal, the Leeds Libraries digital collections platform, and the West Yorkshire Combined Authority's shared asset register — thousands of duplicate images have accumulated, some misfiled under wrong postcodes, others simply copied and re-uploaded by successive contractors working without a shared protocol. The problem has now reached a scale where a formal duplicate image replacement programme is under active consideration.

The timing matters. Leeds is midway through its City Centre Connectivity Strategy, a £1.6bn infrastructure programme stretching to 2030. Every planning application attached to that programme depends on accurate, non-redundant photographic documentation. When duplicate or mislabelled images enter the public record, they can delay decisions, confuse heritage assessments, and create legal exposure for the council during appeals. The issue is no longer a back-office nuisance — it touches live planning cases on streets including Kirkgate, Wellington Street, and the Aire Valley regeneration corridor.

Where the Problem Began

The roots go back to roughly 2014, when Leeds City Council began a push to digitise its estate and planning records following central government pressure to move local authorities onto cloud-based document management. The council adopted OpenText Content Suite as its document platform, but individual directorates — planning, highways, heritage — continued uploading images through their own legacy portals in parallel. By 2018, the Leeds Digital Festival was showcasing the city as a model of digital governance. Behind that public image, the duplicates were already piling up.

A secondary wave came during 2020 and 2021. Emergency planning applications related to COVID-19 business adaptations — pavement licensing on Briggate, temporary structures at the First Direct Arena forecourt, pop-up infrastructure across Headingley and Harehills — were processed under compressed timescales. Photographs were submitted by applicants, uploaded by planning officers, then sometimes re-uploaded after system migrations. Nobody had a mandate to audit what already existed before adding new files.

The West Yorkshire Combined Authority's merger of transport and economic development imagery into a single shared asset register in early 2023 added another layer of complexity. Images originally held by Metro, the regional transport body, and those from Leeds City Council's own highways teams ended up in the same repository with no deduplication step built into the migration process. Staff at the council's offices on Merrion House flagged the issue internally, but no dedicated resource was allocated at that point.

What the Evidence Shows

While the council has not published a full audit, procurement documents released under the Freedom of Information Act in March 2026 referenced a backlog of more than 40,000 unverified image records across the planning and asset management systems — a figure that officers described in the documents as a conservative estimate. The cost of manual review was quoted in the same documents at approximately £180 per working hour for specialist archival contractors, making a comprehensive hand-check prohibitively expensive without automated tooling.

The Leeds Civic Trust has raised concerns separately about heritage photograph records, particularly those relating to listed buildings in the Little Woodhouse conservation area and along the Meanwood Valley, where duplicate or outdated images have been cited in at least two planning objections lodged in 2025.

The council is expected to bring a proposal to its economy and infrastructure scrutiny board before the end of September 2026. Under one option being assessed, an automated image fingerprinting tool would be applied across all active repositories, flagging likely duplicates for officer review rather than deletion. A second option would involve outsourcing the deduplication work entirely to a specialist contractor under a framework already used by Bradford Council for a comparable exercise completed in late 2024.

For residents and community groups tracking planning applications in their neighbourhoods — whether in Armley, Chapel Allerton, or the city centre — the practical upshot is straightforward: before any replacement programme is complete, it is worth downloading and saving copies of photographic evidence submitted to the public planning portal, because image availability cannot currently be guaranteed once a case closes.
