Leeds Council's Duplicate Image Problem: What Changed This Week

Leeds City Council confirmed this week that it has begun a structured audit of its online planning portal after staff identified a significant volume of duplicate images clogging the system — identical photographs, scanned documents and site survey files uploaded multiple times across hundreds of active and historic planning applications. The audit, which started in the first week of July 2026, covers records dating back to at least 2009, when the council migrated its paper files to its first digital planning database.

The problem matters now because the council is mid-way through a major upgrade of its public-facing planning portal, part of a wider digital transformation programme budgeted at roughly £4.2 million across all council departments for the 2025-26 financial year. Carrying duplicate content into the new system would inflate storage costs, slow search speeds for applicants and residents, and potentially present contradictory documents to planning officers making decisions on live applications.

Where the Problem Is Most Acute

Two areas of the city have generated the highest volume of problematic records, according to the council's internal communications reviewed by The Daily Leeds. The Kirkgate Market conservation zone in the city centre and the Meanwood Road corridor — both subject to sustained development pressure over the past decade — account for a disproportionate share of re-uploaded site photographs, some appearing four or five times within a single application file. Kirkgate Market alone has been the subject of more than 60 planning applications since 2015, many involving heritage impact assessments that required extensive photographic documentation.

Leeds Civic Trust, which regularly engages with the planning system on behalf of residents concerned about heritage assets, has flagged the issue separately in correspondence with the council's development management team. The organisation noted that searching for photographic evidence relating to listed buildings in areas like Chapel Allerton and Horsforth had become unreliable, with duplicate images sometimes displaying different file metadata, making it difficult to establish which version was the authoritative submission.

The West Yorkshire Combined Authority's digital services unit, based at Wellington House in Leeds city centre, is also involved. The Combined Authority runs shared data infrastructure for the five West Yorkshire councils, and any fix applied to Leeds's records will need to be compatible with the wider regional system before the planned regional planning data hub goes live — currently scheduled for early 2027.

What the Audit Involves and What Comes Next

The audit team — drawn from the council's ICT directorate and planning support staff based at Merrion House on Merrion Way — is using automated deduplication software to flag matches above a 95 percent similarity threshold. Human reviewers then confirm whether flagged files are true duplicates or legitimate revisions. The council expects the first phase of the audit, covering applications submitted between 2009 and 2018, to be complete by September 2026.

For residents and developers with live applications, the practical advice from the council's planning helpline is to continue uploading documents in the normal way and not to re-submit files already confirmed as received. Anyone who has submitted supporting images in the past six months and is uncertain whether their documents are correctly filed should contact the development management team directly via the Merrion House public counter, which is open Tuesday to Thursday.

The council has not yet said whether any planning decisions made in recent years will need to be re-examined as a result of the duplicate records issue. That question is likely to be central to the next meeting of the council's Plans Panel, which sits monthly and is attended by ward councillors from across the city. The panel's July sitting is scheduled for 22 July 2026 at Civic Hall on Calverley Street.

For Leeds's broader digital ambitions — the council published a Digital Leeds Strategy in 2024 pledging fully paperless planning processes within five years — getting the archive clean before the new portal launches is not optional. A cluttered, unreliable record system would undermine the very efficiency gains the programme is meant to deliver.
