Coventry's Duplicate Image Problem: The Key Decisions That Will Shape the City's Visual Record

Coventry City Council's heritage and planning departments are sitting on a growing problem: thousands of duplicate and mislabelled images spread across multiple digital archive systems, with no single agreed process for resolving the mess. Officers have identified the issue as a priority ahead of a scheduled audit this autumn, but decisions about staffing, software and legal ownership of the affected files remain unresolved.

The problem matters now because the council is mid-way through two major regeneration schemes — the Belgrade Plaza expansion and the ongoing Friargate business district development along Station Avenue — both of which require clean, legally defensible visual records for planning applications, public consultations and future appeals. Duplicated or misattributed images in those files create risk at every stage of the process, from initial submission to any subsequent legal challenge.

What the Archive Actually Contains

The Coventry History Centre on Bayley Lane, which holds the city's principal photographic collection, began a partial digitisation programme in 2019. That project produced a searchable database but also ingested large batches of images without rigorous deduplication checks, according to documents tabled at the council's Economy and Culture scrutiny panel in March 2026. The result is an index where the same photograph — sometimes of the same street corner on Broadgate or the same elevation of the Herbert Art Gallery — can appear under three or four separate reference numbers, each carrying different metadata.

Planning files held separately by the council's Development Management team compound the issue. Officers submitting supporting imagery for applications in areas such as Hillfields and Foleshill have on at least two documented occasions this year attached outdated site photographs, not realising newer images under different filenames referred to the same location. The council has not published a total count of affected records, but the scrutiny panel documents reference an internal estimate of more than 4,000 duplicate entries requiring manual review.

The financial picture is uncomfortable. A quote obtained by the council from a specialist digital asset management provider put the cost of a full automated deduplication exercise, followed by human verification, at between £85,000 and £120,000 depending on the scope agreed. That figure does not include the cost of any new licensing for replacement asset management software, which officers flagged could add a further £30,000 to £40,000 annually.

The Decisions Officers Cannot Avoid

Three choices are now sitting in front of senior officers and elected members, and none of them is straightforward.

First, the council must decide whether to run deduplication in-house using existing IT staff or procure an external contractor. The in-house route is cheaper upfront but adds workload to a digital team already stretched across the Coventry Digital Strategy commitments running to 2027. External procurement is faster but triggers a formal tendering process that, under current thresholds, cannot be shortcut.

Second, officers must settle the question of image ownership before any records are deleted or merged. Some photographs in the Coventry History Centre collection were donated by local community groups, including the Coventry Society and former residents' associations in Earlsdon and Cheylesmore. Deleting a duplicate without establishing which version carries the correct provenance data could mean losing the authoritative copy entirely.

Third, and most politically sensitive, the council must determine who bears accountability when a duplicate image has already been used in a submitted planning document. Legal officers are reviewing at least two live cases where this question has been raised.

The scrutiny panel is expected to receive an updated officer report in September 2026, ahead of the full audit beginning in October. If members approve a preferred route at the September meeting, procurement or in-house mobilisation would realistically begin in November at the earliest, meaning the problem will not be resolved before the end of the calendar year.

Community groups with donated material in the Coventry History Centre have been advised to contact the archive team on Bayley Lane directly if they wish to register an interest in the review process. The council's planning portal on the city website also allows applicants to flag image discrepancies in live applications, a function that officers say has been used only a handful of times since it was introduced in 2024.
