London Councils and Property Firms Race to Fix Duplicate Image Problem Plaguing Housing Listings This Week

Thousands of London property listings have been pulled or corrected this week after a widespread duplicate image fault caused the same photographs to appear across multiple unrelated addresses, misleading renters and buyers across the capital. The problem, which first surfaced at scale on Monday 29 June and accelerated through the holiday weekend, has affected listings on major portals including Rightmove and Zoopla, with estate agents from Hackney to Hammersmith reporting client complaints about photographs showing a Dalston studio flat paired with a description of a four-bedroom house in Dulwich.

The timing is acutely bad. London's rental market is already under severe strain, with average asking rents in the capital hitting £2,627 per month in June 2026 according to data from Dataloft. Prospective tenants — many of whom book viewings within hours of a listing going live — say they have wasted money on travel and time on properties that looked nothing like their photographs. At least one letting agent on Stoke Newington Church Street told The Daily London that three separate clients had turned up to viewings this week expecting a modern kitchen and found an unrenovated 1970s galley instead.

What Caused the Fault — and Who Is Fixing It

The root cause appears to be a bulk upload malfunction in an image-management middleware layer used by several London-based property software companies, including a platform called Jupix, which serves hundreds of independent estate agents across Greater London. When agencies processed large batches of new listings between 29 June and 1 July, image file identifiers were incorrectly mapped, causing the system to pull photographs from previously archived properties and attach them to newly created records. Jupix issued a technical advisory on Wednesday 2 July acknowledging the error and said a patch had been deployed by 18:00 that evening.

Rightmove confirmed on Thursday that it had identified roughly 4,200 affected listings across England and Wales, of which approximately 1,100 were London addresses. Zoopla said its own content moderation team had flagged 640 suspect London listings between Tuesday and Thursday morning alone. Both portals said automated image-fingerprinting tools were being run against their full databases to catch any remaining mismatches before the weekend rush of new listings, which typically peaks on Saturday mornings.

The Property Ombudsman, based in Salisbury but covering all London agents, confirmed on Friday it had received 47 formal complaints related to the issue in the past five days — more than the total duplicate-image complaints logged in all of 2025. Agents registered with the National Association of Estate Agents have been advised to manually audit any listing uploaded between 28 June and 2 July and to prioritise re-uploading photographs through their own direct portals rather than relying on third-party middleware until the patch has been fully stress-tested.

What Renters and Buyers Should Do Now

Consumer group Which? published guidance on Friday afternoon urging anyone who booked a London viewing this week and found a material discrepancy between images and reality to request a full refund of any holding deposit under the Tenant Fees Act 2019. The Act, which caps holding deposits at one week's rent, explicitly allows refunds where an agent has provided misleading information — a category solicitors say almost certainly applies here.

Sadiq Khan's office confirmed on Friday that the Greater London Authority's housing team had been in contact with both Rightmove and Jupix and was monitoring whether any affordable or council-adjacent listings managed through the GLA's own London Living Rent programme had been affected. So far, none of the 312 current London Living Rent listings appear to have been compromised, a spokesperson said.

For anyone currently searching for a property in London, the practical advice is blunt: cross-reference every listing against the agent's own website before booking, reverse image-search the main photograph to check for duplicates on other addresses, and do not hand over any payment before viewing. The portals say the bulk of affected listings will be corrected or removed by end of day Saturday 4 July, though agents say it may take until early next week before every mismatched image has been replaced.
