The UK’s Housing Ombudsman Service has temporarily suspended its online complaint submission system following a cybersecurity incident involving an external technology provider. The disruption has raised concerns about the potential exposure of sensitive information belonging to social housing residents.
The organization confirmed the incident on October 13, 2026, explaining that its case management platform had been affected by a security problem at a third-party supplier. The system is used to manage complaints and disputes between residents and social housing providers across England.
According to the Housing Ombudsman, the incident has been contained, but investigators are still working with the technology supplier to determine what happened and whether any personal information was compromised.
The organization has not confirmed a data breach or disclosed how the security incident occurred. It also has not identified the affected supplier or provided an estimated timeline for restoring normal services.
The Housing Ombudsman is an independent public body responsible for investigating complaints involving social landlords, including housing associations and local authority landlords. Its work covers issues such as property repairs, maintenance failures, housing conditions and landlords’ handling of complaints.
Because these investigations can involve personal circumstances, correspondence and housing-related records, unauthorized access to the case management platform could potentially expose sensitive information. However, there is currently no evidence publicly confirming that attackers accessed or stole such records.
The service has reported the incident to the UK’s Information Commissioner’s Office (ICO), the regulator responsible for overseeing compliance with data protection legislation.
While the affected platform remains unavailable, residents cannot submit new complaints through the usual online process. The Housing Ombudsman has advised anyone needing assistance to contact its staff by telephone or email instead.
Officials have also warned residents to remain alert to suspicious communications, particularly unexpected messages requesting personal information. Such precautions are intended to reduce the risk of fraud while investigators determine whether any data was exposed.
Individuals with concerns about their information can contact the organization’s Data Protection Officer at DPO@housing-ombudsman.org.uk.
