Cyber-attack
Kensington and Chelsea Council is addressing a 40% rise in complaints, partly attributed to a November 2025 cyber-attack that disrupted its systems.
Kensington and Chelsea Council is currently dealing with a 40% increase in complaints for 2025/26, with a report attributing this rise, in part, to a major cyber-attack in November 2025. The cyber incident, a malicious attempt to disrupt or gain unauthorised access to computer systems, disrupted Council systems, leading to delays in service delivery and a backlog of cases, according to the annual complaints report for 2025/26.
The annual complaints report for 2025/26 also noted that accepted complaints at Kensington and Chelsea Council increased by 22% to 2,168 during this period. The ongoing impact of the November 2025 cyber-attack continues to be a factor in the council's operations.
