Cyber insurance is a specialised form of business cover designed to help organisations manage the financial impact of cyberattacks, data breaches and related operational disruptions. While many businesses assume their general insurance policies provide sufficient protection, cyber incidents often create costs that fall outside standard cover, including technical investigations, legal advice and regulatory penalties.
The January 2026 cyberattack on a West London council
The growing scale of cyber risk was highlighted in January 2026, when a cyberattack on the Kensington and Chelsea council disrupted operations. The incident exposed sensitive personal information belonging to hundreds of thousands of residents and caused widespread service outages. Essential systems for payments and records access were unavailable for several days, demonstrating how interconnected digital systems can amplify the impact of a single breach. The attack also prompted a national review of cybersecurity practices across local authorities, underlining the broader implications of such events.
Cyber insurance policies are designed to respond to incidents like these by addressing several key areas. They typically cover incident response costs, including forensic specialists who investigate how the breach occurred and legal advisers who help organisations meet regulatory requirements. Policies may also cover the cost of notifying affected individuals, as required under UK data protection laws, and managing the reputational impact of an incident.
In addition, cyber insurance can help offset business interruption losses resulting from system downtime. Some policies also include support for public relations efforts or assistance with ransomware incidents, such as access to specialist negotiators.
Coverage limits and exclusions vary widely, making it important for businesses to understand the specifics of any policy they consider.
Measures that all businesses should have in place
Cyber incidents were ranked as the top global business risk by the 2026 Allianz risk barometer. This includes small and medium-sized enterprises that are facing increased exposure from sophisticated, AI-driven attacks. While insurance can provide financial support, basic risk management measures remain important. These include multi-factor authentication, regular data backups and staff phishing awareness training.
