Insurance rates in the UK declined 8% in the first quarter, the ninth consecutive quarter of decline.

UK composite insurance rate change

UK property

UK property insurance rates decline

Property rates decreased 10%, the same as in the prior quarter.

Ample insurer capacity and high levels of competition remained, including for more challenging lines.
Insurers showed greater willingness for broader policy language, particularly for clients seen as demonstrating strong risk mitigation practices.
The stable claims environment supported insurer appetite to extend cover for clients with risks viewed as well-managed.
Underwriters focused on catastrophe exposures and site-specific vulnerabilities.
Cyber exclusions remained a point of negotiation.

UK casualty

Casualty rates decline in competitive market

Casualty insurance rates declined 3% overall; with a 6% decrease when excluding motor liability.

Insurer capacity remained ample, driving competition.
Long-term agreements, typically spanning two to three years, were often available.
Underwriters scrutinised motor liability clients for high-cost exposures, particularly those involving electric vehicle (EV) fleets, complex electronic repairs, parts shortages, and labour constraints.
Exposures involving per- and polyfluoroalkyl substances (PFAS) and pollution, frequently encountered exclusions or restrictive terms, particularly where insurers considered controls inadequate.
Emerging mobility trends, including short-term hire and alternative transportation options, as well as legislative changes, have added complexity to the risk landscape.

UK financial and professional lines

Financial and professional lines rates decline; underwriters scrutinise US exposure

Financial and professional lines rates declined 8%, compared to a 5% drop in the previous quarter.

Directors and officers liability (D&O), financial institutions (FI), and crime rates registered high single-digit decreases. Capacity across financial lines remained available.
Underwriters increased scrutiny of D&O submissions involving exposure to US securities, with attention given to governance practices, escalating claim costs, and litigation trends.
Crime coverage varied by insurer, with wording and scope typically influenced by an insurer’s evaluation of internal controls, detection mechanisms, and response protocols.
Appetite for FI and professional indemnity (PI) lines was primarily shaped by sector-specific exposures.

Cyber insurance rates decline, capacity increases

Cyber insurance rates decreased 8%, compared to 12% in the prior quarter.

Cyber insurance capacity and competition levels increased, with insurers seeking to differentiate themselves in areas including line size, wording, and attachment terms.
Cyber incidents increased, with a notable rise in extortion claims outside of traditional ransomware.
Cyber resilience and governance have become key agenda items for boards and risk managers.
