UK third quarter 2025

UK composite insurance rate change 

UK property

UK property insurance rates decline

Property rates decreased 7%, compared to a 6% decline in the second quarter.

  • Levels of competition remained high, as insurers typically sought both new business and growth with existing clients.
  • Significant capacity was available, and insurers generally offered large limits, including in challenging industry segments.
  • Comprehensive risk management, clearly communicated, was instrumental in securing favorable terms.
  • Incumbent insurers often accepted rate reductions to retain business.
  • Long-term agreements (LTAs) with multi-year rate reductions were widely available.
  • Claims activity remained generally low; leading in some cases to insurers offering wider coverage options to attract new business.

UK casualty

Casualty rates flat, auto liability increases 

Casualty insurance rates were flat; excluding motor liability, casualty rates decreased 4%.

  • Overall casualty rates, excluding motor liability, continued to decline, especially when marketing multiple lines of business.
    • Clients with losses or large US exposure faced rate increases and capacity reductions.
  • Auto/motor liability rates increased, driven in part by increasing vehicle complexity and alternative fuel types bringing claims challenges.
    • Advanced sensors and diverse materials complicate underwriting and claims; electric vehicle (EV) battery damage often leads to total losses; batteries typically cost £8,000 to £12,000 to replace.
    • Since 2022, cost increases have been experienced in repair and parts, labor, theft, and reinsurance.

UK financial and professional lines

Financial and professional lines rates decline

Financial and professional lines rates declined 8%.

  • Directors and officers liability (D&O) rates declined 10%, driven by ample capacity. However, many insurers started to reject business based on pricing.
  • Financial institutions (FI) rates declined 7%, driven by significant available capacity.
  • Crime insurance rates declined 2%.

Cyber insurance rates decline for seventh consecutive quarter

Cyber insurance rates decreased by 11%.

  • Claim notifications spiked in the second quarter, with increased severity observed in the first half of 2025.
  • Clients generally increased limits at renewal.
  • Major UK cyberattacks have driven new buyers to enter the market, raising overall demand.
