Commercial insurance rates in the UK fell 8% in the third quarter of 2026, matching the prior two quarters and extending a run of consecutive rate declines to 11, according to Marsh’s Global Insurance Market Index (GIMI) for Q3 2026. All major lines recorded net average decreases, supported by ample capacity, a quiet natural catastrophe season, and continued competition among incumbent insurers to retain business.
The sustained softening reflects broader global conditions. Global composite rates fell 5% in Q3 2026, the ninth consecutive quarterly decline, according to the same index, with property again driving the largest reductions. But the UK is moving faster than the global average, and the Q3 data shows the domestic market still has momentum.
Property rates fell 11% in Q3 2026, unchanged from the prior quarter. Capacity remained plentiful across most industry segments, including some that would have drawn more scrutiny in harder market conditions, with facilities playing a meaningful role in placement. Incumbent insurers sought significant rate reductions to retain clients, and long-term agreements were readily available, including meaningful reductions for those cancelling and rewriting existing deals.
That level of competition has shifted the dynamics of renewal preparation. Clear risk management documentation, early market access, and high-quality submissions continued to separate outcomes at the margin, even in a market where the general direction of pricing is downward. Underwriters also showed an increased willingness to broaden coverage to win new business, and cyber exclusion language was an active point of discussion.
One condition supported all of this: the absence of major risk losses in the UK during Q3 2026. A more active catastrophe season would have tested the durability of current pricing, and the relationship between catastrophe loss years and subsequent market hardening is well established. The current soft cycle was shaped in part by what happened in the years before it.
Casualty rates declined 3% overall in Q3 2026, with casualty excluding motor falling 5%, the fourth consecutive quarterly decline. Newer retail market entrants added appetite and flexibility, and strategic renewal approaches tended to produce the largest reductions.
Motor was the exception. Outcomes varied significantly by sector, ranging from rate increases of 5% to reductions of the same magnitude, depending on the account. Two cost pressures were consistent across motor lines: elevated repair inflation and labour costs, and the growing weight of electric vehicle (EV) claims, which continued to drive higher severity and longer repair times. Changing mobility patterns, including shifts in vehicle ownership, growth in short-term cover, and the rise of alternative transport, added new claims and legal considerations that underwriters are still working through.
For accounts with meaningful US casualty exposure, conditions tightened further. Some insurers reviewed deployed capacity and attachment points specifically for US-focused risks, a pattern consistent with the wider global casualty divergence driven by US litigation pressures that have kept casualty rates rising in the US even as they fall across every other major market.
Financial and professional lines rates fell 5% in Q3 2026, compared with a 4% decline in the prior quarter, continuing a run of rate reductions that began in the fourth quarter of 2022. Capacity remained available, supported by new entrants and managing general agents (MGAs) across most sub-lines.
Directors and officers (D&O) liability declines slowed, with pricing increasingly dependent on the policyholder’s domicile, public or private status, and industry sector rather than moving uniformly. Financial institutions broadly secured rate reductions, which Marsh expects to remain available for the foreseeable future.
Crime pricing continued to ease unless accounts had suffered material recent losses. One line being monitored carefully is financial institutions cover, where the potential liability impact of the UK motor finance commission case, which followed the Financial Conduct Authority’s review of historical discretionary commission arrangements and a contested Court of Appeal ruling, continues to be monitored for its effect on pricing.
Cyber rates fell 7% in Q3 2026, slightly faster than the 5% decline in the prior quarter, though the pace of reductions was more moderate than in earlier quarters. Incumbent insurers generally sought to retain clients, and the balance between price, continuity, and claims expertise remained a live consideration for buyers deciding whether to move at renewal. Strong renewal preparation continued to deliver better outcomes, Marsh noted, even in a market where buyers generally hold the advantage.
In Marsh’s global commentary accompanying the index, John Donnelly, president of global placement, noted that geopolitical uncertainty and economic concerns were leading many buyers to bank premium savings rather than reinvest them in coverage enhancements. The UK market, with rate reductions now running across eleven consecutive quarters, offers clear scope for buyers willing to look at structural improvements alongside savings, whether through broader coverage, reduced retentions, or long-term agreements that lock in current conditions.
