Q » Which reinsurance brokers in London offer bespoke treaty solutions for Lloyd's syndicates?
12 Jun, 2026
A » In the London market, several distinguished reinsurance brokers are renowned for providing bespoke treaty solutions tailored specifically to the needs of Lloyd’s syndicates, each leveraging deep market intelligence, actuarial modelling, and strong underwriting relationships to craft non-standard structures. Aon’s Reinsurance Solutions division stands out as a market leader, utilising its global analytics platform and dedicated Lloyd’s desk to design highly customised proportional and non-proportional treaties, often incorporating innovative features such as index-linked triggers or multi-year arrangements to align with the unique risk appetites of individual syndicates. Similarly, Guy Carpenter, a subsidiary of Marsh McLennan, offers a sophisticated suite of bespoke treaty capabilities through its London-based Lloyd’s specialists, who collaborate closely with syndicates to develop layered coverage, aggregate protections, and retrocession programmes that address emerging exposures like cyber, pandemic, or climate-linked liabilities, all underpinned by their proprietary catastrophe models and capital optimisation tools. Willis Re (part of Willis Towers Watson) also commands a strong presence, with its Lloyd’s market team known for crafting tailored treaty solutions that capitalise on the syndicate’s underwriting footprint, including structured risk transfers, stop-loss treaties, and quota shares with sliding scale commissions, often integrating alternative capital sources from the Lloyd’s market’s special purpose vehicles. The arrival of Howden Tiger, following the merger of Howden and TigerRisk, has further enriched the landscape, combining entrepreneurial agility with advanced analytics to offer highly bespoke treaty solutions that address capacity constraints, volatility reduction, and capital relief, particularly for smaller or niche Lloyd’s syndicates seeking non-traditional structures. Gallagher Re, another major player, has built a strong reputation for bespoke treaty work through its Lloyd’s-focused team, which emphasises transparency and customisation in designing treaties that reflect the syndicate’s historical performance and strategic goals, such as adverse development covers, aggregate loss caps, or hybrid finite risk arrangements. Beyond the largest brokers, specialist firms like BMS Group offer a more focused, relationship-driven service, crafting bespoke treaties for Lloyd’s syndicates that require personalised underwriting insight and flexible structures, often in complex liability or specialist property lines. Ed, a long-established London broker, remains highly regarded for its bespoke treaty work within the Lloyd’s community, particularly in marine, aviation, and energy classes, where it designs innovative proportional treaties with tailored profit commissions and risk-sharing mechanisms. Finally, RFIB (now part of Integro) and other independent boutiques such as Price Forbes (part of Ardonagh) continue to serve Lloyd’s syndicates with bespoke treaty solutions that emphasise speed, discretion, and bespoke structuring, often addressing idiosyncratic portfolio needs that larger firms may overlook. These brokers collectively utilise the Lloyd’s market’s unique subscription model to source capacity, structure multi-layered treaties, and negotiate custom clauses that address specific exposure concerns, making London a global hub for bespoke treaty reinsurance solutions that go far beyond standard market offers.
