What Jardine Lloyd Thompson Group does

Jardine Lloyd Thompson Group (JLT) was a UK-headquartered insurance broker, risk management consultancy, and employee benefits advisor serving enterprise clients across multiple industries and geographies. Founded in the late 1980s (firmographics list 1997; company history 1987) and historically listed on the London Stock Exchange under ticker JLT, the firm built a specialist reputation in complex insurance intermediation, multinational client placement, and corporate benefits consulting. JLT generated revenue through professional services engagements — broker commissions, consulting fees, and risk advisory mandates — delivered via enterprise field sales teams across the UK, Europe, and select international markets. Its service portfolio spanned property, casualty, financial and professional liability, political risk, trade credit, cyber risk, climate and sustainability advisory, captive insurance, and alternative risk transfer, alongside employee health, wellness, annuity, and investment services.

In 2012, JLT acquired Alexander Forbes Consultants & Actuaries Limited (AFCA) for £17 million, expanding its UK employee benefits division to approximately 25% of group revenues and adding 300+ employees across six UK offices. Through a sustained acquisition program between 2010 and 2018, JLT added specialty capabilities including Towers Watson's reinsurance brokerage business ($250 million in 2013), StoneHill Reinsurance Partners, Olsa Re, Hayward Aviation, Lambert Brothers Holdings, and others. Its technology stack centered on proprietary risk analytics tools inherited or aligned with the Marsh platform — most notably the Global Insurance Market Index (GIMI) and the Cross-Check aviation report — leveraging data and analytics to advise clients on commercial insurance rate movements and risk transfer strategy.

In 2019, Marsh & McLennan Companies acquired JLT for approximately $5.6 billion, taking it private and ending its independent listing. Post-acquisition, JLT operates as a wholly-owned subsidiary within Marsh & McLennan's portfolio of operating companies (Marsh, Guy Carpenter, Mercer, Oliver Wyman), with the Employee Benefits division integrated into Marsh's broader UK franchise. The financials table supplied contains apparent formatting anomalies (figures in the trillions) and does not align with JLT's standalone scale; standalone public reporting prior to 2019 indicated multi-billion-dollar annual revenue supported by 10,000+ employees globally.
