About Tokio Marine Kiln

Tokio Marine Kiln, often shortened to TMK, is a specialist international insurer that operates in the Lloyd's and London Market. It says it has customers in over 170 countries and about 200 coverholders worldwide. Its 17 lines of business include accident and health, aviation, cyber, energy, fine art and specie, intellectual property, liability (outside the USA), life sciences, marine cargo, motor, political risk, political violence and terrorism, product recall, property, surety and technology errors and omissions.

The company says it wants to be a "Good Company", a great company to do business with and a great place to work. It describes an internal formula for its culture that combines traits that seem like opposites, such as tradition and innovation, and analytical skill and emotional intelligence. It says inclusion is one of its values and that a diverse talent pool is essential to innovation.

TMK is part of Tokio Marine Group, which it calls one of the world's largest insurance groups. It has operated in Asia-Pacific for 20 years. We did not find a founding date or a detailed history on the pages we read. Its site also has pages on its Brexit response and its corporate structure, which are worth reading to see how a London Market insurer is set up to serve clients in Europe and beyond.

Its London office is at 20 Fenchurch Street, EC3M 3BY. The website's People Finder lists over 200 individuals in London and Singapore across Claims, Delegated Authority, Distribution, Finance, Human Resources, Information Technology, PR and Marketing, and Underwriting. Examples include the Divisional Head of General Aviation and Aerospace and a Lead Cyber Analyst. We did not find a published UK headcount.

TMK says it is one of only two London Market insurers to receive the Gracechurch Service Quality Marque for both underwriting and claims in 2026, and that its claims team has won the claims award for ten years in a row. These are its own statements. It also became a founding partner of FemTick, an accreditation for organisations that support women's health, and it supports Great Britain Wheelchair Rugby. Roles at TMK include specialist underwriters, claims handlers, delegated authority staff who oversee coverholders, and cyber analysts. Its recent product news, such as an updated cyber wording that covers incidents affecting physical assets and supply chains, shows how the work keeps changing with the world.
