Tamesis Ltd

What Tamesis Ltd does

Tamesis Ltd (operating as Tamesis DUAL) is a London-headquartered specialty excess of loss treaty reinsurance business established in October 2011 and commencing underwriting in 2012. The company operates as the first treaty reinsurance Managing General Agent (MGA) with a focus on specialty excess of loss, offering specific and composite reinsurance and retrocessional solutions across blended and composite asset-based classes including Marine, Offshore Energy, Onshore Energy, Property, Aerospace, Terrorism/Political Violence, War, and Political Risks. Capacity is provided by Orient Insurance PJSC (rated AMBest A+ and S&P A+), enabling up to USD 15 million per program/per interest/per binder.

The firm functions as an Appointed Representative of DUAL Corporate Risks (FCA authorized, firm reference 312593) and sits within the DUAL Group, itself a subsidiary of Howden Group Holdings, a global insurance group with 16,000 employees across 55 countries. Geographically, Tamesis operates from three offices in London (headquarters), Miami (supporting North America, South and Central America, and the Caribbean), and Cologne (EEA servicing via Tamesis DUAL Europe GmbH). Insurance intermediary activities for EEA clients are conducted through the German authorized entity, with Tamesis DUAL Europe GmbH additionally authorized by the FCA under firm reference 984578.

Tamesis's go-to-market is wholesale only: the company distributes through insurance brokers and direct engagement with (re)insurers rather than direct-to-customer channels, and generates revenue through commissions and fees earned on underwriting reinsurance on behalf of capacity providers under a recurring MGA model. Customer segmentation is geographically defined (London Market and international (re)insurers, North American small/mid-sized domestic and specialist insurers, Latin American and Caribbean (re)insurers, and EEA clients), with a multi-class product surface serving as the primary differentiator. The leadership team is led by founder and Managing Director Tony Lovett, with Nicholas Toth (formerly of Argenta Syndicate Management, QBE Reinsurance, and GE Reinsurance) appointed as Director of Underwriting in April 2022 to support global expansion. Pricing is not publicly disclosed and is handled via quote-based, individually negotiated arrangements.

Expansion highlights4 records

Broad incumbents

• Guy Carpenter: Guy Carpenter is a global reinsurance intermediary and broker serving insurers and reinsurers. It is comparable through its treaty focus and broker-led distribution to (re)insurers, although it does not provide the same delegated underwriting capacity model as Tamesis.
• Howden Group Holdings: Howden is a global insurance intermediary group with specialty insurance, reinsurance, MGA, broking, and data capabilities. As Tamesis's ultimate parent, it provides a broad ecosystem and institutional-scale comparator, although it is not a pure-play treaty reinsurance peer.
• Aon: Aon provides global insurance, reinsurance, and risk solutions, including services for insurers. Its international intermediary reach and reinsurance capabilities make it a broad incumbent comparator to Tamesis's specialist B2B MGA model.
• Convex Group: Convex is a specialty insurer and reinsurer with a global, multi-line risk portfolio. Its appetite for complex specialty risks makes it a useful product and market comparator for Tamesis's multi-class treaty offering.
• DUAL Corporate Risks: DUAL Corporate Risks is a specialist underwriting agency and the authorized principal platform for Tamesis DUAL, making it a directly relevant organizational and product comparator. It is a broader, affiliated platform rather than an independent direct competitor.
• SCOR: SCOR is a global reinsurance group underwriting a broad portfolio of life and non-life risks. It is comparable to Tamesis through its global treaty and specialty reinsurance orientation, although SCOR is a large carrier rather than a specialist MGA.
• Hannover Re: Hannover Re is a global reinsurer providing capacity across property, casualty, and specialty lines. Its broad specialty-risk and treaty capabilities make it a relevant institutional-scale comparator for Tamesis.
• Fidelis Insurance Group: Fidelis is a specialty insurer and reinsurer with exposure across multiple complex risk classes. It is comparable to Tamesis through its global specialty underwriting and reinsurance focus, while operating at substantially greater scale.
• RenaissanceRe: RenaissanceRe is a global specialty reinsurer underwriting property, casualty, and specialty risks. It is a relevant product-category and scale comparator for Tamesis's treaty reinsurance activity.
• Chaucer Group: Chaucer is a specialty insurance group underwriting complex risks in the London and international markets. Its specialty underwriting orientation and London-market presence make it relevant to Tamesis's excess-of-loss treaty proposition.
