The Diot-Siaci Group has announced the creation of Diot-Siaci Global Markets (DSGM), a new subsidiary, as part of its international expansion strategy.
DSGM will open an office in London, focused on large exposures and international clients, and is seeking authorisation as an insurance intermediary in France by ORIAS and in the UK by the FCA, subject to regulatory approval.
London has been selected for its access to the global insurance market, international capabilities, and investment solutions. The new office is intended to enhance Diot-Siaci’s global profile, strengthen its specialist offerings, and attract both new and existing clients as the group aims to position itself as a Franco-European alternative to major brokers.
The decision to establish a presence in London comes at a time when the city’s insurance market continues to demonstrate its significance within the sector. In 2024, London Market companies reported a total premium income of £49.273 billion, with £43.774 billion underwritten directly in London and a further £5.499 billion from ‘controlled business’ managed by London-based operations.
However, the latest IUA data also points to a moderation in growth, with the London Market’s premium income rising by 1.7% in 2024. This follows higher increases of 10% in 2023 and 25% in 2022, suggesting that the market is entering a period of more stable expansion after several years of rapid growth.
The launch of DSGM also follows an investment from private capital investor Ardian in August, supporting the group’s strategy to accelerate growth across business lines and geographies.
Subject to FCA approval, DSGM will provide broking services across all general property & casualty (P&C) damage and liability policies, targeting sectors with high insurance complexity such as energy, financial institutions, transactional risks, complex construction, infrastructure, and defence industries. The London office will also offer consulting, programme design, optimisation, and placement for both direct insurance and reinsurance globally.
The branch will be overseen by Florence Louppe (pictured above), managing director of Diot-Siaci Corporate Solutions, with Edouard Marron appointed as CEO of Diot-Siaci Global Markets in addition to his role as managing director global specialty.
Pascal Calmels will lead local operations for the branch. Calmels previously served as head of mining at Miller Insurance LLP and held senior positions at WTW, including head of Asia-Pacific natural resources – downstream.
“The opening of our London office is designed to give our global clients and international entities direct access to international markets, while further strengthening the development of our global specialties,” Louppe said.
Cedric Charpentier, Diot-Siaci Group CEO, said, “The London office marks a key milestone in the group’s strategic plan to reach €2 billion in revenue by 2029, two-thirds of which are expected to come from outside France.”
In 2024, Diot-Siaci reported a gross turnover of €1.03 billion, with nearly half of this revenue generated from international operations, representing a 24% increase on the previous year.
