BMS Group
BMS Group was established in 1980 as a family-run London market broker and has grown into a prominent independent intermediary in global specialty insurance. The Cook family retains majority control, with Nick Cook serving as Group CEO. The firm's wealth originates from decades of insurance and reinsurance brokerage, a sector where London remains a global hub for pricing complex risks ranging from aviation to political violence. The firm places risk across five principal verticals: reinsurance, specialty insurance, international construction, marine, and financial institutions. BMS is not an underwriter — it acts as an intermediary, structuring and placing risk with Lloyd's syndicates and global carriers. The 2022 sale of a minority stake to BCI, one of Canada's largest institutional investors, valued the firm at over £1 billion (per the Financial Times, 2022). That transaction introduced permanent institutional capital without disturbing the Cook family's operating control, an architecture rare in the broker space. BMS has scaled through both organic growth and targeted acquisitions, including the 2024 purchase of Australian specialty broker Bluebook Insurance Brokers to expand its Pacific reach. The firm employs over 1,000 professionals across offices in London, Sydney, Singapore, and other hubs (per BMS Group, 2024). The Cook family participates directly in the firm's strategic direction rather than operating as passive shareholders, a posture consistent with the London market's tradition of owner-operators. Structurally, BMS Group differs from most family offices because it operates as an active trading enterprise rather than an allocator of financial assets. The Cook family's wealth is not managed through a diversified portfolio of external managers but is instead concentrated in the operating equity of the brokerage itself — making it a pure-play insurance dynasty rather than a generalist family office.

Frequently asked questions
Who runs BMS Group and where does the family's wealth come from?
Nick Cook is the Group CEO of BMS Group, a specialist insurance and reinsurance broker founded by the Cook family in 1980. The family's wealth originates from decades of operating in the London insurance market, placing complex specialty risks. The Cooks retain majority ownership and active management control of the firm.
How does BMS Group generate its revenue?
BMS generates revenue through brokerage commissions and advisory fees earned by placing specialty insurance and reinsurance risks. It operates across verticals including reinsurance, marine, construction, financial institutions, and specialty lines such as political risk and trade credit. The firm does not underwrite risk itself — it acts as an intermediary between buyers of insurance and carriers in the London market and globally.
Is BMS Group structured as a family office or an operating business?
BMS Group is structured as an operating specialty insurance brokerage, not a conventional family office. The Cook family's wealth is concentrated in the equity of the operating company rather than being managed through a diversified portfolio of external investments. This makes BMS more akin to a family-controlled enterprise than a family office in the traditional allocator sense.
What was the significance of the BCI investment in BMS?
In 2022, British Columbia Investment Management Corporation (BCI) and Preservation Capital Partners acquired a minority stake in BMS at a valuation exceeding £1 billion. The transaction provided permanent institutional capital while preserving the Cook family's majority control and operational leadership, a structure designed to fund expansion without forcing a generational transition or exit.
Does BMS Group maintain philanthropic structures separate from the business?
BMS Group does not publicly disclose a dedicated philanthropic foundation or charitable arm separate from the brokerage enterprise. The firm's public communications focus on its core insurance and reinsurance operations rather than non-commercial activities.
