With total written premiums of approximately $4 billion in 2025, Miller, an independent specialty insurance and reinsurance brokerage, celebrated a milestone year with the addition of 180 new employees.
Gross written premiums were $4 billion, unchanged from the previous year, but total revenue rose 15% to £314 million in 2025, compared with £271 million in 2024, marking Miller’s fifth consecutive year of growth.
With 180 new hires added this year, bringing the firm’s headcount to more than 1,300 people, the brokerage continues to move forward under a new brand and visual identity under the slogan “Go Be Great”.
In June 2025, Miller completed the acquisition of AHJ Holdings Ltd., the ultimate parent company of Alwen Hough Johnson Limited and AHJ Europe AS. The acquisition gives the broker immediate scale and capabilities in treaty reinsurance, allowing it to leverage AHJ’s strong position in the Nordic, Caribbean and North American markets.
As early as October 2024, Miller completed the acquisition of Madrid commercial re/insurance broker Bruzon, and the integration and brand transformation of the Spanish business will also be completed in 2025.
James Hands, CEO of Miller, commented: “2025 is another milestone year for Miller, as we achieve our fifth consecutive year of profitable growth. This reflects our efforts to strengthen our proposition to customers and insurance capability providers through a wider product range, expanded geographic coverage and continuously improving customer service.
“Last year, we significantly expanded our footprint in capabilities and geographies with the acquisition of AHJ, marking a significant change in the scale of our reinsurance platform. We also successfully integrated Spanish broker Bruzon and continue to be one of the fastest growing players in Asia, including the launch of Miller Korea and diversification into Japanese non-maritime operations.
“We have built on this momentum and acquired Shields Reinsurance in early 2026 (subject to regulatory approval), further expanding our cross-border presence, enhancing our product and service offerings in the MENA region and enabling us to operate locally to further serve new and existing customers.
“However, Miller’s aim has never been to grow for growth’s sake and we continue to focus on opportunities to build our platform by bringing real value, establishing an international footprint that reflects and complements our profile as one of London’s most highly regarded specialist brokers.
“Having launched our new brand with the slogan ‘Go Be Great’ early last year, we continue our unwavering commitment to innovation, exceptional customer service and developing the best talent in the industry. We have welcomed 180 new employees to our business and continue to diversify our offering and strengthen our expertise with key new hires, including the appointment of MGA CEO and CUO, while launching innovative customer solutions such as MillerBoost, our advanced real estate intelligence tracking tool.
“Looking ahead, we are excited about future growth and believe more passionately than ever that our combination of independence, expertise and international scale make Miller a uniquely attractive option for our clients and colleagues.”
