Miller Insurance Services LLP used acquisitions in 2025 and early 2026, alongside regional hiring, to build its international reinsurance platform, reporting £314 million in revenue while pursuing further growth through its planned acquisition of Shields Reinsurance Brokers.
The specialist re/insurance broker said revenue for the year ended December 31, 2025, rose 15% from 2024. Total gross written premium placed reached about £3.7 billion.
Its acquisition activity in 2025 included the purchase of AHJ, which gave Miller immediate scale in treaty reinsurance and access to Nordic, Caribbean and North American treaty markets.
The company also completed the integration and brand transition of Spanish broker Bruzon following its 2024 acquisition. The business now operates fully under the Miller brand.
“2025 has been another milestone year for Miller as we deliver a fifth consecutive year of profitable growth,” said chief executive James Hands. “This reflects our efforts to strengthen our proposition for clients and insurance capacity providers through a broader product range, increased geographic reach and continuous improvement of client service.”
Miller’s transaction activity continued into 2026 with its agreement to acquire Dubai-based Shields Reinsurance Brokers, subject to regulatory approval.
Founded in 2017, Shields provides facultative and treaty reinsurance across specialty classes. The broker is regulated by the Dubai Financial Services Authority and has been an admitted broker at Lloyd’s since 2018.
Shields serves insurers, reinsurers and takaful providers across the Middle East and North Africa and other markets. The transaction is expected to close in the second quarter of 2026.

“Last year, we significantly expanded our footprint by both capability and geography with the acquisition of AHJ, marking a step 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 launching Miller Korea and diversifying into Japanese non-marine lines,” Hands added.
The broker also made senior appointments across its reinsurance operations.
In January 2026, Miller appointed Paul Jenkins to its North American property business. In December, Miller appointed Andreas Ehrencrona as head of facultative reinsurance for the Nordic region following the AHJ acquisition. The company also named Sailesh Divakaram head of treaty Asia, based in Singapore.

Miller welcomed 180 new employees during 2025, taking total headcount to more than 1,300.
The broker also appointed an MGA chief executive officer and chief underwriting officer while launching MillerBoost.
It also introduced a new brand and visual identity under the tagline “Go Be Great.”
“However, Miller’s goal has never been growth for growth’s sake, and we continue to focus on opportunities where we can build our platform by bringing true value,” Hands said.
