Last updated August 31, 2026
Overview
Benfield Group was an independent reinsurance and risk intermediary serving insurance companies, reinsurers, governments, and multinational corporations. Its principal role was to arrange and broker reinsurance, connecting organizations seeking to transfer insurance risk with reinsurance providers willing to assume that risk. The company was based in London and incorporated in Bermuda, and it developed an international operating network spanning more than 50 offices in the United Kingdom, the United States, Continental Europe, Bermuda, and Asia. The business originated in 1973 as Benfield, Lovick, and Rees & Company, commonly known as BLR, a Lloyd's broker. A management buyout in 1988 created the Benfield Group structure and provided the platform for subsequent expansion. During the 1990s and early 2000s, Benfield broadened its scale and market reach through mergers involving Ellinger Heath Western, Greig Fester, and E.W. Blanch. These transactions helped build a larger international intermediary focused on the specialist requirements of insurers and reinsurers. Benfield's core business remained reinsurance brokerage. More than 90 percent of its revenue came from this activity, according to the reference material. In practical terms, its work included helping clients place reinsurance protection, structure risk-transfer arrangements, and access international underwriting capacity. The company also operated in selected areas of primary insurance brokerage through Benfield Corporate Risk, which addressed complex risk-management and risk-transfer needs for corporate clients. Benfield became a public company on the London Stock Exchange in 2003 and was later a constituent of the FTSE 250 Index. Its independence ended when Aon Corporation announced on 22 August 2008 that it had agreed to acquire the group for approximately $1.43 billion. The transaction was completed on 28 November 2008. Following the acquisition, the business operated within Aon's reinsurance brokerage operations under the Aon Benfield name. That branding continued until 2018, after which the Benfield identity ceased to be used as the principal operating brand. Benfield is therefore best understood historically as a major specialist reinsurance intermediary rather than as an active standalone brand.
History
Benfield Group's origins lay in the Lloyd's insurance market. The business was established in 1973 as Benfield, Lovick, and Rees & Company, generally abbreviated to BLR. It began as a Lloyd's broker, operating in the specialist insurance and reinsurance environment centered on London's Lloyd's market. Its early role was that of an intermediary, helping clients obtain insurance-related capacity and supporting the placement of risks with underwriting markets. A management buyout in 1988 resulted in the formation of Benfield Group. The change created a distinct corporate platform from which the company could expand beyond its earlier identity and develop a broader international presence. During the 1990s and the early years of the 21st century, Benfield pursued growth through combinations with other insurance and reinsurance intermediaries. The reference material identifies mergers with Ellinger Heath Western, Greig Fester, and E.W. Blanch. These transactions increased the group's capabilities, geographic reach, and access to clients and markets. Benfield's expansion was principally directed toward reinsurance brokerage. Unlike a reinsurer, which assumes insurance risk on its own balance sheet, a reinsurance broker acts as an intermediary between a risk purchaser and reinsurance providers. Benfield helped insurance companies and other clients arrange reinsurance protection and connect with international sources of capacity. Its customer base included many of the world's leading insurance and reinsurance companies, government entities, and global corporations. The company also maintained a primary insurance brokerage operation through Benfield Corporate Risk, serving selected corporate clients with complex risk-management and risk-transfer requirements. The group's international structure included more than 50 offices across the United States, the United Kingdom, Continental Europe, Bermuda, and Asia. Although headquartered in London, Benfield was incorporated in Bermuda, reflecting the importance of Bermuda as a center for insurance and reinsurance business. Reinsurance brokerage was the dominant economic activity, accounting for more than 90 percent of revenue according to the cited reference material. Benfield became publicly traded on the London Stock Exchange in 2003. It subsequently became a constituent of the FTSE 250 Index, placing it among the larger companies represented in that market segment. Public ownership gave the company greater visibility and access to capital while it continued to develop as an international specialist intermediary. The company's period as an independent public group ended in 2008. On 22 August of that year, Chicago-based Aon Corporation announced that it had agreed to acquire Benfield for approximately $1.43 billion. The transaction was completed on 28 November 2008. Benfield thereafter became part of Aon's reinsurance brokerage operations. The business continued under the Aon Benfield name for a period, preserving the acquired company's specialist identity while integrating it into Aon's global network. The Aon Benfield branding remained in use until 2018. After that point, the Benfield name no longer operated as the principal standalone identity of the business. Benfield Group is consequently a defunct independent brand and corporate group, although its activities and capabilities became part of Aon's continuing reinsurance brokerage business.
