MarshBerry Advises MacKay Corporate Insurance Brokers on Sale to Brown & Brown (Europe)

London – MarshBerry, a global leader in investment banking and consulting, announced that it served as the sole financial advisor to Alan R Mackay & Company (trading as MacKay Corporate Insurance Brokers) in its sale to Brown & Brown (Europe). The transaction closed on September 1, 2026.

Headquartered in Ayr, Scotland, MacKay Corporate Insurance Brokers is a Chartered insurance broker specializing in property and casualty insurance solutions. The firm has built a leading reputation across Scotland, including notable expertise in the energy sector.

The acquisition represents a significant milestone for Brown & Brown (Europe), marking its first retail insurance acquisition in Scotland and providing the organization with an important platform for future growth in the Scottish market.

MarshBerry was engaged by MacKay Corporate in 2025 to evaluate strategic options and guide the shareholders through a sale process. The firm prepared comprehensive marketing materials and conducted a highly competitive auction involving numerous leading UK insurance brokers, including private equity-backed consolidators and major international broking groups. Brown & Brown was ultimately selected due to its transaction structure, long-term strategic alignment, and strong cultural fit with MacKay Corporate.

“MacKay Corporate has built an outstanding reputation over many years and occupies a unique position in the Scottish insurance market,” said John Nisbet, MarshBerry Managing Director. “We were proud to advise the shareholders throughout this process and help identify a partner that not only recognized the firm’s value and market leadership, but also shared its long-term vision. Brown & Brown’s entry into Scotland through the acquisition of such a highly respected business creates exciting opportunities for continued growth for clients, employees and stakeholders alike.”

MacKay Corporate’s three directors will remain with the business to support its continued development and help drive Brown & Brown’s expansion across Scotland.

This transaction underscores MarshBerry’s commitment to helping firms achieve value realisation objectives and strategic growth through merger & acquisition (M&A) initiatives in the financial services sector. MarshBerry’s team brings extensive experience in advisory services, supporting clients through the complexities of valuation, solicitation, negotiation and successful transaction execution.

Terms of the transaction were not disclosed.
