Why Derek Henry’s Sudden Rise to Interim CEO at Gallagher Could Redefine the Company’s Future—And What It Means for Investors
Ever wondered what it takes for an insurance giant to not just survive but thrive in a market teeming with competition? Gallagher’s insurance broking business in Ireland just flipped the script—and then some. After snapping up AssuredPartners in 2025, they didn’t just add a few employees—they doubled down, integrating several established Irish firms like Gallivan Murphy and O’Donovan Insurance into a powerhouse team of around 600 people. Talk about growth on steroids! But it’s not just about numbers—it’s about leadership, vision, and strategy. Enter Derek Henry, the new interim chief executive, whose deep expertise in personal lines and SME insurance seems tailor-made to steer this behemoth through its next phase of expansion. Change is in the air—was Ronan Foley’s exit the price of progress, or just part of the natural shakeup? One thing’s for sure: Gallagher’s bold moves are reshaping the Irish insurance landscape, and you’ll want to keep your eyes peeled on what they do next. LEARN MORE.
Gallagher’s insurance broking business in Ireland is entering what it describes as a new phase of growth following the integration of several Irish firms acquired as part of its purchase of AssuredPartners in 2025.
The acquisition, which was completed in August last year, brought around 300 new employees into the business in Ireland and included a number of established brokers such as Gallivan Murphy Insurance Brokers, O’Callaghan Insurances, O’Donovan Insurance, Fitzgerald Insurances and CFM Group.
The deal significantly expanded Gallagher’s presence in the Irish market and increased the size of its local workforce to around 600 people.
As part of the next stage of development, the company has announced changes to its leadership team in Ireland, with Derek Henry set to take on the role of interim chief executive, subject to regulatory approval from the Central Bank of Ireland.
He will be responsible for leading the enlarged Irish operation, which now operates across commercial lines, personal lines and financial services and includes the First Ireland brand.
Henry joined Gallagher in 2021 and currently serves as managing director of digital distribution within the group’s UK business.
In that role, he oversees specialist motor and property operations and has worked extensively in the personal lines and SME insurance markets.
The company said his experience will be important as it integrates the businesses acquired through AssuredPartners and continues to expand its presence in Ireland.
Nick Harris, chief executive of Gallagher’s insurance broking division covering the UK and Ireland, said the appointment reflects the company’s focus on strengthening its leadership structure as the Irish business grows.
“Derek’s extensive experience in personal lines and SME insurance makes him well placed to lead our Ireland operations as we enter a new phase of growth and integrate the colleagues and businesses that joined us via the AssuredPartners acquisition,” said Harris.
“As a result of the changes, Ronan Foley has left Gallagher and we wish him all the best for the future.”
He said the integration of the newly acquired firms and employees marks a significant step for the company’s operations in the market.

As part of the changes, Ronan Foley has left the business.
The company said it wished him well for the future as it moves forward with the next phase of its strategy in Ireland.
