Arthur J. Gallagher Holdings (UK) Limited, part of the global insurance brokerage, risk management, and consulting group Gallagher, has announced the appointment of David Rush as an Independent Non-Executive Director.

He led audit engagements for many of Deloitte’s major and publicly listed insurance clients and advised on mergers and acquisitions, as well as regulatory, accounting, and internal control matters.
In addition to his professional career, he has invested in and held board roles with start-ups focused on health, renewable energy, and recycled resources. He currently serves as Chairman of WeAre.xyz, an organisation developing AI-powered tools for collaborative online archives.
At Gallagher, he will take on the role of Chair of the Audit Committee (subject to regulatory approval), succeeding Jamie Drummond-Smith, who will step down as a Non-Executive Director in February 2026 after 12 years with the company.
Rush said: “Gallagher’s presence in the UK has gone from strength to strength over recent years and I am looking forward to playing a part in its continued growth. Having worked with many clients in the insurance sector I was impressed by the culture at Gallagher, which is built on integrity and service and remains at the core of its approach to looking after clients.”
Michael Rea, CEO of Gallagher in the UK & Ireland, commented: “The appointment of David reflects our goal of bringing further independent, external perspectives and expertise to our board. David joins Gallagher’s UK business at an exciting time as we have recently completed the acquisition of AssuredPartners which brings over 1,000 new talented colleagues in the UK & Ireland into our team giving us an enviable springboard for further expansion.”
Sue Langley, Non-Executive UK Chair of Gallagher, added: “Having enjoyed a long career at Deloitte, David brings a wealth of market knowledge and experience and I am thrilled to welcome him to our UK board. David has a strong track record of working with large organisations in the insurance sector throughout his career and his insights will prove highly valuable as we continue to expand.”
