Aon, a large global insurance and reinsurance broking group, has announced the successful completion of its acquisition of Griffiths & Armour.
The deal, finalised on January 1, 2025, enhances Aon’s strategy to broaden its regional footprint in the UK and Ireland.
Moving forward, Griffiths & Armour, a well-established UK insurance broker, will operate under the name “Griffiths & Armour, an Aon company.”
This acquisition comes after Aon signed a definitive agreement on November 1, 2024, to acquire Griffiths & Armour, aligning with Aon’s expansion strategy in the UK and Ireland.
Upon completion, Griffiths & Armour will become wholly owned by Aon UK Limited. With this acquisition, Griffiths & Armour gains access to a wider range of solutions, combining the strengths of both organisations to drive further growth.
Jane Kielty, UK CEO of Aon, commented: “We are delighted to welcome our new Griffiths & Armour colleagues to Aon following the completion of this acquisition. Griffiths & Armour is an outstanding business with an exceptional reputation in the market. Together we will focus on providing our clients with excellent, market-leading expertise and our complementary cultures and capabilities will create an unparalleled offering across the UK and Ireland.”
Employing over 200 professionals, Griffiths & Armour is renowned for its expertise in professional indemnity insurance and its solid foundation in general insurance broking.
As part of the integration, Aon has pledged to continue supporting Griffiths & Armour’s Liverpool office at Princes Dock, alongside its teams in Liverpool, Manchester, Dublin, and London.
Carl Evans, Chairman of Griffiths & Armour, said: “Joining the Aon family reflects our shared commitment to deliver exceptional client service, innovative solutions, and maintain a culture built on trust and integrity. It will enable us to continue to deliver exceptional client service with an unwavering focus on securing the best outcomes for our clients, colleagues, and partners.”
Matt Donnelly, Chairman of Griffiths & Armour added: “This collaboration enables us to enhance our offering, extend our reach, and build on the strong foundations we’ve developed in our long history, creating new opportunities as we continue to innovate and lead in a rapidly changing industry.”
