Global professional services company Aon has completed its purchase of Griffiths & Armour, strengthening its foothold in the UK and Ireland.

The deal, whose financial terms remain undisclosed, was announced last November.

Finalised on 1 January 2025, the transaction makes Griffiths & Armour a wholly owned subsidiary of Aon UK. The entity will operate under the name Griffiths & Armour, an Aon company.

With more than 200 employees, Griffiths & Armour, now part of Aon, is said to deliver a wider array of solutions by leveraging the combined strengths of both companies.

Based out of the UK, Griffiths & Armour brings expertise in professional indemnity insurance and has a presence in general insurance broking.

Aon is maintaining its presence at Griffiths & Armour’s Liverpool office at Princes Dock, along with its teams in Liverpool, Manchester, Dublin, and London.

Aon UK CEO Jane Kielty said: “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.”

Griffiths & Armour chairman Matt Donnelly said: “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.”

Last month, Aon partnered with flood specialist Fathom to enhance its Climate Risk Monitor solution.

This collaboration aims to provide clients with a more detailed understanding of flood risks in the context of climate change.
