Broker rebrands as Aon completes acquisition

Aon has completed its acquisition of UK-based broker Griffiths and Armour.

The transaction, which was first announced in November 2024, officially went through on 1 January 2025.

As part of the deal, the acquired firm, which specialises in professional indemnity insurance, will now trade as Griffiths and Armour, an Aon company.

The broker, which employs around 200 staff across Liverpool, Manchester, Dublin and London, will also use Aon’s propositions to help enhance its offering.

Matt Donnelly, chairman at Griffiths and Armour, 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.”

Strategy

Aon said its latest purchase forms part of its strategy to further expand its presence in the UK and Ireland.

Jane Kielty, UK chief executive at Aon, said: “We are delighted to welcome our new Griffiths and Armour colleagues to Aon following the completion of this acquisition.

“Griffiths and 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.”
