Global insurance and reinsurance broker Aon has signed a definitive agreement to acquire UK-based insurance broker Griffiths & Armour, a move that aligns with its UK and Ireland expansion strategy.
Upon completion of the transaction, Griffiths & Armour will become wholly-owned by Aon UK Limited and is proposed to go to market as “Griffiths & Armour, an Aon company”.
This partnership will offer clients a wider range of solutions by combining the strengths of Aon and Griffiths & Armour. This creates a foundation for growth in the UK, Ireland, and beyond.
The closing of the transaction is expected to to occur in the first quarter of 2025, subject to customary conditions, including regulatory approvals.
Greg Case, CEO of Aon, commented: “As we continue to go further, faster to help our clients navigate growing uncertainty and volatility, we are looking forward to welcoming Griffiths & Armour to Aon.
“Our complementary capabilities and cultures will create unmatched client and colleague experiences across the UK and Ireland and contribute to our global 3×3 Plan to accelerate our Aon United strategy.”
Griffiths & Armour, headquartered in northern England, is a provider of professional indemnity insurance and general insurance brokerage services.
With a team of approximately 200 employees, the company has built a strong reputation both nationally and internationally for their specialised expertise.
As part of the acquisition, Aon is committed to Griffiths & Armour’s Liverpool office at Princes Dock and its strong team in Liverpool, Manchester, Dublin and London.
Aon and Griffiths & Armour will continue to operate independently until closing of the transaction.
Carl Evans, CEO of Professional Risks for Griffiths & Armour, said: “Becoming part of the Aon family is the result of a meticulous search for a trusted partner with whom we can work, to ensure the future success of Griffiths & Armour and to enable us to enhance, grow and expand our unique client proposition. This proposition is founded on a culture that has been created and refined over the last 90 years, of which we are immensely proud.”
Matt Donnelly, CEO of General Insurance for Griffiths & Armour, added; “We have long-regarded Aon for its professionalism and client service excellence. In them we have found a partner who will not only help deliver continued growth, but also preserve and embrace the culture that we and our client community hold dear. We very much look forward to this next chapter.”
