Marsh McLennan to rebrand in 2026

Marsh McLennan has announced that it will change its brand to Marsh, the name already used by its insurance broking arm.

Effective from January 2026, the firm said it is making the move as it believes that “unifying under one brand will accelerate the impact we deliver to the marketplace”.

As part of the rebrand, the company’s four businesses will adopt the Marsh brand beginning in 2027, following a transition period.

Reinsurance broker Guy Carpenter will be named Marsh Re and management consultant Oliver Wyman will be known as Oliver Wyman, a Marsh business. The Oliver Wyman Group operating unit, meanwhile, will become Marsh Management Consulting.

And Mercer – its HR and financial services arm – will go to market under the new Marsh branding.

“Unifying under one brand will accelerate the impact we deliver to the marketplace and give clients even greater confidence to thrive through the power of perspective,” said John Jones, chief marketing and communications officer at Marsh McLennan.

“The new Marsh brand comes to life with a new logo – a bold design that represents the greater impact we can have with clients and the unique perspectives we offer.”

New arm

Meanwhile, Marsh McLennan also announced that it had created a new unit, Business and Client Services (BCS), to accelerate innovation and centralise investments in operational excellence, data, artificial intelligence (AI) and analytics.

The arm brings together the firm’s technology, data and operations teams under the leadership of Paul Beswick, Marsh McLennan’s chief information and operations officer.

John Doyle, president and chief executive at Marsh McLennan, said: “With the changes announced, our brand will embody the greater value we can create for all our stakeholders, while BCS will drive enhanced client service.

”Both initiatives reflect our steadfast commitment to delivering meaningful outcomes and exceptional experiences for our clients and colleagues.”
