Nutt starts at Grayling this month. He replaces David Flynn, who joined the agency in February 2016 and last month moved to biotechnology firm Roche as head of PR.
Nutt has 14 years’ experience in the corporate sector, including a stint as board director at The Communication Group. He has worked with clients including De Beers, Grant Thornton, SABIC and Canary Wharf Group.
Sarah Scholefield, Grayling UK CEO, said: "Grayling’s corporate expertise already has a strong and long-established reputation in the UK and beyond. We believe Tom’s experience will deliver an even deeper level of corporate and reputation insight, while continuing to deliver world-class advice and strategic planning to our existing clients.
"We are excited to have him join our UK network and are confident he has the skills to build the profile of our work to current and future clients."
The appointment follows a series of changes at the UK arm of the Huntsworth-owned agency, which recently returned to profit after a period of restructure.
Scholefield was promoted from UK MD to CEO in May and last month saw the appointment of former Ketchum director Andrew Ferguson as creative director. This year also saw the departure of Daniel Cohen, Grayling's global head of brands who led its offshoot Atomic in London
Earlier this month Grayling UK launched a new offer called Grayling Engage, a stakeholder relations and public consultation and engagement practice.
