His replacement as UK corporate MD is Helen Searle, who joined the WPP-owned agency three years ago as a corporate director.
Escott replaces Geoff Beattie, who was last week appointed to lead C&W’s new corporate consulting unit.
Escott joined C&W in 2009, initially as a director in its corporate and public affairs practice. In 2012 he founded the Cohn & Wolfe Political Counsel, the agency’s first public affairs service.
Searle’s promotion follows a period of growth at C&W’s UK corporate arm, which has doubled in revenue and expanded its services over the past four years, working with clients include Warburtons, Twinings, Ferrero, Asia Pulp & Paper, Lloyds Banking Group and Bayer.
The UK is now C&W’s biggest territory for its corporate practice. UK CEO Scott Wilson said: "Helen has been a critical part of our recent growth and her experience in creative global and UK corporate brand communications will power us even further forward."
C&W chief executive Donna Imperato said: "Demand for our corporate reputation work has grown significantly around the world and Andrew has been a major contributor to our success. Under Andrew’s leadership, I see our Corporate Practice continuing to be a significant driver across Cohn & Wolfe markets."
Escott, whose new job title is global corporate practice leader, said: "The global business environment has never been tougher so our clients need a partner that can seamlessly both protect and promote their business. That’s what we have built in London and it has been a successful and differentiated model driven by a hugely talented team.
"Helen is a great leader, a critical part of our recent success and I have no doubt she will take the business even further."
C&W's Corporate Practice covers aspects of reputation management including crisis and issues management, business-to-business comms, CSR and sustainability, employee engagement, public affairs and corporate storytelling.
Before joining C&W, Escott’s roles included head of commercial relations at the NHS Confederation and account director at APCO Worldwide.
