The PR agency will represent the group’s portfolio, which includes Michelin-starred Petrus, Maze and the Savoy Grill, taking over from incumbent agency Lotus PR.
Part of Roche’s brief will be to launch Heddon Street Kitchen in Regent Street’s Food Quarter later this year.
Rochelle Cohen, managing director, Roche Communications said: "Our brief is to bring these quality restaurants, their chefs and their menus to the forefront of London's ever-competitive dining scene while launching venues for the group."
Jo Livingston, the group’s comms director, said the company picked Roche because of the "energy and creativity" it brought to its pitch and because of its proactive approach to comms.
