The agency won a four-way pitch to lead B2B and B2C campaigns covering eating at work and the working environment.
The campaign will run with the theme ‘Britain needs a workplace that works'.
The account is being led by director Ian Barber. He said: 'Compass Group runs more restaurants in the UK than McDonald's and serves up everything from Tex-Mex to Toad-in-the-Hole. There is a real opportunity to position the business as experts in workplace eating and the working environment.'
Compass Group UK & Ireland is part of the wider Compass Group which operates in 62 countries, with more than 360,000 employees.
