Innocent is looking for agencies with strong creative credentials to work alongside its in-house creative team. The scope of work will include TV, press, outdoor, radio and heavily-weighted digital elements.
The incumbent, Lowe London, which won the account in October 2005, is understood to be repitching for the business.
The brand now has a 68 per cent share of the smoothies market, and an ?annual turnover of £100 million.
Earlier this month, Innocent appointed the digital agency Soup to handle online creative for its summer events programme.
Innocent did not return calls as Campaign went to press.
