The company, which owns properties including the Trafford Centre in Manchester, has sent RFIs to agencies and plans to hold chemistry meetings on 20-21 October. The process, which is being run by Oystercatchers, is expected to be completed by the end of December.
The brief requests media planning and buying services. Intu has set aside about £5 million for the first, year-long phase of the campaign.
Roger Binks, Intu’s customer experience director, said: "We’ve been overwhelmed by how well people have taken to the brand. We’re now looking for long-term partners who can help tell this story to an even wider audience."
