The company, which makes Tango and R Whites as well as the fruit juices
and mixers sold under the Britvic name, has drafted in Brunswick ahead of the deal, which is likely to be one of the highest-profile listings on the London Stock Exchange next year, market conditions permitting.
Brunswick partners Tom Buchanan and Mike Smith are leading the account and report to Britvic CEO Paul Moody and finance director John Gibney.
Britvic is also recruiting for an investor relations director and is likely to appoint a new chairman ahead of the flotation to replace Richard North, who quit after he was ousted as chief executive at Britvic shareholder InterContinental Hotels last month.
InterContinental owns just under half of Britvic, while Whitbread and Allied Domecq each hold just under a quarter of the company. PepsiCo holds the remaining five per cent.
Britvic has an annual turnover of £600m a year.
