The advertising review comes as Unilever considers a relaunch of its Birds Eye brand in the UK, a move it may extend to other countries in Europe.
Unilever has, however, denied it is undertaking a pan-European review of its advertising.
The company currently uses a variety of agencies in different countries, although many of its advertising campaigns do run across several markets.
McCann-Erickson is to take part in the review and defend its account, but Unilever refused to comment on other agencies that it has asked to pitch. Agencies that work for Unilever in the UK include BMP DDB, Bartle Bogle Hegarty, Ogilvy & Mather, Lowe & Partners and Mother.
Brands included in the frozen foods account are Wall's Carte d'Or ice cream, Cornetto and Viennetta, as well as Birds Eye frozen ready meals and its potato range, which includes Potato Waffles.
The review does not include Captain Birds Eye fish range, which is handled by HHCL/Red Cell.
A spokesperson for Unilever said that he expects a shortlist of agencies to be drawn up by mid-October and that the review will be completed by the end of the year.
The review is not affecting media agencies at this stage, although this could change in the future, the spokesperson said. Carat handles media for Unilever Ice Cream & Frozen Food in the UK, along with Initiative Media.
