The privately owned company is talking to three agencies about the business.
These agencies are thought to be St Luke's, Vallance Carruthers Coleman Priest and The Leith Agency.
Jordans is looking to appoint an agency across its product range, which includes cereals and cereal bars. Recent product launches include its Frusli cereal bar, which has been promoted through a sampling exercise.
The company, owned by the W Jordan family, began its last major TV ad campaign in November 2002 through the Norwich-based agency Vital Design & Advertising.
Vital's ad campaign for Jordans used the line "All the best from Jordans country" and featured a voiceover from Joanna Lumley. The campaign, which targeted ABC1 housewives, aimed to position the brand as ecologically friendly by promoting its decision not to use pesticides.
Jordans now faces increased competition in the cereal bar market with the entrance of rival products from the cereal giants Cereal Partners and Kellogg.
Media planning and buying, handled by Media Planning Group, is not being reviewed.
Paul Weddepohl, the head of marketing at Jordans, was unavailable for comment as Campaign went to press.
