The incumbent, McCann Erickson, is understood to have had creative differences with the company and will not repitch for the business. Media, handled by Initiative, will not be included in the review.
The review is being handled by the AAR and encompasses the Werther's Originals and Mingles brands, in addition to the Bendicks of Mayfair line.
McCann won the Bendicks brief in July 2004 after a three-way shoot-out against Soul and the incumbent, Unity.
The agency later picked up the Werther's Originals account without a pitch. McCann's first work for the brand was to update its image. It replaced the grandfather and grandson situations with a more modern family.
The agency's work for Bendicks included a £2 million TV push for its Mingles and Gorgeous chocolate brands, which targeted women with a "mini drama" based around a footballer's wife, and introduced the line: "It's the Bendicks that counts."
Stephen Whyte, McCann London's chief executive, said: "It's been a pleasure to work with Bendicks for the past three years."
