The $65 million (€72m; £45m) creative duties of German energy group Eon have been put up for review.

The client has asked Springer & Jacoby in Hamburg, the same city’s Wieden & Kennedy and Frankfurt’s Publicis to pitch against incumbents Grey Worldwide in Düsseldorf and Munich’s Start.

The media planning and buying business, currently in the hands of MediaCom in Düsseldof, is not affected by the review.
