The insurance company, whose ads star Michael Winner, has previously used a number of agencies, including Red Cell, on a project basis for its direct work. The new appointment follows a two-week pitch process.
Esure has been using Winner since October 2002, when it shifted its advertising in-house. An Esure spokeswoman said its direct work would continue to feature the former film director.
Carat, Esure's media agency, and Carlson Digital, which handles online projects for the insurer, are un-affected by the appointment.
