The agency will now be responsible for all print, online and television marketing.
Previously, broadcasting was handled by Beattie McGuinness Bungay, the direct marketing account was held by EHS Brann and digital was handled by Grand Union.
Kevin Peake, director of marketing at npower, says: “Our aim was to find an agency which has everything under one roof and a proven track record in changing market perceptions of differing industries.”
The agency will also work on npower’s energy efficiency campaign starring Aardman Animation’s Wallace and Gromit. The latest execution launched last month and focuses on loft installation.
The energy supplier is the title sponsor of the Ashes cricket series between England and Australia, the third test of which ended in a draw yesterday (4 August).
Its current Ashes campaign features Aardman-created characters playing cricket on a village green and will promote the £100 discount the company offers to dual-fuel monthly direct debit customers on their first anniversary.
The energy company is currently trialling customer retention programme npower Select that offers dual fuel monthly direct debit customers a choice of 100 off their annual energy bill or alternatives that include 120-worth of Marks & Spencer vouchers or 140-worth of RAC breakdown cover.
