The energy company has put together a shortlist for its £20 million account that does not include the agency.
Included on the list are WCRS, DDB and Delaney Lund Knox Warren & Partners.
The account went up for pitch in December last year, following E.ON's appointment of Jeremy Davies from the Santander-owned Abbey, which is handled by WCRS, as its director of brand and communications.
TBWA\London picked up the business in 2007, and has produced a series of brand and retail campaigns for E.ON, as well as activity to support its FA Cup sponsorship. Powergen rebranded as E.ON in 2007.
