The energy supplier has approached a number of agencies as it looks to renew its roster. The review is in its early stages with agencies responding to initial questions ahead of a pitch process.
E.ON currently uses a number of small regional agencies to handle its DM. Previously, E.ON used Tequlia\London, which worked on the integrated E.ON business with its sister agency TBWA\London. However, TBWA lost the account to DLKW in 2009.
The DM pitch follows an E.ON digital pitch last year that resulted in the appointment of LBi. The agency works on E.ON's digital creative, user experience, brand communications and mobile work.
E.ON's recent advertising, launched last year by DLKW Lowe, centred on the "Energy Fit" integrated campaign to encourage consumers to improve their energy efficiency and reduce bills. The campaign included E.ON's first TV ad in two years and was backed by print, radio, DM and digital activity.
