Egg's retained agency Mother will still lead the creative efforts, and is currently working on a new brand advertising campaign for the bank.
EHS Brann is charged with developing Mother's creative blueprint for online advertising. The agency will work on a project basis.
The last work developed by Mother was "Brilliant Industries", a company with a steady supply of outlandish ways of keeping finances under control, including the "La La La I'm Not Listening" device.
The new television campaign is due to break after Easter, although details have yet to be unveiled. Egg's online advertising runs continually, but will be updated when the new television advertising is launched. Its online ads are mainly brand ads or ads promoting the company's Egg credit card.
EHS Brann will report to Patrick Muir, UK marketing director for Egg.com.
