At the same time the agency has appointed Fallon's Caroline Collinson-Jones as a senior planner.
Reporting into creative founder Ben Priest, Lloyd and Turner will now take full responsibility for Adam & Eve's digital creative output as well as hiring further talent to build and expand the agency's digital capabilities.
Priest said: "We are expanding our digital offering and Simon and Christine are the perfect next piece of the jigsaw. They do great work and we're delighted their coming."
The pair started their career at Glue where they worked on clients such as Virgin Trains, Sky, MTV, Virgin Money and Mini, for which they won Cannes Gold in 2008.
They joined Lowe in June the same year where they took over responsibility for the agency's digital offering.
Collinson-Jones will work directly into David Golding, the planning founder, and has been brought in to add weight to the agency's planning department.
She has worked at Fallon since 2004 and covered accounts including Sony, Orange and Skoda.
