The planning was previously handled by Burkitt DDB, while the buying was handled by OMD.
The review was kicked off following John Lewis's decision to move its £13m creative account to Lowe London from Burkitt DDB.
The media review was handled through the media consultancy, Billetts.
Manning Gottlieb OMD already handles John Lewis retailer Waitrose's £9m media planning and buying business. The account was awarded to Manning Gottlieb OMD in June.
Evelyn Strouts, head of advertising at John Lewis, said: " All the agencies were strong. In the end we decided on MG/OMD because we felt the chemistry fit was the strongest, their service levels were so high."
Phil Nunn, executive director at Manning Gottlieb OMD, said: "[John Lewis] are a fantastic fit for the Agency and the chemistry between the teams has been second to none. We can't wait to get stuck in."
