The retailer, as part of plans to strengthen its marketing activity, has also created three senior head of marketing roles, and is recruiting brand experts in an expansion of the department.
Inglis, who was previously head of brand communications at John Lewis, will continue to report to merchandise director, Jill Little.
He joined the department store chain in 2008, having previously worked at Virgin Trains as sales and marketing director.
The appointment marks a turnaround for John Lewis, which cut back its marketing department last year.
In March 2009, marketing director Gill Barr left the company as part of management cutbacks.
Miranda Goodenough, head of direct marketing, also left the company, with the direct marketing team merging into the brand communications team.
Over the Christmas period, John Lewis reported sales increases of 12.7% on the previous year, citing its Christmas campaign, created by Adam & Eve, and the relaunch of its customer proposition ‘Never Knowingly Undersold' for the positive growth.
