The hotel will continue to be run by managing director Craig Bancroft and general manager Craig Jackson, with executive chef, Lisa Goodwin-Allen.
Former chef patron and shareholder Nigel Haworth resigned as director in late 2017 but remains as chef ambassador to the business.
Northcote is a member of Pride of Britain and Relais & Chateaux. It was named the AA Hotel of the Year for England 2016-17. The restaurant was awarded a Michelin star in 1996 under then chef-patron Nigel Haworth.
