Karen Dukes and Mark Shires of PriceWaterhouseCoopers were appointed administrators on 4 January after the business ran into financial difficulties.
The hotel's owners, general manager Andrew Russell and head chef Mark Raffan, who bought the hotel in 2004, had faced issues with the bank after the recession led to a drop in business and said they had no option other than going into administration.
A spokeswoman for PWC said it was 'business as usual' at the 18 bedroom hotel with staff jobs to remain and all bookings honoured until a buyer is found.
"We are looking for a buyer and have had some expressions of interest. It's a well regarded boutique hotel so we should not have any problem selling it on," she said.
Gravetye Manor, a Relais et Chateaux hotel, was turned into a hotel in 1958 by hotelier Peter Herbert. Russell and Raffan both worked for Herbert and his family for 17 years each before buying the business.
