The De Vere Group has secured East Sussex National through a management contract, following the news in April that De Vere Venues is up for sale for an estimated £280m.
The venue has 100 bedrooms with capacity to host between 8 and 400 delegates across 10 meeting and conference spaces.
The property is set in 1,110 acres of Sussex countryside with views of the South Downs. It has outdoor space for team building events and has two Championship Golf Courses, which have staged European Open events.
The venue is 20 minutes from Brighton and 40 minutes from Gatwick Airport and London.
Tony Dangerfield, CEO of De Vere Venues, said: "East Sussex National is a real asset to De Vere Venues expanding property portfolio and we’re delighted to welcome them on board. The facilities, including the championship golf courses are second to none and we’re looking forward to welcoming delegates through the doors."
Michael Hunt, the owner of East Sussex National, said: "De Vere were chosen ahead of other candidates because of their flexibility in adapting their requirements to suit the existing culture of each individual hotel and their emphasis on staff training and customer satisfaction."
During the first six months of 2013, De Vere has added five venues to its portfolio, including Heythrop Park, Chicheley Hall, Kassam Stadium, Studley Castle and Altitude London.
Tony added: "The new venues coming on board prove testament to our on-going growth strategy and our commitment to providing delegates with a diverse and varied selection of properties across the UK."
