The Dungeness Estate has been purchased by the French-owned energy company, EDF Energy.
The sale of the estate was announced in August when property agents advertised it on the open market with a price tag of £1.5m.
The 468-acre estate is designated as a National Nature Reserve, a Special Area of Conservation and a Site of Special Scientific Interest.
EDF Energy owns and operates Dungeness B nuclear power station, adjacent to the estate, and is the biggest employer in the area.
Legal completion will follow in line with the agreed contractual arrangements and EDF Energy will be responsible for managing the land only following legal completion.
