Benenden Hospital has been a key outlet for specialist medical care since it opened in 1907 to treat postal workers suffering from tuberculosis. By 1951 the Association had disbanded, and the Benenden Healthcare Society took over the sanatorium, expanding treatment to include chest complaints and cancer.

Today the Benenden Healthcare Society is known as Benenden Health. Benenden Health offers a range of discretionary healthcare and well-being services to individual and business healthcare members.In 2017 a multi-million-pound redevelopment of Benenden Hospital opened to patients. This included the construction of a light and bright atrium, a new outpatient area, new CT, MRI, and diagnostic imaging facilities, a new physiotherapy suite, and a spacious Pavilion restaurant. With the central atrium designed to aid healing, with natural light flooding the room, and murals by local photographer, Hugh Turvey, decorating the walls.
