The site was purpose-built for radio in 1955 and has never broadcast any television services, as these came from Crystal Palace and now also Bluebell Hill.

Wrotham is also home to the NGW maintenance team which takes care of both tv and radio transmitters across the South-East.

In addition to the five national FM services Wrotham also transmits the BBC local station for Kent. At one time it also broadcast BBC Radio London on 95.3 MHz. In a reshuffle of frequencies in preparation for the introduction of ILR in 1972 Radio London's frequency changed to 94.9. Later the station became GLR and its transmissions were transferred from Wrotham to Crystal Palace.
