 The station was renamed "Chalfont & Latimer" in 1915, although station signage was inconsistent and on absorption by London Transport in 1933 its roundel signs read simply "Chalfont". Increased passenger numbers strained the station's minimal facilities, and it was eventually redeveloped with extended shelters and improved waiting rooms in 1927. The platforms were extended during the electrification works of 1957 – 60.
