The Northern line station was opened in 1890 by the City and South London Railway (C&SLR) while the Bakerloo line station was opened sixteen years later by the Baker Street and Waterloo Railway (BS&WR). There is an out-of-station interchange with the nearby Elephant & Castle National Rail station.

Station buildings

Access to the more northerly (Bakerloo) part of the station is via the original building, while the exit is via a new extension next to Skipton House. Between the entrance and two shops is the entrance to South London House, an office block above the station. The BS&WR station building remains much as originally constructed and is a typical Leslie Green structure. The main alteration is a modern glass-sided and glass-topped flat-roofed extension abutting the original western elevation, giving access to three of the six arches. These arches, in a classic deep-red faience style, formed the original perimeter: two are infilled with street-facing shops. As the station also functions as a drivers' depot, London Underground uses the offices above the station for administration and drivers' accommodation.

The C&SLR station was designed by Thomas Phillips Figgis It was partially rebuilt in the 1920s when the C&SLR tunnels were modernised, and was rebuilt during the construction of the Elephant & Castle shopping centre and roundabout in the 1960s. This Northern line ticket hall was rebuilt at the start of the 21st century, reopening on 12 December 2003 following 2 years of upgrade work.

Neither the Northern line nor Bakerloo line ticket halls have escalators. To get from either ticket hall to the platforms it is necessary to use the lifts or spiral stairs.
