An Ordnance Survey 1:2,500 map from 1874-75 shows the location of the George IV marked with the letters 'PH'.

The 1901 census data list a licensed victualler, his wife, mother, three sons, daughter and niece as the occupiers of 144 Brixton Hill.

The 1911 census[6] showed 144 Brixton Hill as the George IV, with the same head of household as in 1901, and a total of 11 people living in the property.

[14] During the early 2000s, the George IV had three main areas: a patio garden at the front, with around ten pub table-benches; a front room with a traditional, oval-shaped wooden bar in the centre; and a room at the back with DJ decks, huge speakers, and a dry-ice machine.

[15][16] Basement Jaxx attribute a significant part of their style to their formative times at the George IV; Simon Ratcliffe explained that the venue is "where our chaos comes from... there was always feedback, records jumping, things going wrong—but people cheered 'cause there was a real vibe; it wasn't clinical".
