The club runs three senior sides[1] and the first XV currently play in Regional 1 South Central following their promotion from London 1 South as champions at the end of the 2017–18 season.

[2] At what point the Civil Service Rugby Club became a distinct entity from the association football is unclear.

Certainly, the histories published by the official Football and Rugby clubs respectively do not refer to a joint history past even 1863.

However, the club was still a unified entity when it became a founding member of the Rugby Football Union in 1871,[2] although notably it did not provide a member to the inaugural committee.

However, in 1892 contemporary sources refer to Clapham Rovers as being unique in the respect that it played both codes, suggesting that the Civil Service had distinct teams by that point.
