[1][2] The TWSI is a registered charity,[3][4][5] entrusted to use its property "as an Institute providing for the use of its members the means of social intercourse, mutual helpfulness, mental and moral improvement, rational recreation, and the other advantages of a Club" for ex-servicemen, their families, and vulnerable members of the wider community.

From 1995 to 2012, the building's top floors housed an annex of the nearby Tottenham police station.

Supported by the Reknaw sound system, T. Chances has gained a profile as one of London' major punk rock venues.

[8][9] Notable figures associated with T. Chances included the musician Captain Rizz, and the poet Xochitl Tuck, who ran regular Survivors Poetry nights at the venue until her death in 2012.

[10] As of 2020, the TWSI began operating out of the county of Somerset (South West England), [11] stating on the register of charities held by the Charity Commission of England and Wales: "In 2020 trustees made the decision to move from a London hub to participate in other parts of the country".
