[1] In 1865 the curate of Holy Trinity, Brompton, the Reverend R. R. Chope, had a temporary iron church put up in his garden off Gloucester Road, and there he would conduct services which, for one writer of the time, were "the nearest approach to Romanism we have witnessed in an Anglican church … if indeed it be not very Popery itself under the thinnest guise of the Protestant name".

[2] As there was no shortage of churches in the neighbourhood, the Bishop of London, A. C. Tait, objected strongly to the proposal and it was not until after he became Archbishop of Canterbury in 1868 that a site was purchased and the new parish formed.

[3][4][5] Unusually, given that HTB is a charismatic evangelical Anglican church, St Augustine's has "kept its Sung Eucharist, vestments and incense".

Clergy from HTB wear albs and coloured stoles appropriate to the liturgical seasons to celebrate the weekly 11 am Sung Eucharist.

[8] A more informal, evening service was also introduced though this now takes place at St Paul's, Onslow Square.
