There were nonconformists in the Childs Hill area perhaps from the earliest times. The house of a Samuel Everard in Childs Hill, it seems, was used for such worship as far back as 1672.

Baptists used a house at Childs Hill in 1823, registered a house at the Burroughs in 1831, and built a small chapel in Brent Street in 1832. After 1843 the chapel served as a warehouse until it was taken over in 1845 by the Shouldham Street Baptist Chapel, St Marylebone, which shared it with Congregationalists. In 1851 there were 30 worshippers but attendance dwindled after the opening of Hendon Congregational church and in 1857 services ceased. Another Baptist church, founded at the Hyde in 1843, had closed by 1857.
