A Chartist Church in Deptford

One strand of the radical Chartist movement was Christian Chartism, some of whose adherents created their own churches which put into practice the democratic principles of the movement. One such church was in this area; according to Mark Hovell's book The Chartist Movement, 'at Deptford there was established a "Working Men's Church," whose members were said to study the New Testament in Greek' (his source is the Chartist paper, Northern Star, October 30 1841). I wonder where this was?
