Throughout this time, Moseley was regarded as a Perpetual Curacy, with trustees looking after it, and a Chapel of Ease first to Bromsgrove and then to King's Norton churches. As a result of augmentations to the living from Queen Anne's Bounty during the 18th century, Moseley became an ecclesiastical parish (‘body politick’) in its own right, but without a defined boundary, in 1755. By 1780 the Chapelry of Moseley was described as a very ancient structure the middle aisle of which was falling down and all other parts except the Tower were so ruinous that it could no longer be supported and "not being large enough to contain the inhabitants that resort thereto must be taken down rebuilt and enlarged before divine service can be performed therein with Safety to the Minister and Congregation". A public subscription was sanctioned by Letters Patent of George III to secure the architect's estimated cost of rebuilding of £1028.5s.10½d., excluding old materials.. The chapel was widened and the height was raised by about 8 feet. In 1823, with the benefit of a grant of £250 from the Incorporated Society for the Enlargement of Churches and Chapels towards the total cost in the region of £2000 raised by another public subscription, Thomas Rickman (1776–1841) was chosen as the architect to improve the building with his ideas of Gothic Revival but it was all sham. The walls were brick, plastered inside and out in imitation of stone; the flat ceiling was crossed by parallel and diagonal imitation oak beams in plaster and the window mullions were cast iron. Even the font was a plaster bowl fixed against the west wall, modelled on a medieval piscina. Everything had to give way to accommodation for an additional 362 seats of which 247 were free. This church was about the length of the Nave of the present church. There was no Chancel, but rather an apse for the altar at the East End. Against the tower at the West, there was a loft, accessed from the belfry, which housed a small barrel organ and choir. This instrument produced a very small selection of hymn tunes (probably only 6) and a short-lived music group was introduced to enhance the music but it was found to be too expensive to maintain. Miss Sarah Taylor of Moseley Hall then provided the church with a new, much improved barrel organ in 1838, the loft having been converted into a larger gallery with seating for about 150.
