[3] The church is listed Grade II and is notable for its stained glass windows and mosaics lining the walls, and especially the reredos.

Details of the correspondence between the firm and Hansom, and the prices paid for the windows, are taken from Hardman's records, now held in the Birmingham City Archives.

The date of the East Window is not known, but Julian Small presumes that it was made at the same time as the rebuilding of the church, in 1868, as it is above the altar and would have been, as now, part of the focus of attention of the congregation.

In a letter dated 12 October 1868, Hansom wrote to Hardman's requesting that a sketch was made and an estimate of price: Apparently the glass removed remains in the crypt of St Paul's today.

The windows on the North side of the church are the most recent depicting the Raising of Lazarus, from 1887, and Christ walking on water.

The West Window, above the main entrance to the Church, was donated by a Major General Fitzgerald, HM Indian Army.

A brass plaque on the pillar on the north side of the door reads The records held in the Birmingham Archive show that Hardman's were not always punctual in delivery, and General Fitzgerald refused to pay the bill for the windows until alterations had been made and he had been supplied with a drawing of the design.

The mosaics of St Paul's are a collection of 11 opus sectile works, lining the nave and in the reredos, produced by James Powell & Sons of Whitefriars, London.

Through the project, St Paul's has established a Choral Scholarship Programme, Children's Choir in East Bristol, Singing for the Brain group, Lunchtime Concert Series, and a number of community focused music events.
