Augustus Welby Northmore Pugin and John Hardman[1] undertook the design and execution of the chancel roof.

St Saviour's was built for the poorer people who could not afford this charge,[1][5] and it came to be described as "a little church for the poor".

[3] The main windows of the church have tracery in the Flowing Decorated Gothic style of the early 14th century, that at the east of the chancel being the largest with three lights.

[3] Inside the church the nave is separated from the aisles by arcades of four bays supported on alternate round and octagonal piers.

These include the pipes, the wall brackets, and on the top of the chancel screen, a burner bar consisting of a row of gas jets.
