The organ was built by George England in1781, rebuilt by Holditch in 1876, and again by Norman & Beard in 1908. It originally stood at the west end above a gallery which stretched across the width of the church. This gallery was taken down in 1876 when the organ was removed to the east end of the north aisle and its case replaced..
There is a handsome doorcase at the west end which is said to have been brought from St Antholin when that church was demolished in 1874.
This is the South door.

The font was given to the church by a parishioner, Dutton Seaman, in 1682. The cover, also given by a parishioner, dates from 1796. The oak rails are probably the original altar rails.
The pulpit similarly dates from the 1680's. It originally had a clerk's desk and a reading desk and was surmounted by a sounding board. These were sold at auction on 1st April 1876 for £7 10 shillings and replaced by the present oak base and marble plinth
The sword-rest or sword-case, which was used to hold the Lord Mayor's ceremonial sword when he visited the church, is now fixed to the third column on the south side of the nave, but was probably removed there from a position on one of the front pews. It is of exceptional quality and craftsmanship and is one of only two wooden sword-rests remaining in the City churches; all the others are made of metal, usually wrought iron.
The choir stalls date from 1876. The marble flooring in the chancel was laid down about 1920. The lectern is of oak and is Victorian. Three only of the original four evangelists on the buttresses now remain.
The altar table has a white marble inlay inscribed with the name of Edward Watts, merchant, and is late seventeenth century. The crucifix and candlesticks on the altar, although in seventeenth century style, date from early this century, and were designed by Sir Ninian Comper. The reredos is in Perpendicular Gothic style and depicts the Marriage at Cana. It is said to have been given by the Rev Bernard Reynolds (Rector 1903-23) in 1914 in place of a Victorian altar piece which in turn had replaced the altar piece donated by the widow of Sir John Smith, Sheriff of London, in 1699.
