The Walker organ, which has two manuals and 21 stops, was installed by D. J. Miller, organ builder of Orwell, Cambridgeshire, in 1982. The organ was made playable but not completed, because funds ran out. This work has now been resumed and when complete, the specification will include 31 speaking stops with solid state action transmission and a capture system for stop management. There was no organ case to salvage from Hatcham, and the present fine case was designed by local architectural designer, Charles Morris FRICS, a member of this church, who explains that the painted finish was chosen to blend more softly with the surrounding stonework.

The geometry of the nave facade was carefully devised so as to reflect but not counteract with the stone arcading. The two 'arms' might be said to signify the outstretched arms of Christ on the cross with the central opening the crown of His head. It is proposed to place trumpet pipes en chamade within this opening, which will represent respectively the Voice of God and the Light of Life. The interlaced decoration unfolds, as might a fugue, starting with a circle and developing into entwined hearts which repeat at the base where the single form in the fish - the earliest Christian symbol.
