The parish’s first pipe organ (1-manual and pedal) was built for the temporary church building by the firm of Henry Jones. It was later moved to the church of St Alphege Edmonton. The present 3-manual instrument was installed in 1908, built by the Norwich-based firm of Norman and Beard. As a mark of the importance of the St Stephen’s organ to the nation’s heritage, being of special interest and warranting every effort to preserve, it has been awarded an Historic Organ Certificate by the British Institute of Organ Studies, the amenity society for the British organ, which lobbies Government, Historic England and other national bodies.
The original cost of the present instrument was £1,150. The imposing carved organ case is a gift from the first vicar, Edward Forbes (1863-1941), as a memorial to his father.
