Returning to the main body of the church and turning east, six steps of white Italian marble lead from the nave to the chancel. The altar step is of the same stone. The carved wooden roof above the altar, set with emblems of the Passion, was supplied by Martyn & Co., Bond Street. The choir stalls and priest's stalls were made by Scott Morton & Tynecastle in Edinburgh.
The east window by Louis Davis, Pinner, Middlesex (1913) shows the annunciation and nativity. It was presented to the church as an anonymous thank-offering. The north window by Mrs Pritchard of Glasgow (1958) was dedicated in memory of Bishop Wilson, who was the first rector of All Saints'. The left light depicts Christ calling Peter and Andrew to be fishers of men, and the right, Peter and John healing the lame man at the Gate Beautiful of the Temple.
The organ, a two-manual and pedal organ, was built by Hill & Son, Norman & Beard, of London, and the case by Nathaniel Hitch.
