St Andrews is a flint church with nave, chancel and W tower. The tower is round in its lower part, which has a pointed lancet of c.1200 to the S and an inserted W window of c.1320. The upper part of the tower is octagonal with Perpendicular bell-openings on the cardinal faces and flushwork tracery on the others, and a battlemented parapet decorated with flushwork tracery. The nave has a 12thc. N window and 12thc. doorways to N and S, the N plain and blocked; the S more elaborate and protected by an early Tudor brick porch. It has been heightened and given Perpendicular windows. The chancel has one 13thc. lancet but otherwise appears 14thc. or later. Nave and chancel are separately roofed but there is no chancel arch. Wall paintings in the nave are currently under restoration. The only Romanesque features described here are the two nave doorways.

The Domesday Survey does not allow us to distinguish between the four Ilketshall parishes. There were many holdings in that name, all but one among the lands of Earl Hugh, and one of these included a church with 20 acres of land. The exception was a parcel of 30 acres among the lands of Godric the Steward. Sir Gilbert de Ilketshall was lord of the manor that included St Andrew's in the reign of William Rufus, and it stayed in the family until the 16thc. when the line died out. The rectory was granted to the nuns of Bungay in the reign of Henry II, and they retained the tithes and advowson until the Dissolution.

Parallels for the S doorway are found at Henstead; similar chamfered block capitals on the N doorway, and chevron of the same profile on the S doorway.
