St Andrew’s has a nave with a north aisle, the plain three-bay arcade dating from c.1200. A north transept was added in 1847 to house a Robinson family pew. The chancel has chapels to north and south; the north now housing the organ, and the south monuments of the Robinsons. The west tower is late-13c in its lower parts, including an elaborate west doorway and the bell-openings. It was heightened and battlements added in the 14c. Only the N arcade is described below. The two Cranford churches were united under a single rector in 1841, and in 1954 St Andrew’s became a chapel-of-ease to St John’s. It passed into the care of the Churches Conservation Trust in 1996.

The manor was held by Robert from the Abbot of Peterborough in 1086, with further small holdings in the hands of Godric (held from the king), and Odelin (held from Guy de Raimbeaucourt). No church or priest was recorded at this time. Despite Peterborough’s holdings here, the abbey never seems to have held the advowson of the church, which was in the hands of the lord of one of the two manors of Cranford by 1240.

Dalton dates both St Andrew’s and St John’s to “the time of King Henry II, when St Hugh of Avalon was Bishop of Lincoln.” If true this would date both churches between 1181 and 1189, which seems over precise in view of the lack of any evidence.
