St Andrew's is basically a Norman church that was extended in the 14thc. and 16thc. The church may have been cruciform, with an aisleless nave, and a three-bay S arcade was added in the 12thc. On the N the aisle windows are early 14thc., so an arcade of some form must have been present by then. In the 16thc. a fourth bay was added to both arcades at the E. The central vessel between the arcades is notably wider in the E bay, and the lines of the arcades have been modified to compensate, apparently in the 1870-72 restoration. On the N side the original arcade was entirely replaced with a copy of the 12thc. S arcade to effect a smooth transition, but on the S only the easternmost Romanesque bay was replaced, and this doglegs to meet the Perpendicular E pier. The S aisle windows have Y-tracery of c.1300, and at the W end of this aisle is the tower, of similar date and with a broach spire. The chancel and its arch are Perpendicular, as are the large chapels to either side of it, with three-bay arcades to the chancel and broad arches to the nave aisles. The restoration was by W.J. and G.A. Ashdown of Liverpool (1870-72). The church is of greyish pink sandstone ashlar.
