Church consists of three-bay nave with side aisles, clerestory, W tower, chancel, a N chapel off the chancel, and S porch. The N aisle is of the early 14thc., the clerestory, first two stages of the tower, chancel, and S porch are all of later 14/15thc. date. Restorations by G.G. Scott in 1844-45 and Temple Moore in 1895-96. The S aisle arcade is Romanesque and there is a 'Neo-Norman' font.

Hougham fell in with the lands owned by Bishop Remigius of Lincoln in 1086; besides land he owned the manor here as well. At that time, the Domesday Survey records a church and a priest in the village. Robert the priest, who in 1086 was a monk in St Mary's, Stow, owned one carucate of land in Hougham

It is clear from the remaining wall portion between bays 2 and 3 that originally the nave here consisted of just the first two bays, probably without any aisles.
