Heckingham parish sits in south-easterrn Norfolk to the north-east of the market town of Loddon and between there and the ferry across the River Yare at Reedham. The parish consists of a section of marshlands on the east bank of the river Chet, which flows northwards into the Yare, and a low lying but raised area of arable farmland to its east.

St Gregory's church lies down a narrow unsurfaced lane off a maze of narrow surfaced lanes on the edge of the Chet floodplain The churchyard slopes dramatically off to the west onto the grazing marshes with the Norman tower standing proud above the drop . Despite being octagonal the tower is early and the base carries indications of a mid-12th century origin. The thatch gives a certain charm to the nave and chancel. The area is relatively sparsely populated nowadays and probably the parish was always dominated by the needs of the local Hall.
