Georgian period. There was a medieval manor at the south end of the village, now evidenced by remains of the manorial moat. John Sandale, Chancellor of the Exchequer and Bishop of Winchester, held the manor of Great Coates and was granted Free warren there in 1313; Sandale's grant was 'to his heirs for ever' (et heredes sui imperpetuum). Also granted in 1313 was the right to the manor's 'wreckage of the sea and all animals called waifs, found within the said manor' (). In October 1697 antiquary Abraham de la Pryme recorded the moated site in Great Coates as containing a brick built religious house, with "turrits like the old buildings, and somewhat in the walls of the gaithouse, which seems to have been niches for images, tho' now bricked up". In 1821, the parish of Great Coates comprised 171 residents and 46 houses, in 36 houses and 237 residents. The Great Grimsby and Sheffield Junction Railway was constructed , and Great Coates railway station was built in 1848. In the village consisted of the church, rectory (early 19th century, now The Old rectory), a Wesleyan chapel, and around 20 dwellings including the substantial Manor House (), and Great Coates House, as well as with the station less than 1/2 mile northeast of the traditional centre (church and manor site). Outside the village the parish was rural, with enclosed fields and drainage channels, with no other habitations of any significance, excluding Pyewipe farm to the northeast. This development in the parish was mostly unchanged until 1950: the Grimsby and Immingham Electric Railway which passed through the northern part of the parish opened 1912; and terraced housing was built on Woad Lane north and south of the station in the early part of the century. Additionally a biscuit factory (Watmough and Sons Ltd) had been established east of Woad Road, and north of the railway line by the 1930s. Watmough became part of Scribbans and Kemp in 1948 (later known as Kemps Biscuits, and later became part of United Biscuits). United Biscuits closed its factory in 1995, which then employed several hundred people. Today the Original Factory and Site is owned by HSH Coldstores who has developed and modernised the site into a Cold Storage Facility officially known as HSH Coldstores Lewis Howard Avenue. (Lewis Howard Avenue is the name of an internal access road built on the site in 2015).
