Sedgebrook is mentioned in the 1086 Domesday Book as Sechebroc in the wapentake of Winnibriggs. The name Robert Malet and three mills are noted. Sechebroc means "Brook where sedge grows", from OE secg "sedge" and brôc "a brook" The parish church of St Lawrence is a largely 15th-century building with an early 13th-century north arcade and a 14th-century chancel arch. A pamphlet history of the church appeared in 1980 and was republished in 1990. The church is the only Grade I listed building in the village. Sedgebrook Manor House is Grade II* listed, and three other houses and three architectural features are Grade II. The church shares a priest with Foston, West Allington and Long Bennington. The Grantham Canal passes south-west of the village. It opened in 1797 but closed in 1936. A voluntary society formed in 1969 has restored parts of the canal for recreational use. The towpaths form a long-distance walk, as does the Viking Way, passing about to the west of the village, known here as Sewstern Lane. Newbo Abbey was sited between Sedgebrook and Barrowby in the 12th century. The wartime RAF Bottesford airfield lies north-west of the village.

Education
Sedgebrook had its own primary school up until 1981, when the building was closed and the school amalgamated with that of Allington. Sedgebrook also had at one time a grammar school. This was erected in 1882, and in 1908 there were 75 boys attending. By 1913 it was a secondary school for the surrounding area. It was absorbed into The King's School, Grantham, probably in 1919.
