"The church is an example of early 14th century Decorated style with a 172 feet (52 m) spire.
In the north chancel is the recumbent effigy of Sir Alexander Aunsell (d. 1360), the founder of the church.
St Andrew's was restored in 1895.
In late 2009 the ecclesiastical parishes of Kirkby Laythorpe and Ewerby became part of the benefice of New Sleaford, to be held in plurality"
