The dedication to St Thomas has been disputed; J. Charles Cox refers to a dedication to St Peter. It was originally called St Thomas of Canterbury, but it would appear it was briefly changed to St Peter, but has reverted to its original name.
In the churchyard is the lower part of a 14th-century Grade II listed and scheduled churchyard cross.
^Cox, J. Charles (1916); Lincolnshire, Methuen & Co. Ltd., p.233: "The large church (St Peter) is in the main a good example of E.E. It has a massive W. tower, a beautiful S. door-way enriched with dog-tooth moulding, and nave arcades of 4 bays with capitals of stiff conventional foliage. The chancel was rebuilt in 1874."
