The church has a 12thc. nave and 13thc. chancel.
In 1086 Udimore, in the Rape of Hastings, was held by Reinbert from the Count of Eu. A church was mentioned.
A fragment of a shaft carved with spiral fluting, perhaps from a pillar piscina, was reported to be in the porch by the VCH (1937) and Pevsner (1965). It is no longer in the church and is not known to present incumbent. No illustration known.
