Wormington was an ancient parish, and became a civil parish in 1866, but on 1 April 1935 the civil parish was abolished and merged into the parish of Dumbleton. On 1 April 2023 it became a parish again. The parish is governed by a parish meeting.
St Catherine's parish church is reputed to have been built in 1475 by the abbot of Hailes Abbey on the site of a 12th-century church. It is a Grade II* listed building.
Wormington Grange, a mile south of the village but just over the parish boundary in the neighbouring parish of Stanton, is a Grade II* listed country house.
