Alkington was in Thornbury Rural District until the RDC was abolished in 1974. The greater part was transferred into the new county of Avon, as part of the new district of Northavon but a group of parishes in the north of the district, around Berkeley, wished not to transfer into the new county, but chose instead to remain with Gloucestershire, under the new Stroud District Council. These were the parishes of Hinton, Hamfallow, Ham and Stone, Alkington, and Berkeley itself.
With the demise of Avon, in 1996, Alkington remained with the main county of Gloucestershire.
