The parish council has responsibility for local issues, including setting an annual precept (local rate) to cover the council's operating costs and producing annual accounts for public scrutiny. The parish council evaluates local planning applications and works with the local police, district council officers, and neighbourhood watch groups on matters of crime, security, and traffic. The parish council's role also includes initiating projects for the maintenance and repair of parish facilities, as well as consulting with the district council on the maintenance, repair, and improvement of highways, drainage, footpaths, public transport, and street cleaning. Conservation matters (including trees and listed buildings) and environmental issues are also the responsibility of the council.

For local government purposes, since 1 April 2023, the parish comes under the unitary authority of Somerset Council. Prior to this, it was part of the non-metropolitan district of Somerset West and Taunton (formed on 1 April 2019) and, before this, the district of West Somerset (established under the Local Government Act 1972). It was part of Williton Rural District before 1974.
