The PCC is the executive body of a Church of England parish. It consists of the clergy and churchwardens of the parish, together with a number of representatives of the laity elected by the annual parochial church meeting of the parish. Its powers and duties are defined by certain Acts of Parliament and other legislation, principally the Parochial Church Councils (Powers) Measure 1956. It has the responsibility of co-operating with the incumbent (rector, vicar or priest) or priest in charge in promoting the mission of the Church in its parish.

Formally, the PCC is responsible for the financial affairs of the Church and the care and maintenance of the church fabric and its contents. These latter responsibilities are executed by churchwardens. It also has a voice in the forms of service used by the church and may make representations to the bishop on matters affecting the welfare of the parish.
