The Diocese is divided into two Archdeaconries each headed by an archdeacon with a number of smaller deanery units within them.
Archdeaconries are the principal sub-division of dioceses for administrative and judicial purposes and date from the twelfth century.
Archdeacons, as the senior Bishop's Officers, have responsibility for the care of the clergy and church communities within their Archdeaconry.
- The induction of churchwardens.
- Legal powers to give permission via the Church's own Planning Permission system (Faculty Jurisdiction), for work on the repair and ordering of church buildings.
- Responsibility for the checking of parish records and church valuables.
- In the Ely diocese, the responsibility for the practical and legal issues relating to the appointment of clergy.
- Working with others in pastoral re-organisation, clergy housing and occasionally with disciplinary matters.
