Works to which section 11 applies are authorised if the works are within a class of works described in the table in Schedule 3.

An authorisation under subsection (1) is subject to any exceptions or conditions specified in the table in relation to works of a particular class.

The Welsh Ministers may direct that subsection (1) does not apply to any scheduled monument specified in the direction.

A direction under subsection (3) does not take effect until notice of it has been served on every owner and occupier of the monument in question.

Subsection (1) does not authorise works contrary to any exception or condition attached to a scheduled monument consent.

An authorisation under subsection (1) has effect for the benefit of the monument and of all persons for the time being interested in the monument; but this is subject to any provision to the contrary in Schedule 3.
