A listed building consent order or local listed building consent order may include provision permitting the completion of works if—
listed building consent is granted by the order in respect of the works, and
the listed building consent is withdrawn after the works are started but before they are completed.
Listed building consent granted by an order is withdrawn—
if the order is revoked;
if the order is varied or (in the case of a local listed building consent order) revised so that it ceases to grant listed building consent in respect of the works or materially changes any condition or limitation to which the grant of listed building consent is subject;
if a direction applying to the listed building is issued under powers conferred under section 26C(5) or 26D(6).
