Unless previously revoked under subsection (4), a designation ceases to have effect at the time that is specified for this purpose in the designation.
That time must be no later than five years after the date on which the designation comes into force.
A local housing authority must from time to time review the operation of any designation made by them.
If following a review they consider it appropriate to do so, the authority may revoke the designation.
If they do revoke the designation, the designation ceases to have effect at the time that is specified by the authority for this purpose.
On revoking a designation the authority must publish notice of the revocation in such manner as is prescribed by regulations made by the appropriate national authority.
