No determination or redetermination shall be made if the application for it is withdrawn.

No determination shall be made under paragraph 3, 4 or 5 of Part I of Schedule 1 if the tenancy is of residential accommodation, within the meaning of regulation 7(3) of the 1987 Regulations8, or in a hostel.

No determination shall be made under paragraph 5 of Part I of Schedule 1 unless the local authority states in the application that the claimant is, or may be, a young individual (which has the same meaning as in the 1987 Regulations9).

If the rent officer becomes aware that an application is not one which gives rise to a duty to make a determination or a redetermination, the rent officer shall give the local authority notice to that effect.
