The first condition is that the whole of the premises is used as a private dwelling and the occupier has been informed of the decision to apply for a warrant.
The second condition is that any part of the premises is not used as a private dwelling and that each of the following applies to the occupier of the premises—
he has been informed of the decision to seek entry to the premises and of the reasons for that decision;
he has failed to allow entry to the premises on being requested to do so by an inspector or a constable;
he has been informed of the decision to apply for a warrant.
The third condition is that—
the premises are unoccupied or the occupier is absent, and
notice of intention to apply for a warrant has been left in a conspicuous place on the premises.

it would defeat the object of entering the premises, or
entry is required as a matter of urgency.
