(2) Admission to any premises used only as a private dwelling house may not be demanded as of right unless 24 hours' notice of the intended entry has been given to the occupier, or the entry is in accordance with a warrant granted under this paragraph.
(3) If a justice, on receipt of sworn information in writing, is satisfied that there are reasonable grounds for entry onto any premises for the purposes of the enforcement of these Regulations, and either–
(a)admission has been refused, or a refusal is expected, and (in either case) that notice to apply for a warrant has been given to the occupier;
(b)asking for admission, or the giving of such a notice, would defeat the object of the entry;
(c)the case is one of urgency; or
(d)the premises are unoccupied or the occupier is temporarily absent,
