The police and local authority exercising environmental health functions may intervene on the grounds of any of the four licensing objectives (the prevention of crime and disorder, public safety, the prevention of public nuisance, and the protection of children from harm) to prevent the occurrence of an event at which permitted temporary activities are to take place or to agree a modification of the arrangements for such an event. However, the licensing authority will intervene of its own volition in the cases described below.

First, it will issue a counter notice if there is an objection to a late temporary event notice (see note 7 below).

Secondly, it may issue a notice in relation to its decision to impose conditions on a temporary event notice (see note 2 below).

Thirdly, it will issue a counter notice if the first, second and fourth of the limits set out below would be exceeded. If any of the limits below are breached or if a counter notice has been issued, any licensable activities taking place would be unauthorised and the premises user would be liable to prosecution. The limitations apply to:

• the number of times a person (the "premises user") may give a temporary event notice (50 times per year for a personal licence holder and 5 times per year for other people);
• the number of times a person (the "premises user") may give a late temporary event notice (10 times per year for a personal licence holder and 2 times per year for other people);
• the number of times a temporary event notice may be given in respect of any particular premises (12 times in a calendar year);
• the length of time a temporary event may last for these purposes (168 hours);
• the maximum aggregate duration of the periods covered by temporary event notices at any individual premises (21 days per calendar year); and
• the scale of the event in terms of the maximum number of people attending at any one time (a maximum of 499).

For the purposes of determining the overall limits of 50 temporary event notices per personal licence holder (in a calendar year) and of 5 for a non-personal licence holder (in a calendar year), temporary event notices given by an associate or a person who is in business with a premises user (and that business involves carrying on licensable activities) count towards those totals. The limits applying to late temporary event notices are included within the overall limits applying to the total number of temporary event notices. Note 14 below explains the definition of an "associate".In addition, where the premises are to be used primarily or exclusively for the sale or supply of alcohol for consumption on the premises, it is an offence to allow children under 16 to be present when the premises are open for that purpose unless they are accompanied by an adult. In the case of any premises at which sales or supplies of alcohol are taking place at all, it is an offence for a child under 16 to be present there between the hours of midnight and 5am unless accompanied by an adult. In both instances, the penalty on conviction is a fine not exceeding level 3 on the standard scale, currently £1,000.
