In most cases the premises on which the event will be held must have a current premises licence under the Licensing Act 2003. Under this act certain short-term, small-scale events may be held, provided the organisers send a Temporary Event Notice to the local licensing authority and the police 10 working days before the event. Depending on the type of event you are running, you may also need to contact your local authority, the police or local ambulance service too.
Licences cover the supply and sale of alcohol, the performance of various types of regulated entertainment (including live or recorded music), and the supply of hot food and drink late at night. Guidance is available from the Department of Culture, Media and Sport.
