Throughout the United Kingdom, the sale of alcohol is restricted—pubs, restaurants, shops and other premises must be licensed by the local authority. In England, Wales and Scotland the authority to sell alcohol is divided into two parts – the Premises Licence, which prescribes the times and conditions under which alcohol can be sold, and a Personal Licence which allows individuals to sell alcohol or authorise its sale by others. Every Premises Licence which authorises the sale of alcohol must also name a Designated Premises Supervisor (Designated Premises Manager in Scotland) ("DPS" or "DPM" for short) who must hold a valid Personal Licence – otherwise alcohol cannot be sold at those premises. The DPS has day-to-day responsibility for the sale of alcohol at licensed premises. Premises licences, in as far as they concern the sale of alcohol, can be categorised to include "on-licences" (allowing consumption of alcohol on the premises) and "off-licences". However, these distinctions are not explicitly made in the Licensing Act 2003, and the position in Scotland and Northern Ireland is more complex. Many on-licensed premises also permit off-sales.
