Any business licensed to sell alcohol, including small pubs, retailers, large night clubs, cafés, restaurants, hotels and sports facilities, is required by law to have at least one personal licence holder. 
To become a personal licence holder, an individual should obtain a regulated personal licence holders qualification.
A personal licence allows the holder to sell or authorise the sale of alcohol.
A personal licence is also needed to apply to become a designated premises supervisor (DPS). Licensed premises can have more than one personal licence holder.
