Trades are divided under the Czech Trades Licensing Act (Act No. 455/1991 Coll.) into notifiable trades,
which can be obtained based on notification, and concession trades, which can only be pursued on the
basis of a special business licence – a concession. Notifiable trades are categorised into three further
groups: vocational, professional, and unqualified.
