If you are new to the event organising scene, the first port of call should be with the local council within whose boundaries you will be hosting your festival, show, fair etc. No point getting excited about hosting an event and planning it, if the local council says no, and for a very valid reason! Local councils are very keen for you to host only a good, safe event, in their area.
If you want to serve or sell alcohol, provide late-night refreshment, or put on regulated entertainment, you’ll need to complete a License application. It is very important you understand the difference between the two types of license and the length of time it takes for them to be issued.

If you are unsure which is best for you, simply contact your local council who will give you the right information.
We've seen events cancelled at the last minute or Exhibitor traders turned away due to not having the right license in place. This is about safety and the local emergency services, through these licenses, are informed well in advance of your event, mainly so they have your event on their radar and can plan their emergency cover - just in case.
