From 20th December 2016 if you intend to have a field meeting you must follow certain conditions. Currently you don’t require a licence but you must follow new APHA guidance.
You must notify APHA at least 7 days before a meeting and provide them the following details:

You must keep good and accurate records of the field meeting for at least 3 months, including:
