AEO is part of EIA
AEO, AEV and ESSA are the three parts of EIA, whose members collaborate and support the events community.
AEO works in partnership with its sister associations on a number of initiatives including research, cross association working groups and lobbying.
This enables the event community to come together as one voice, responding to a range of opportunities or issues into which all sides of the industry have an important input.
It also enables members access to several cross-association working groups, networking events, conferences, forums and industry research.
The alliance gives us and our members the opportunity to influence key initiatives and changes that can have a direct impact upon the whole sector.
Association of Event Venues (AEV) is a vibrant, effective and highly professional trade body that serves an established event venue community.
Event Supplier and Services Association (ESSA) is a trade association representing contractors and suppliers of goods and services to the exhibition industry.
MARTYN'S LAW
Martyn’s Law is proposed UK legislation designed to enhance security at public venues and events by requiring organisers to implement measures to protect against terrorist attacks. Understanding Martyn’s Law is crucial for preparing for these changes, as it aims to improve safety for attendees and staff, and may require modifications to current security practices.
