We take the security and safety of our festival-goers very seriously – it is a real priority.

Please help us by bringing as little as possible and remember we do not allow bags larger than A4 into the arena. Please be patient while we carry out our security checks and searches, which take place at point of entry to the event.

Our security staff are there for your safety – please co-operate with them as they work to keep us all safe and sound. Some are covert, but most are obvious by their numbered tabard. Always go to them if you need help.


Please note this event is no re-admission. Please ensure you have everything you need before entering.
