Your Guide to Large Conference Venues London (500+ Guests) in london
Scaling up your event to 500+ delegates changes the game. You move from simple meeting logistics to complex crowd management, where the flow of people is just as important as the content on stage. London’s landscape of large conference venues is diverse, offering everything from blank-canvas warehouses in East London to chandeliers and marble in the West End.
At EventCage, we understand that for large events, infrastructure is everything. You need a venue that can feed 500 people in 60 minutes without long queues, cloakrooms that don't cause a bottleneck at 9am, and Wi-Fi that can handle hundreds of simultaneous connections. Our curated list highlights venues that excel in these operational details, ensuring your summit or AGM runs seamlessly.
When choosing a large venue, consider the "plenary-to-breakout" ratio. Many venues have a massive main hall but lack sufficient nearby rooms for workshops. We recommend venues like **etc.venues Houndsditch** or **The Mermaid London**, which are designed specifically to keep large groups contained yet comfortable, with breakout spaces immediately adjacent to the main stage.
