Large Conference Venues in London
Organising a large conference in London comes with a very different set of requirements to planning a smaller event. Once delegate numbers reach several hundred or even 1,000+ capacity is only the starting point. You may also need a large auditorium or plenary room, multiple breakout spaces, substantial AV and production facilities, efficient registration areas, exhibition space and catering that can comfortably handle high numbers.
London has an exceptional choice of large conference venues, from purpose-built conference centres and major hotels to universities, exhibition venues and impressive spaces for high-profile corporate events.
At Best Venues London, we understand the practicalities of finding venues for large-scale conferences. We’ll consider delegate flow, room capacities and layouts, technical requirements, accessibility, transport links, accommodation and, importantly, your budget.
