Large conferences require ample space. Evaluate the capacity of each venue, keeping in mind the number of attendees you expect. Additionally, inquire about the flexibility of the space, as some venues offer customisable layouts to accommodate various event formats.

Technology and AV facilities:

Event planning support:

Many conference centres in London provide dedicated event coordinators to assist with planning and logistics. Take advantage of this support to streamline the organisation of your event, from initial booking to on-the-day coordination.

Request detailed quotes from potential venues, including rental fees, additional services, and any hidden costs. Negotiate where possible and be transparent about your budget constraints. Some venues may offer package deals or discounts for certain days or times.
