While London is undoubtedly one of the areas that is first considered when hosting a large conference, the lack of a large enough venue can put off many people. This is particularly the case where the number of attendees exceeds 5,000 people at any one event. There is a dearth of venues that can accommodate that number of people in a conference situation, let alone the additional facilities that would be needed. The number of conferences with that number of people is increasing each years and a city that is unable to cater for that can become less popular as a venue for conferences. This is why the new ICC has been proposed for London.

There has been a lot of debate about whether the ICC is really needed and what impact it can have for the city. The feasibility study was undertaken and the result showed that the centre would give great benefit to the city as a whole. These benefits could directly affect the accommodation industry, the tourism industry and a host of related industries. The new conference venue will be able to offer facilities that are otherwise inaccessible for people hosting conferences in London. The attraction of London as a premiere destination for conferences will be enhanced through the new facilities that will be available at the ICC.

The capability to host over 5,000 delegates will be one of the biggest advantages of the new ICC in London. The largest area can be used for hosting the main events of the conferences while the smaller areas can each serve different purposes. To help increase the productivity of the conference, there will be rooms known as 'breakout' rooms for people to utilise during the course of the conference. These will each have different have different capacities so that different sized groups can all be accommodated. This allows small, related meetings and events to take place in tandem with the main events of the conference.

There will also be large meeting rooms capable of holding a few hundred people for smaller events in the conference to be hosted. This will allow a greater number to attend conference events than if there was only a single auditorium. This can allow multiple different conferences to take place at one time, depending on size of each of the different conferences. The facilities that are available will help to provide delegated with catered events, which is often impossible in other facilities. The situation of the ICC in London means that a range of different accommodation will be available in the immediate area so that transport for delegates will not be a problem. The situation of accommodation on the site will also help to reduce travelling and logistics problems for those attending the conference as well as those that plan the conference.
