Audiences love to be inspired by engaging and insightful speakers. The bigger the audience, the louder the rapturous applause. Of course, great speeches need an inspiring backdrop and a comfortable, spacious room.
Venues in London are plentiful and we have some of the best conference rooms in the city - thoughtfully designed to energise those attending an in-person event. Here are seven of our most impressive conference spaces in central London:

When the blackout blinds are opened, floor-to-ceiling windows on three sides of the room ensure plenty of natural light - and panoramic views - to keep attendees energised.

With two green rooms adjacent to the conference room, there is ample space for speakers to relax and prepare themselves before going on stage.

4. Broadgate Forum at Convene 155 Bishopsgate, Liverpool Street

Perhaps one of the most impressive aspects of the Broadgate Forum at Convene 155 Bishopsgate, Liverpool Street is the five-screen set-up in front of the window bay. The end-to-end ‘wall of screens’ creates a striking visual punch, delivering a sleek display of immersive content from the moment attendees arrive through the central doors at the rear. Better still, the landscape format of this conference room means that the audience is never far from the main stage and presenters.
A natural ‘crush lobby’ at the back of the room provides easy entry and ensures the audience can come and go without disrupting the speakers or those sitting in the back row. Another highlight of this room is the adjustable coloured lighting in the coffers that helps you fine-tune the mood to suit the tone of your event perfectly.
Getting your audience to the venue is easy since 155 Bishopsgate is situated adjacent to Liverpool Street Station which has great transport links.
