C1000 pax party venues in London

We’re on the hunt for some venues in London around the 1000 person capacity that would be up for hire on Saturday nights. We’re at the point where the smaller venues are too small and the bigger ones are too big. Any recommendations would be welcomed. A lot of the better-sized venues in this category are running weekly events and not available to promoters.

One venue we use is Electric Brixton, which is excellent and scalable, but is mega busy and securing dates there is getting more and more challenging as London is feeling the pinch of a medium sized club (for hire) shortage.

Have you checked out Great Suffolk Street Warehouse?
