In London there are plenty of both smaller more independent individual and small chains like Second Home [1] of co-working spaces as well as larger players like The Office Group [2].

I've not found the environment at most WeWorks to be anything special compared to most of these others, often not as good. WeWork's one big advantage is how uibiquitous they are in major cities, which is incredibly handy when travelling.
