Thanks for that information. The two main games stores in London, one of which is Leisure Games, don't have the books in stock and don't know when they will be available. It seems Esdevium, the main UK distributor, don't know either so that August 21st date seems inaccurate considering it's mid September.
Are the books sitting in customs somewhere? Does Chaosium have an actual UK release date in mind? Interested and enquiring minds are keen to know.
