I would largely echo your sentiment Peter. There's a general consensus that it is much more difficult to raise equity funding (and to a lesser extent debt funding) in the UK than in the US within the search space. Those in the UK that are successful in raising equity tend to overwhelmingly be from 'Old Money' networks, which isn't the case in the US.

If you have the opportunity to search in the US you should certainly explore it as an option

Thanks Darnell, I've funds to apply for an investor visa in the USA but my wife who is a doctor is reluctant as the exams to transfer her qualifications are tough. Let's see what happens, the UK with the new socialist government is becoming more adverse for businesses.
