Can I get a faculty job in the UK without UK experience?
I am not sure what type of answer you are looking for. Based on personal experience as an American with all my education and training in the US, my first faculty position was as a lecturer in the UK. There are no laws requiring UK experience to get a faculty position of any rank in the UK. There are laws that give preference to those who have a right to work in the UK, but that is not the same as UK based teaching/education experience.

While some schools may prefer individuals with UK based experience, it was never something that came up during our searches. That said a familiarity with the UK system is helpful for demonstrating you can be a good tutor and help advise students.
