Physio(therapy) - that's what they call it here in the UK - is available on the NHS or privately. As you'll be resident here in the UK for your job, I don't see why you wouldn't qualify for free physio on the NHS. My wife is a physio at a hospital just outside London, I'm sure she could supply me with better details.
You should be able to go on an outpatient basis but I don't know what, if any, waiting list there might be. I imagine private could be rather expensive but maybe your employer would pick up the tab?
