Returning to UK from Canada

I am a UK trained Physio who has been working in Canada for the past 8 years. I am thinking of returning to the UK but am not sure where to start with gaining employment. I have previous experience in the NHS and would like to return to that if possible. What are other peoples experiences? I am no longer HCPC or CSP registered. Would I have to do this before even applying for jobs? How is the job situation there now? When I look online there appears to be a lot of jobs available but are the lots of applicants? What are my chances as an overseas applicant? Any advice welcome.
