All uni's over here expect considerable work experience before applying, usually a couple of weeks (minimum) in hospitals where you can see all the different aspects of physio, not just in private clinics.
Most hospitals are happy to offer WE, if you call them up and ask to speak to the physio managers they can usually arrange for you to come in and shadow the physio's. I suggest anyone does this before applying, a lot of people like the idea of physio when all they've seen is sports or private clinics, then when it comes to dealing with elderly, stroke patients, mental problems, intensive care etc people go off the idea...
I did varied WE including hospitals, community clinics, private clinics, rehab hospitals as well as private kids hospital etc... the more variety the better but you MUST get some acute experience (hospitals) otherwise you'll probably be rejected as generally uni's want you to work in the NHS ultimatley- if you tell them you want to do sport it's a real turn off for the uni's!
A few people on here have actually worked as physio assistants/technical instructors before applying (which is becoming the requirement these days as the course is so popular!), which is the best way of getting work experience as you get to understand how a physio department works as well as huge amounts of work experience. The vacancies are few and far between but if you look on the NHS careers website they post vacancies or you can contact your local hospitals...
