No you dont need experience as you've done the 4 year course
But in answer to your question- I don't think anyone will offer thier portfolio for you to look at, it's a LOT of work and understandable that people don't really want to send out thier personal info on the net...
The only option I can think of is contact some of the recruitment companies that are desperate for UK physio's (there are a lot of them!) and see if they would be able to give you some advice on the registration and competancies process- they'll probably fall over themselves to get you over there! Good luck!
