I had alot of therapy on the NHS and have had a mixture of both good and bad. My latest therapy was for 2 and a half hours a week but there was very limited contact between the sessions. It was ok and T was the best of them all................unfortunately when she left she handed us over to someone who hadn't got a clue about what was needed and therapy become very painful. I stopped going and since then have had great problems trying to find a T to offer what we need.
Speak with your pdoc and see if he knows any answers to your questions and if he does you a referral make sure you have a list of questions that you can ask before you embark on it. In my experience there is not much contact or email etc between sessions.
Good luck in your search
