In reply to wintertree:
Short-term it may save the NHS money, but medium term it is costing the NHSLA (litigation authority) a fortune.
Sorry if I'm repeating something, but due to the wording of most of the agreements, if a private contractor is negligent, the NHS foots the bill. A trainee paramedic just told me of a case where a private ambulance (+ "technician") was sent to a suspected cardiac arrest, chest pains, the works...
The technician says equivocally NO, you are not having a heart attack, going to hospital is a waste of your time and leaves. Of course, it was a heart attack, the patient died and now the NHS is footing the negligence bill.
This is not an isolated incident, private practices have no reason to improve as the NHS picks up the tab, every single time they make a mistake!
Edit, just reread the OP, going private as an individual is fine, it's the providers of privatised NHS contracts that are screwing the system...
