SnugglySnerd That's good to know, thanks. I hadn't thought of the training side of things. I suppose you're right. 
The main difference from my point of view is the length of the appointment. 5 or 10 minutes is common in the NHS, whereas in private care I can choose the length of the appointment as long as I'm prepared to pay the fee. In private medicine I often get seen much sooner and can choose a date. I can also go back to ask further questions if they come to me, which isn't always possible with NHS consultants.
Having said that, I find that NHS people are often very committed and competent, whereas sometimes private people are kind of less interested.
Need I think you're totally right. I need to get my network sorted out so I can find the good people. I'm getting good at this with tradesmen, but not so much with medical people.
One of the advantages of having moved to a GP surgery that is closer by is that suddenly all the people at Church are fascinated to know how we're getting on, so I think I will start asking more questions of them. I'm sure they must know things that I don't.
Good to have your confirmation that that is what's going on though. Glad your skirt is nice.
btw the dietician told me that ds and I need chocolate and ice cream, and not just some, but lots. Rock on!
