Just to pick up on what summerinthesunshne said earlier.
Private care can give you better access to one-to-one care from a midwife (particularly postnatally) - absolutely. I wouldn't dispute that. Also, you will get to see a named consultant as standard (which you would only get on the NHS if you had a risk/need for Consultant-led care).
I think the point I wanted to make was that, when push comes to shove, if anything goes seriously wrong, there is absolutely no improvement in outcome in private hospitals / wards. I think it is really important to be clear about that before you spend large sums of money.
Very few private hospitals can offer the level of care (by which I mean medical care, not support) to high risk patients that a large NHS teaching hospital like, say, UCLH, can.
I am not anti private care, btw. I just think it is really important to weigh up what it is you are expecting from private cfare against the cost. If you want the very best medical care - a sort of 'extra protection' - if things go very wrong, private care isn't the best solution in my opinion. However, if you want a better level of 'customer service' throughout your pregnancy and birth, then undeniably, if you pay for it, you get a much better level of customer care.
