I'll pin my colours to the mast here. I had an independent midwife for the pregnancy, birth and post natal care of my second DC. It is the best health care I have ever received.
She explained at our very first meeting that she didn't have insurance for the birth itself. They can get insurance for ante and post natal birth.
She chose to practice without insurance because for some women NHS care is just not an option due to previous experiences. I think as women it is good to have choices. I was one of those women who had deep seated distrust of the NHS maternity system ( and I work for the NHS).
As it happened I was unable to have a home birth, but I always trusted the care and advice I was given by her.
For what it's worth I'm not well off. We saved like mad and I have taken shorter mat leave to be able to afford the £2500. It was worth every penny.
If they can't practice without affordable insurance then it removes choice of care from women. I think this is a very sad state of affairs.
Something else that hasn't been mentioned is that all independent midwives have a supervisor of midwives who generally works for an NHS trust. So any problems with their practice should really have been picked up via that route.
I think it needs to be acknowledged that even if they are insured, then insurers would only ever pay out if malpractice / negligence were proved. Insurance will certainly not cover all those unfortunate people whose DC are damaged due to birth.
Sorry have rambled a bit. I'd be very sad if women couldn't have the choices regarding midwife care that I'd had.
