I am with the Oakwood midwives who are a caseload midwifery group and my midwife told me the other day that they are willing to take women who are not from their GP surgery (forest hill group practice). She said you can refer yourself by calling them and if they have a space they will take you and if not, they will put you on a waiting list and then call you if someone moves away. I see the same 3 midwives for all apointments at home and they will be there for my birth as well. I've found the care fantastic so far, so give them a call!
