In reply to BradleyWhite:
as high climber said. Personally Ive had no problem getting log book days with all sorts of groups at all sorts of centres (private and local authority) all done through "their" insurance as being non qual you would be an extra body anyway. Once you have your tickets and are "leading" sessions then worry about insurance.
Contact as many providers as you can and get yourself out there. My log book voluntary work has in most cases led to some paid work once I got the ticket. I still do a bit of voluntary with one of the charities I found as I enjoy the sessions and client group. Dont forget to get a job lot of personal days out with your mates too! Its all experience. Good luck.
