Thank you Lady Rainicorn that's really helpful. I was thinking about calling BUPA anyway to see about transferring. We have exoenses coming up in November which Medibank would have covered. We have needed the insurance so little over the past decade it aggrieves me that when I finally need it we won't have it! We can't delay the move and I know the NHS is and can be fabulous. I just want to explore all options.
I will also talk to Medibank about putting our cover on hold. We've done it before when we were O/S with hubby's job and it was pretty straightforward. Thanks all. I'll report back if I find out any other info.
