Hey Rowland, Below is a cutdown version of my DHCP. As you can see, I haven't really set anything up for ddns-update. While using Samba4's internal DNS I had the setting 'ddns-update-style interim;' and it seemed to have worked fine. But with bind I'm not sure what else is needed. Thanks for taking a look at it.
