One must not wait until the top or bottom of the hour after the start of broadcast. The broadcast is BBC Three, which in effect means BBC iPlayer. The episodes are thus "broadcast" at 10AM, and pages for the episodes may be created on or after 10:30, British time. No, we do not have to wait until it's been broadcast on BBC One.

This is not at all the first show to start on BBC Three. Torchwood series 1 was broadcast on BBC Three only (in the UK).
