Here's a Freedom of Information response that suggests BBC News HD is always (at least) 10 seconds late on a story.
Distribution delays are essentially fixed for a
given platform and are a result of the time it takes to assemble all programmes (whether live or
recorded) and turn them into a form suitable for transmission. This process takes around 4s for
standard definition TV and 6s for high definition TV.
In addition, we add a fixed delay to some services on satellite to allow all our channels to
efficiently share capacity. [The capacity required by a given service varies with time so capacity is
dynamically shared between all channels; simulcasting programming on more than one channel,
such as with multiple variants of BBC One or the news on BBC One and BBC News Channel,
hinders this dynamic allocation process. Delaying certain services by a few seconds can allow the
dynamic allocation to work more efficiently.] Currently BBC One Wales HD and BBC One
Northern Ireland HD are both delayed by 2s each while BBC News HD is delayed by 4s.
