There’s clearly room on TSID 101 for more channels - it only has 5 SD channels on it. You are ignoring that HD and SD channels could sit alongside each other (ITV PPV HD for example). This stream is also used for Sky Box Office HD events.

I’m not being antagonistic, I’m just pointing out that much of the analysis thus far is unhelpful. You keep stating opinions as absolute facts.

There’s room for one HD channel on a single frequency you identified.

Not considered:
Unused frequencies
Moving remaining 64 QAM multiplexes to 256 QAM
More efficient use of the space that is in use
Lowering the bitrate of some channels.
