Just wondering whether there is a possibility that Seagry Court will ever get the COM channels added?

Will:
This page is a bit confusing as it hasn't been fully updated. The UHF channels are listed in the table lower down, but the COM muxes aren't mentioned in the top section and the power was increased to 200W for each mux.
For clarity the UHF channels are C39, C42, C45, C40, C43, C46 in the order PSBs1-3, COMs4-6.
If you are receiving the PSBs you should get the COMs. Aerial polarisation (rods) is Vertical for Seagry Court.
Provide a full postcode if you are having problems and we can look at your predicted reception.

Hi,
There is an error on this page (Seagry Court). Whilst the transmitter information now shows all 6 MUXes, the channel list shows the pre-upgrade position when the transmitter was Freeview lite.

The "transmission frequencies change over time?" section below that is actually correct, which is at least something!
