Neil Robbins: COM8 is being closed because it is not commercially viable for Arqiva to operate it any more. It won't be replaced with anything else, as it was only ever a temporary service which was always going to close in the next couple of years (along with COM7) when the frequencies it broadcasts on start to be used my the mobile networks for 5G.

Neil Robbins:
There are no multiplexes closing in the Truro area, the Redruth transmitter group serving West Cornwall, or any in of the East Cornwall or most of West and South Devon, areas - Caradon Hill, Huntshaw Cross, Stockland Hill, Beacon Hill, & Plympton transmitter groups. The temporary multiplexes COMs 7&8 (that were HD but carried a number of SD channels as well) all closed in these areas with the 700MHz Clearance programme during 2019.
This was primarily for technical and financial reasons as the Multiplexes needed to move to UHF channels 55&56 and operate as SFNs.
UHF C55 & C56 are in what's called the Centre Gap" allocated for mobile SDL and usage of these frequencies is not expected to be required for some time. The multiplexes are transmitted from only 25 Main Transmitters serving around 70% of the country. Initially OFCOM wanted to close them by June this year but Arqiva wanted to push the date later and no definitive date was agreed. Many websites (and this one) never corrected the information saying they were closing in June 2020.
In March, OFCOM announced the details for the auction of the 700MHz band (and 3.4GHz etc) for 5G use, the date of the auction TBD. All this was dependant on the 700MHz clearance (except C55 & C56) being completed in May. Because of the Covid-19 situation, the remaining clearance programme was suspended in March. At this time it's suggested that it'll be early 2021 before it continues.
Recently, OFCOM got round to updating the Arqiva licence for these two multiplexes to bring it into line with the proposals they'd suggested for the auction. Whichever MNOs (if any) buy the centre frequencies in which these two muxes reside, then they may give 3 months notice for closure, or there's an end-stop date of 30th June 2022 whichever is sooner.
See https://www.ofcom.org.uk/….pdf
As it so happens, leading up to this, Arqiva made a commercial decision to close COM8.
Quote -
"The initial licence period comes to an end in June and Ofcom has issued revised licence terms reflecting the fact that the services may have to terminate at short notice if the spectrum is needed for mobile data services. Given this uncertainty, and through discussions with the channels on Com 7 & 8, Arqiva has taken the decision to rationalise the services onto one multiplex.
The Covid-19 crisis has caused some uncertainty over the precise duration of the licence for some of the channels using Com 7 & 8. This has meant that there was not enough demand to make it financially viable to maintain two multiplexes.While channels are closing and we do appreciate that this may cause concern, a lot of work has taken place to ensure that viewers will still have access to the same content via main channels and on demand services."
See 22 Jun 2020 - Important channel broadcast changes | Freeview
(COM8 will be off-air by the end of the month).
In practical terms, the earliest COM7 would be likely to close would most likely well into 2021 or later. The 700MHz frequency clearance has to be completed (postponed because of Covid-19), currently suggested to be early 2021 and the auction has to be held. Encoders to use SDL on the centre frequencies need to be developed (and installed) as well as handsets. It's not going to happen in a hurry.
The nearest transmitters to you that transmit COM7 are Wenvoe, Mendip & Rowridge.
HTH.
