"We" don't keep doing anything, this is an independent technical helpsite for people for technical and reception problems. What I can tell you is that Emley Moor is currently listed for Planned Engineering with "Pixelation or flickering on some or all channels".
However considering you general location, the predicted reception is excellent for all multiplexes and I'm a little surprised that you are seeing a problem like this unless perhaps your reception is marginal for some reason.
If you are correctly tuned, other than that, check that your aerial seems intact and pointing in the correct direction bearing 188 degrees (8 degrees W of due S) with the rods (or squashed Xs) horizontal and that your downlead looks undamaged and isn't flapping in the wind.
GB News is carried on the ArqB multiplex, so you may be noticing the issues with other channels on ArqB.
See Channel listings for Industry Professionals | Freeview for which channels are carried on which multiplexes.
Are you seeing problems with channels not on ArqB, if so which ones?
Check in your TV tuning section that you are tuned to Emley's UHF channels -
Emley's Multiplexes & UHF channels are as follows, in the order -
PSBs1/BBCA, PSB2/D3&4, PSB3/BBCB HD, COM4/SDN, COM5/ArqA, COM6/ArqB, COM7 HD, & Local
C47, C44, C41, C33, C36, C48, C55, & C39/C42. Whether you get satisfactory reception of COM7 will depend on your aerial installation.
Also check all you coax plugs, connections, flyleads etc, unplug connectors check for corrosion or other problems and reconnect them. Flyleads can be a common problem, try swapping them.
See what Signal Strengths and Quality (or Error/BER) figures you are getting for the multiplexes (groups of channels) shown in your TV's tuning section, this might indicate potential issues with your aerial or downlead.
If you post the figures for each it may give us a clue.
Roughly how old is the aerial installation? There might be some degradation somewhere.
Do you have a distribution amp/splitter and where is it located? If you have one, check that it still has power and check the connections to it.
Aerial misalignments, problematic connections, water ingress etc. can seem to affect reception of just AN individual or several multiplexes.

Betty Harkness :
Which channel are you getting that on, BBC One Scotland SD or HD, or BBC News?

No faults are being reported at Wenvoe that I can find and it's not currently listed for Planned Engineering.
Sky Arts (LCN11) is carried on the ArqA multiplex.
See Channel listings for Industry Professionals | Freeview for which channels are carried on which multiplex (groups of channels).
Are you missing any other ArqA channels at all?
It would be worth checking in your TV tuning section that you are correctly tuned to Wenvoe's UHF channels.
When Freeview juggled a lot of channels LCNs towards the end of January and you probably retuned, Wenvoe was listed for Planned Engineering and there may have been weak signals at the time you retuned and some multiplexes may have inadvertently tuned to another transmitter - there are several you could pick up at your locale.
The UHF channels for Wenvoe are C41, C44, C47, C42, C45, C39, C55, C37 that's in the multiplex order BBCA/PSB1, D3&4/PSB2, BBCB HD/PSB3, SDN/COM4, ArqA/COM5, ArqB/COM6, COM7, Local.
(C means UHF channel).
If you are correctly tuned and still have a problem, I would check that your aerial seems intact and pointing in the correct direction (bearing 227 degrees, pretty much SW for your locale) with the rods (or squashed Xs) horizontal, and that your downlead looks undamaged (especially if it is old) and is secure and not flapping in the wind.
Also check all your coax plugs, connections, flyleads etc, unplug connectors check for corrosion or other problems and reconnect them. Flyleads are a common problem, try swapping/changing them. See what Signal Strengths and Quality (or Error/BER) figures you are getting for the multiplexes (groups of channels) shown in your TV's tuning section, that information may indicate issues with your aerial or downlead or possibly any distribution amp/splitter you may have.
Problematic connections, water ingress etc. can seem to affect reception of just an individual or several multiplexes.

You may already have noticed that posts can take an inordinate amount of time to appear on this site.Please wait several minutes before reposting to see if your post appears.
I do wonder who your friends have been using to replace aerials, because it sounds to me that they should have been advising about the free availability of filters, it rather sounds like they could be on a bit of a money maker!
I would get them all to complain to restoretv.uk and ask why you haven't been warned about the possibility and why you haven't been sent information.

Desmond Robbins:
If you are watching on Freeview, which transmitter do you receive? Those channels you have mentioned are on different multiplexes (groups of channels).
See Channel listings for Industry Professionals | Freeview for which channels are carried on which multiplex.

doorsy gall:
None of the transmitters that you might receive in your general area are currently showing any reported faults.
Have you checked that your aerial looks intact and is pointing in the correct direction (compare to neighbours if need be). Also check that your downlead looks secure and isn't flapping in the wind.
Check the connections behind your TV and that everything is plugged in correctly.
Are your neighbours having the same problem? Which way do their aerials point?

From the outset, COM7 (as was 8) was a temporary HD multiplex only ever initially transmitted from 30 main transmitters. This reduced to 25 with the 700MHz Clearance program as it wasn't cost effective to modify antenna and transmitters at the 5 where it closed.
COM7 is currently scheduled to close by the end of June 2022 under its current licence. No announcements have been made about what will happen to channels currently carried on COM7.

Vin:
Your most likely transmitter is Crystal Palace assuming your aerial is pointing at bearing 31 degrees, that's ~9 degrees E of NNE. If it's pointing at Reigate, bearing 195 degrees (almost SSW) with its rods vertical, you only be predicted to get reliable reception of the 3 PSB multiplexes (BBCA, D3&4, BBCB HD).
See Channel listings for Industry Professionals | Freeview for which channels are carried on which multiplex.
Neither transmitter appears to have any faults recently reported, however Crystal Palace is currently listed for Planned Engineering with "Screen may go black on some or all channels".

Posts sometimes take an inordinate amount of time to appear on this site, so please wait several minutes before reposting. Also, there is little point in subsequently repeating your post at 1/2hrly intervals, it won't get a quicker response.
I think you are not looking at your TV tuning section correctly as there have been no Freeview transmissions (on any transmitter) on UHF channels C56 & C57 since the completion of the 700MHz Clearance program in August 2020.
The list at the top of this page has not been fully updated since the end of the 700MHz Clearance as the site owner has not been able to find time to update everything.
See my post (p219, Saturday, 5 February 2022, 8.08am), the one just before your first post, for full details of Winter Hill's UHF channels.
I can't find any reports of any faults at Winter Hill (the BBC are normally very good at providing information as COM7 problems would affect BBC News HD and BBC Four HD), and the transmitter isn't currently listed for Planned Engineering.
As you haven't provided a full postcode the information may not be 100% accurate.
If there are/were to be any new 4G/5G transmissions in the 700MHz band near you that would affect your reception, then you should have received a postcard from https://restoretv.uk/
The mast would need to be very very close to you if it were not on the line-of-sight to Winter Hill, even then it would need to be within 1km or so.
If there is such a mast, then a Free filter would be obtainable from restoretv.uk Such a filter would cut down all transmissions above UHF C48. In any event COM7 is a temporary mux due to be switched off by the end of June2022 under the terms of its current licence. If you are getting 4G/5G interference a filter is still recommended contact restoretv.uk for more information and detail about nearby masts.
All that said, there is one more common source of problems with interference to C55. Have you altered anything around, moved cables etc. in your installation? Make sure you don't have any HDMI cables near any unscreened/poorly screened flyleads/aerial leads especially if those aerial/flyleads aren't double screened coax as HDMI has been known to cause interference.
