Neither Freeview nor the BBC are currently reporting any faults at Ridge Hill and it's not currently listed for Planned Engineering. You might be in a location where reception especially of the SDN/COM4 multiplex is a bit marginal but without a full postcode we can't see what your predicted reception might be.
Whilst there is some variable intermittent "Troposheric Ducting" around at present that's been quite strong in some parts of the country causing interference from distant transmitters (see
https://www.bbc.co.uk/rec….jpg ),
if your issue has been continuous for several weeks there could be some additional reception problem with your installation.
I would check that your aerial seems intact and pointing in the correct direction and that your downlead looks undamaged (especially if it is old). 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 you are getting for all the multiplexes shown in your TV's tuning section, it may indicate some issue.
Problematic connections, water ingress etc. can seem to affect reception of just an individual or several multiplexes.

Transmitters normally go off just after midnight. The retune is normally complete on main transmitters like Winter Hill by 6.00am, but as this was originally scheduled for April, and they've been have a practise with a few things during planned engineering in recent weeks, you never know, it may be back on sooner. But then again, unexpected events can occur!!
If it's a relay transmitter, they usually happen a bit later in the morning and some have to wait until the afternoon.

Mellow Magic is one of the many Bauer owned radio stations that no longer broadcasts in analogue, either on MW or FM except it's sister station "Magic FM" on105.4MHz in the London area, also on Freeview 715.
Mellow Magic is available on DAB, on the SDL multiplex, Block 11A 216.928 MHz. Nearest transmitters are Hemel hempstead, or Zouches Farm (roughly west of Luton).
Btw, all these stations are available to stream on-line.
If you don't have a DAB radio and ever go to buy one, make sure it has DAB+ (DAB plus) as more stations are now moving to this mode of transmission. There are still far too many DAB only radios on sale especially in large "superstores".

15 miles? More like 5, km even? That aside, you shouldn't have lost any channels, the signal from the Rowridge transmitter should be blowing your windows out!
The channels you've mentioned are all on different multiplexes (groups of channels). Are any other channels missing?
That said, when did you first try to check the channels? Did you retune and when?
What do you know about the aerial installation where you've moved?
I think the first thing I would try is unplug the aerial and carry out an automatic retune. This should clear memory of all previous tuning as nothing should be found.
Plug the aerial back in and repeat the retune, hopefully all channels should be correctly restored. If not you need to carry out some checks.
The aerial should be pointing roughly SW with the rods horizontal.

All the above said, there is also some strong variable intermittent "Troposheric Ducting" around at present that's been quite strong in some parts of the country causing interference from distant transmitters (see
https://www.bbc.co.uk/rec….jpg ). This won't necessarily affect all multiplexes or affect any one or several at the same time. This might mean that retuning may not get all the channels or even get the wrong transmitters and you'd have to retry several times once conditions stabilise.

A further thought on this, you might have got accidentally tuned to the Ventnor Transmitter (roughly due S of you) whereas Rowridge is roughly SW, both could be within the beamwidth of your aerial.
When you've first done that retune that I suggested, check in your TV's tuning section that you are tuned to the following UHF channels for Rowridge -
C24, C27, C21, C25, C22, C28 & C55 also C37 but not Ventnor on C33, C34, & C36.
That's in the order PSBs 1-3, COMs 4-7, Local mux. PSBs only from Ventnor.
For which channels are on which multiplex, see Channel listings | Freeview (that's when it's working, it's down at this time of posting).

If you are referring to a post you made on this public website on Friday, 30 March 2018, you put the information in the post and made it yourself, no-one else disclosed it but you!
If you want the post removed, you will need to contact the website owners, making another post here will have no effect. This is an independent technical helpsite for people that want help with reception or other tv/radio technical issues, and most contributors that respond have nothing to do with this site.
This page is about how to contact various broadcasters or others in the industry to make a complaint, not this website.

If you didn't have any problems receiving COM7 before June 22nd, you really shouldn't have any problems now as there've been no changes to the transmitted power of COM7 (C55).
Do you know exactly what aerial you have? What sort of strength figure are you seeing for C55?
To look at the predicted reception at your location, we need a full postcode. You might unluckily be in one of those spots where reception of C55 is not as good.
But also, make sure you don't have any HDMI leads (if you have a PVR or other devices) that are close to aerial cables or flyleads, as HDMI leads can interfere with C55 if the aerial cables are not good quality and double screened.
Other than that, check that your downlead looks undamaged and that your aerial seems intact and pointing in the correct direction. 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. Problematic connections, water ingress etc. can seem to affect reception of just an individual or several multiplexes.

I'm afraid you are wrong old chap. It is still on 46.
You are most likely picking up PSB2 from the Fishguard relay which is not too surprising considering your location. If your aerial is still pointing at Trefin you should be getting it on C22. If you've recently retuned, changes in reception might be due to strong Tropospheric Ducting which has intermittently been affecting different parts of the UK in recent days.

IF they can see the mast and the indoor aerial does not have to point through any thick walls, then there is a chance IF they are not too far from it, it's a very very low power relay, but as StevensOnln1 says, we really need that full postcode.

You shouldn't have any reception problems with any of the main multiplexes or the local Liverpool multiplex from the Winter Hill main transmitter at your location, it should be very good.
QVC on 111 is QVC HD and it's SD channel is the one on LCN16. These are on different multiplexes.
For which channels are on which multiplex see Channel listings | Freeview
Are you missing any other channels?
It sounds as though your set's memory might need clearing, so do so as follows -
Unplug the aerial and carry out an automatic retune, this should clear all previous tuning as nothing should be found. Switch the TV off for at least 10 minutes.
Plug the aerial back in and switch on, and carry out an automatic retune. Hopefully all the channels will be correctly restored.
