As I said, there has been no change in power transmitted, COM7 has been at 22.9kW for well over a year according to DUK (probably at least since it moved to C55 in Mar.2018 without looking up some old documents!). The listings on this site are out of date as the site owner has not had time to update them - in fact there are currently a large number or errors on this site that currently need fixing.
As you haven't given a full postcode, I don't know your predicted reception of the various multiplexes, so there are a number of points to make so as not to create misunderstanding for other posters or readers -
1) You won't have problems with 5G transmissions as they won't be transmitted at anything like the same sort of powers and they will be transmitted from MNO local masts, so unless you will have one very close to you especially on the line-of-sight between you and Winter Hill, you are very unlikely to have a problem.
2) 700MHz frequencies haven't even been auctioned yet and it wil be sometime later next year at the earliest before any transmissions are likely to start anywhere in the country after the sale - tx equipment, antennae & etc have to be set up, handsets have to be available on the market and so on!
3) For the tiny minority that might be affected, 700 MHz filters will become available.
4) Assuming you are in an area predicted to receive all multiplexes, if you want to receive all current multiplexes from Winter Hill (& the other 24 main transmitters that carry COM7) you ideally need a Group T aerial which doesn't include the 700MHz band. (A Wideband will also receive the multiplexes for anyone that has one, and there would be no need to change it. )
5) If you are in an area that can get the Preston Local multiplex but not COM7 (or you are not interested in COM7) then a Group K aerial should be used as a Group A may not have adequate gain at C40. In fact there are SOME Group K aerials being sold by one supplier I know of (ATV) that they have tested and would usually have sufficient gain for C55!
6) Even in weaker signal areas those same Group K aerials may have better gain in Group A channels than the average Group A aerial unless you are starting to look as some very high gain spec. aerials.
7) In strong enough signal areas, a lot of people will get adequate and stable reception of all the new channels on their old aerials.
8) For those not getting stable reception of the PSB multiplexes especially (BBC, ITV, Ch4 & Ch5 etc.) then if they don't have cable or satellite, are in their own home with their own aerial, they can get a free replacement from Freeview by contacting them as detailed in my previous posts.
I hope that is now nice and clear for you. And for anyone else reading, I've given a lot of updated information and advice in many previous posts here over recent weeks, it could be useful to read some of them.

If you read the previous posts, it's a problem with signal strength not where the channels LCNs are in the EPG.

You should get excellent reception of all main multiplexes and the two Local Manchester ones from Winter Hill.
There's no reported transmitter problems at Winter Hill or a couple of nearer relay transmitters although one of them is lised for Planned Engineering.
It possible when you retuned, you might just have done so at a time when reception of some mutiplexes from Winter Hill reception were affected by interference or engineering and inadvertently got tuned to one of these weaker realy stations.
You could first try a retune BUT done as follows - unplug the aerial and carry out an automatic retune. No channels should be found so this should clear memory of any previous tuning.
Plug the aerial back in and carry out a manual tune if possible, UHF channels are -
The main multiplexes are C32, C34, C35, C29, C31, C37, C55 for PSBs1-3, COMs 4-7.
The Local ones are Local Manchester, Manchester GI on C24 & C27.
If you are unable to do manual tuning then repeat the automatic one and check it tuned to the correct UHF channels in your TV Tuning section.
Now there is another possibility if this is not a very recent problem, but has been occuring continuously since August the 12th. Before that date, were you getting the main BBC channels at LCNs 751, 752 etc. in your EPG rather than the usual 1, 2, 9 etc.? And since that date have you've lost those and had intermittent problems with some of the others as well as the ones you've just mentioned? If so, then it may be that your aerial could be an old Group C/D and is not able to reliably receive the multiplexes on the new UHF channels. If you know you have a Wideband aerial, then there could be other issues.
Check that your aerial looks intact and is pointing in the correct direction ~WNW bearing 298 degrees at your location with the rods horizontal Check all your coax plugs and connections for any bad connections or corrosion. Check your downlead looks intact and undamaged and is secure.
If it turns out it's an old aerial and you had to watch BBC channels at 751, 752 etc. and it's your own home and aerial, and you don't have satellite or cable, then you can get free help from Freeview with a replacement aerial FoC. Ring them on 0808-100-0288.

Hi, we had real problems with reception yesterday which I assumed was the atrocious weather. However, it led me to check signal strength on the tv which showed very low values for strength and quality. Today I've checked again (clear skies, no rain) and still find what I would think are low values. The aerial/cabling is new, pointing to Winter Hill from Glossop (we're reasonably elevated) with no splitters/joins from the aerial right through to the tv. I've tried your recommended re-tune method but wondered if you could look at the values my TV displays (these are for BBC1 HD) and comment as to whether they are within an acceptable / expected range?
Freq.-586000KHz Bandwidth-8MHz Service ID-4484 Multiplex 10720(TSID 4088, ONID 233a) Network-North West(ID302a) Bit error level(E-6) 0 BER Signal Strength 14% Signal Quality 100% Channel ID 35
sorry If this is a bit over-kill but most of it is meaningless to me! Thanks for any help.

The information that's most important is the "Bit Error Level" (BER) being 0 (no errors), Signal Quality 100% - the signal is being received and decoded without any resulting errors. A signal level of 14% does seem rather low, but without a full postcode we can't examine the predicted reception for your location. You could well be in an "awkward" spot and that may be the best that can be expected but a lot depends on the aerial.
Who installed the aerial? What type, make, model is the aerial? How long ago was it installed? Is it low loss double screened coax that is being used?

Chris.SE:
Thanks for that Chris, and apologies for not providing the postcode (must learn to read before posting!) SK13 8ED. The cable is marked Triax RG6/U 19.5dB/100m (plus various other numbers) and is about a 25m run. Looking at Brian's aerial guide it looks somewhere between the class 2 and class 3 high gain types - there's 8 single horizontal elements (similar to the class 3) with the reflector having 4 horizontal bars per part as in the class 2, model unknown I'm afraid. It was professionally installed around 5 months ago and from the untrained eye seems to be solidly mounted. Checking this morning the figures for BBC1 HD are BER 500, Strength 9%, Quality 71% while such as BBC1 (non HD) show BER of 0, Strength 54%, Quality 100%

Hmm. Whilst you are actually predicted to get good reception from Winter Hill for all multiplexes except COM7 which could be quite variable, sometimes poor, you are nevertheless 42km from the transmitter. Are you getting a Local Station (Manchester) at LCN7 in your EPG?
Those latest figures for the HD multiplex are poor. What sort of figures are you getting for the SDN/COM4 multiplex on UHF C29, ArqB/COM6 on C37, and the Local mux on C24?
For which channels are on which multiplex see Channel listings | Freeview
Whilst TV set strength figures aren't definitive, they are a (good) guide and my suspicion is that the aerial I'm afraid sounds very much like a Class 3 and IMHO is not high enough gain considering your distance from the transmitter. The coax I wouldn't have not considered to be low enough loss for a 25m run.
I'm thinking that as it's all only 5 months old, getting the installer back mightbe a consideration, but lets see what the other figures are.

Hi Chris, thanks for the help. Yes, LCN7 in the EPG carries a local (Manchester) station. The other figures you requested are; SDN/COM4 - Strength=22%, Quality=100%, BER=0. ArqB/COM6 - Strength=8%, Quality=95-100%, BER=0 and Local mux - Strength=46%, Quality=100%, BER=0. I also re-checked BBC HD; Strength=8%, Quality=25%, BER=1400. These were all noted with this afternoons overcast/rainy skies. I did notice at the time that our aerial looked generally smaller than various neighbours who also point to Winter Hill, but the installer came highly recommended and I wasn't about to question his choice (doh!) Thanks again.

Sorry for the typo double negatives about the coax, to be clear IMHO it's not low enough loss, in other words it's not good enough quality for a 25m run (but it's not the worst quality) that coupled with the fact that it's not a high enough gain aerial results in poor signal at the receiver. (Best quality cable would be CT100/WD100 specification).
I should have asked if you were getting a signal for COM7 on C55 and if so what the figures are, I suppose that because the initial concerns with most people on Winter Hill is whether they have old group C/D aerials (doesn't appear you have) but also your prediction for COM7 isn't brilliant. Nevertheless it'd be good to see the figures.
With those figures I can suggest full "informed" comments you can give to the installer - any difficulty with him, you could also talk to your local Trading Standards people.
You can get away with lower quality cable if you have a high enough gain aerial, but the net result of the two should be a signal of minimum strength 45 to 60dBuV at the receiver as measured with a professional signal strength meter - the actual value the installer should be able to physically show you - not just state you've got it.
Higher values can always be attenuated if the need arises.
The only other point I should make is check you coax connectors and cable at the back of the TV to be sure you don't have any broken connections.
