David McKay: It's down to money and what level of coverage each broadcaster is prepared to pay for, there is no one deciding which channels each individual town/village should receive. Broadcasting to all 1,100+ transmitters costs more than broadcasting to the around 90 transmitters that get the main commercial multiplexes, whilst the extra HD multiplex which broadcasts from 25 main transmitters costs less still. Flim4 +1 was moved from the PSB3 multiplex (which is broadcast from every transmitter) to COM5 which reaches around 90% of UK households. TBN were prepared to pay the extra costs of being on every transmitter (reaching 98.5% of UK households) and took the vacated space on PSB3.

It's not so much which programmes are transmitted from a specific transmitter, it's a case of which programmes are carried by a particular multiplex. There are 3 PSB (Public Service Broadcast) multiplexes, 3 main COM (commercial) multiplexes, and now only one temporary HD COM(7) multiplex.
There are some Local multiplexes which broadcast to a number of large urban areas generally with high population density, they carry a local channel and a handful of other commercial ones.
For technical and financial reasons COM7 is only broadcast from 25 main transmitters in the UK.
The 3 PSB multiplexes are broadcast from every main and relay transmitter in the UK.
The 3 main COM multiplexes are broadcast from just over 80 main transmitters in the UK, plus a very small number of "relay" transmitters in major urban areas.
Local multiplexes have much smaller coverage than main multiplexes.
The Broadcasters on the PSB multiplexes are covered primarily by legislation.
There's PSB1/BBCA which carries all the main BBC TV and Radio stations, and Local BBC stations in the relevant areas
There's PSB2/D3&4 which carries the main ITV, Channel 4 and Five programmes and some of their +1s
There's PSB3 which is the BBCB HD multiplex (for which your receiver must have a T2/HD tuner) carrying the PSB broadcasters' HD channels plus a small commercial space for an extra SD channel or two.
It is highly unlikely that any individual will have any influence whatsoever over which commercial broadcasters are carried on which commercial multiplex (or part thereof). It is a commercial decision between the broadcaster and the multiplex operator. It also a commercial decision about whether there would be any COM multiplexes on any given relay transmitter. In most cases, relay transmitters do not cover a large enough population to make it commercially viable to pay for such equipment at a transmitter.
A while ago Channel 4 decided they no longer wanted to have Film4+1 on the PSB3 multiplex (a commercial decision), it moved to COM5/ARQA. Also TBN negotiated to move from a COM mux to PSB3. Recently Shopping Quarter has moved to PSB3 (LCN74 in the EPG).
Unfortunately, you live at a location that is only reliably served by a relay transmitter (Ripponden). Although there is some poor reception predicted from the main Emley Moor transmitter, it would likely be quite unreliable. If you want a greater choice of channels, you would probably be best going for Freesat if you have a clear line-of-site to 28deg.E A lot of modern TVs have a built-in satellite tuner so you'd only need a dish and LNB if that was the case.

We don't know which transmitter you are receiving from. Apart from Crystal Palace, there is a couple of "relay" transmitters that also broadcast the Local multiplex for London Live, eg. Reigate & Hemel Hempstead. None of these transmitters are listed for Planned Engineering, so it's more than likely that the bad weather has shifted your aerial or damaged it or the downlead. You are best having a look at it to see if it's still pointing the correct way (also compare to neighbours aerials) or whether the downlead is flapping around which could mean it's damaged etc.
If there are no visible signs of a problem, unfortunately you'll have to get someone with the correct knowledge in to check for you. Some professional installers may do that for a minimal charge unless you want/agree to them replacing/fixing the problem. If you go for an installer, try to get someone recommended or you know is ok. Lots of cowboys out there.

We have an indoor aerial, that up to recently had approximately 105 channels, but we
currently only have 49 channels on the following multiplexes pointing at rowridge
CH21 8
CH22 20
CH24 17
CH27 12
Can you advise whether there have been any issues or what I can do to improve our sigoal?

I can't find any listing of any recent/current faults at Rowridge and it's not currently listed for Planned Engineering.
Obvious things you can do is check your leads and connections. You should be getting multiplex signals on UHF channels C27 and C28 and maybe the temporary HD mux COM7 on UHF C55 and the Local mux on C37 but the latter in particular will depend upon location and we'd need a full postcode to see what your predicted reception is likely to be.
If your connections/leads are ok and the aerial is in precisely the same location as it was before. check that there hasn't been any other changes, new (metal) objects or other things nearby but especially in the "line-of-sight" to the transmitter, tree growth outside, new buildings or scaffolding being put up etc.
If there are "new" things possibly affecting reception, all you can do is try repositioning the aerial, having the rods vertical may improve reception of the 6 main multiplexes as they are also transmitted with vertical polarisation at Rowridge but you won't get COM7 or the Local mux as the are only horizontally polarised.
