It may seem bizarre, but it's not, it's telling you which transmitter gives you the most reliable signal for each multiplex, if you'd clicked on the Frequency Data link it would show you the predicted signal levels. (There is an error on this site for Crystal Palace as it lists C48 for PSB3 instead of C30, but many lists on this site haven't been correctly updated with all the 700MHz Clearance changes as the site owner hasn't had time.)
You'd get good reception from Hannington for all multiplexes, fractionally better for the PSBs from Crystal Palace, but poorer for the COMs except 7&8 which are marginally better from Crystal Palace.
The Digital UK Detailed Coverage Checker to which you refer was moved by Freeview/DUK from DUK's own website and amalgamated into the Freeview one (badly). There are boxes on the Freeview Homepage Freeview | All your favourite TV shows, all in one place and all for free & having entered your details, you then had to scroll down on the new page past all the Channels Icons to click Detailed view. After a lot of criticism they've since added boxes on the Corporate "Platform Management" page that take you straight to the Detailed view.
As you may recall the Detailed Coverage Checker gave a list of predicted transmitters and their multiplexes that may be receivable at the specified location, that's still the case. If you put your details in the boxes and check, you'll see that it's giving much the same results as you see from this site.
But bizarrely The Freeview/DUK checker suggests the most likely transmitter is Crystal Palace despite overall reception being somewhat better from Hannington! However this sort of oddity is also the case for a number of other locations and other transmitters.
HTH & explains what you're seeing.

It's certainly available on NowTV Entertainment packages atm.
If you have Sky, it seems to be available on Sky Go.
There's also some information on the following -

mc:
That rather depends on the type of comment you want to make. If it's about programmes and content, then it's the broadcasters themselves.
If you are having technical issues, you could ask here and maybe be pointed elsewhere if appropriate.

Alan Lloyd:
According to Freeview, Haslemere is currently listed for Planned Engineering with "Possible service interruptions".
This is the most likely reason for the issues you are seeing. They don't say how long the work is continuing but I wouldn't expect it to last that long.
Advise is not to retune in these circumstances.

charles: Please read the post immediately before your first one, it equally applies to you.
Rosalind Goodyear:
Do you mean "Freeview", you typed "freestat"? If so, then the post before charles is applicable.
Now 80s and Now 70s are not available on Freesat, there are on Sky.

I'm not sure what's given you the impression that there's engineering work going on at present. There's none listed for Plympton or Caradon Hill. The BBC aren't currently listing any faults, but if a new one has recently developed, there may be a reporting delay because of the current covid-19 situation.
There was some Tropospheric Ducting around several days ago which may have caused reception interference, but that cleared up a couple of days ago.
In the meantime, I would 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 the multiplexes shown in your TV's tuning section. Also check that your downlead looks undamaged (especially if it is old) and that your aerial seems intact and pointing in the correct direction.
Problematic connections, water ingress etc. can seem to affect reception of just an individual or several multiplexes.
If you've done those checks and the problem remains on Monday morning, I'd give BBC Engineering a call on 03700-100123.

You should have bought that particular variable attenuator that I mentioned at the time, it's now out of stock (I'll see if i can track down a similar one later). Yes, if the quality is dropping to 40% with the amp it could well be too much signal.
But what sort of figures were you getting for this 10dB attenuator between the aerial and amp?
If the aerial direct to a TV outlet was 100% signal and quality, it might be bordering on too much but if there's no breakup of picture or sound over a period, I wouldn't regard it as necessarily any problem. What I would try first is put the 10dB attenuator between the aerial and a single outlet (no amp) and see what figures you get. This will give you and idea of how much signal you've actually got.
Then try the 10dB attenuator between the amp and an outlet (but not the one with the PSU) and see what figures you get - again this will start to give you an idea of what is going on.
Attenuators are a very much under-rated diagnostic tool!

Brian Gregory:
You understand it wrong. The signal he's getting from the amplifier outputs appears to be far too strong. Until he discovers how much signal he's getting from the aerial as well as from an attenuated amplifier output, it's not possible to decide the best way to go. If for example he's getting enough signal direct from the aerial, I would be suggesting trying one of the 6-way splitters in the 2nd link you posted, which I'd already looked at yesterday.
You need to analyse the situation before rushing off to make suggestions.
(As an aside, have you bothered to read he reply to your own post?).

It just been announced (personally I'm disgusted and will be complaining to OFCOM and Arqiva) that COM8 is to close on June 22nd see 22 Jun 2020 - Important channel broadcast changes | Freeview
so we'll be loosing Channels 4+1 HD, 4seven HD, TJD HD and a number of +1 SD channels. Other COM8 channels will be moving multiplex (some to COM7? & room possibly on PSB3) as well as COMs 5 & 6.
Not sure how your COM7 signal compares to COM8 and whether that will have any effect on the way you deal with this.

StevensOnln1 has explained how to find the Somerset mux in case you have an older set or aren't doing a full scan. The Somerset mux has transmitters at Taunton, Mendip, Coker Hill, Egford Hill & Hutton so unless your radio is badly located eg. if there are thick walls in the line of sight to the transmitter, or next to large metal objects like fridges/freezers that may screen signals, you should be able to get it. The stations on the mux are BBC Somerset, Capital UK, Heart Somerset & Smooth Somerset all transmitting in Joint Stereo.
You will get some Welsh transmitters because the signals will easily travel across the Severn Estuary. You'll probably get the SE Wales mux on Block 12C: 227.360 MHz and maybe Swansea SW Wales Block 12A: 223.936 MHz.
You shouldn't have any problem with the National multiplexes - the BBC on Block 12B: 225.648 MHz whether it be from Taunton, Stockland Hill, Mendip or Wenvoe, etc; the Digital One (D1) mux on Block 11D: 222.064MHz; the Sound Digital (SDL) mux on Block 11A: 216.928 MHz
