Yes I feel for you. My advice is simple bin the whole thing, Sky are unscrupulus con merchants. Twenty or so years ago I had all sorts of problems with them.
Whatever it costs just get rid of them, if you don’t you will have ongoing problems and they will use every opportunity to increase your subscription.
If (when) they send out a technician (I won’t call him an ‘engineer’ as they are not) all he will do is swap a few boxes and go away, you’ll likely still have problems.
This looks even more like sabotage. Cutting the wires so close to the wall means it will be very difficult to strip back the wire shielding to be able to connect another piece to. That seems very deliberate sabotage unless more cable can be pulled out.
The engineer might need to go into your loft to put this right, in which case make sure there is nothing at all valuable up there before he turns up.
Realist, The wire l had plugged into the back of one of my other televisions, thinking it was the aerial, turned out to be the one that was cut on the outside!
I plugged in another cable into it and there was a signal on my television but it isn’t good like it used to be and just pixelates all the time.
The only things in my loft are, Christmas decorations and suitcases!
Sky have sent me a leaflet today for on offer on Sky Q multi- room!
Jazzi, That’s interesting and l wonder if this is something that happens regularly to people who change to Sky Q?
Please will you find out if it is a SkyQ in the new house, what her outcome was and let me know. Thanks.
Losos, Thank You for posting. I think your suggestion might be the best advice yet but l’m getting used to SkyQ now. It’s just having the signal troubles with my other televisions that is the problem still.
Thanks for updating us, Angel.
In your position, I’d definitely want to know why the Sky ‘engineer’ ‘tidied up’ the cables outside.
Hi Art, she is busy in her new job (transfer to another Sainsbury’s store) and she has said she will ring me when she has a day free for us to chat more. I’ll ask her about her tv then, but if she’s been worked since coming home from NYC then she won’t have had a chance to do anything yet.
Are you going to accept that your aerial leads could have been sabotaged, and just leave it? I wouldn’t. I’d get them down straight away to check, and rectify.
I second this. What they have done is dispicable
And I third it.
Angel, tell me the name of the idiot who destroyed your cables and Realist will come round and bash him.
If I’m coming round I’ll just fix all the cables myself !
Update… l am now in a predicament.
My friend who helps me came round the other day and he got all the other televisions working. He went into the loft to look at the booster box which is an SLX 8.
He said, it seemed to be working ok. He turned a knob on it and whether it did anything or not, the picture on the TVs does seem better. I still get pixelation at times.
He could not see where the ‘cut off’ cable goes to, or runs from.
My concern now, is Sky will come out, see the televisions are working ok and l have got used to SkyQ and the picture and could charge me for a wasted time and journey?
Well it’s pretty vital to your overall success that you determine what all the cables are TBH.
What needs to happen is for someone to put a current down the cable by say attaching a battery to it. There are essentially 2 wires to any aerial cable so an ordinary battery could be attached at both positive and negative ends.
Then go to all the aerial cables in each room and measure the current of each using either a simple meter or even a little light bulb.
You will thus find out exactly where that external aerial cable goes to and as a result will be able to correct everything.
Pixellated pictures are, presumably, not what you had before.
You still have cables that have been cut off (tidied up) and I’d be interested to know where they went to.
If they are NOT cables to the old Sky dish, then the Sky engineer who did it has some questions to answer.
EDIT:
Sorry Realist. Our posts crossed.
Art, I’ve been following this thread, even though it’s way over my head (no surprises there :-)) What a nightmare!
It’s probably nothing to do with your nightmare, but re your comment ‘pixellated at times’. Mine does that sometimes too, especially with low cloud around (but not always). I don’t have Sky or anything like that though, just Freesat (no aerial).
Pixelation arises from a poor signal from your ariel/dish, in the old days of analogue, a poor signal would result in a snowy or ghosting picture. With digital the last signal the receiver received stays frozen for a few seconds and then pixelates.
Signals can be affected by the weather, but it’s usually when the pressure is high, something to do with the ionosphere…
Bad connections or incorrectly aligned ariel’s are usually responsible.
I would recommend a new Ariel on the chimney and cable down to the splitter/amplifier Arty…
I reckon that a severed cable might be regarded as a bad connection! 
Come on, Angel. Get Sky to make the necessary repairs. You are in the right and they are in the wrong.
Call them out and tell them of your suspicions. If they deny responsibility, the next step would be to have a third party investigate the connections.
If, then, Sky are at fault they will be legally obliged to make good the damage they have caused. You have nothing to lose.
JBR and Realist, l did ring Sky (Sunday) to confirm that l would not be liable if the engineer felt that the visit was not justified.
The woman, l spoke to was great and said, l must tell the engineer what l am not happy with and they will do their best to rectify it.
If l am not happy after that, l can then go a step further and they will look into it.
That sounded fair enough to me, so the engineer’s visit on Wednesday will still go ahead.
I still have the wires that were removed even though, l had to retrieve them from the dustbin!
Pesta, 
Thank You for taking an interest in this thread.
l hope your brain hasn’t been addled with this ongoing saga!
Foxy, Do you mean an ordinary Digital/Freeview aerial? The one on the chimney now, is only 14 years old. I don’t think that is ‘old’ as far as aerials go?
I wonder even, if this is the mystery severed cable that is coming from my loft space through the outside wall? It may have been attached to the splitter/amplifier?
I think, what l really need is a hybrid LNB attached to the new SkyQ box.
Yes I tend to agree. They must have cut the feed from your signal booster in the loft which means the Freeview TVs aren’t getting a boosted signal.
You only need a Hybrid LMB if you still want/need FreeSat.
