Excessive TV wiring - can I cut it away?

[panamacanal]

The previous owners of the house we've just moved into liked TV in every bedroom, so it has a lot of ugly wires on the outside. We only want TVs downstairs - one in the lounge at the front and another in the kitchen at the back - so we'd like to get rid of some of the surplus wiring if possible.

The first and second picture show a wire that goes from my son's bedroom up toward the roof. Am I right in thinking this is a traditional analogue TV aerial? Can we just cut it away or is that a bad idea?

The third photo shows a Virgin Media box - does anyone know if it has a special name? There is 1 of these in the lounge, 1 in the kitchen and 1 in the loft bedroom. We do have a Virgin Media subscription so the engineer connected us to the box in the lounge when we moved in. Can we plug in our kitchen TV into the second box and get the same service or will that involve an additional subscription? Also, can we cut away the ugly exterior wiring for the upstairs box (see fourth photo which I'll post in the next message), or are all three likely to be inter-dependent?

There is additional wiring for BT Open Reach, which goes into the lounge at the front, but also travels up the outside wall, to an outlet in my son's bedroom. Can I cut this wire away (see fifth photo which I'll post in the next message)?

Finally, there is a Sky satellite dish at the back of the house (on roof of the single-storey rear extension, with a wire that goes all the way around to the front of the house and pops through a hole in the wall of my lounge. It's not connected to anything. Can I cut it away?

There shouldn't be any issues with cutting away the TV wiring, although obviously it will be neater if you disconnect it at the far end and remove it rather than leaving cut ends hanging.

I don't know about the Virgin boxes, but I'd be tempted to leave them if you have virgin service. You can probably plug into any of them, but you might need a special subscription if you want to have multiple TVs attached.

For the openreach wiring, you can't cut the dropwire from the pole to the NTE (master socket), but anything coming back out of the master socket is yours to remove. Again, best to remove rather than just cut.

sky dish - yep, just remove it.

You can use the Sky dish for Freesat. Just an option.

Have you got a loft? My house was exactly the same (cable in every room!) but we found the splitter in the loft, disconnected from there. It made removing the cabling from each room and outside wall really easy.

You can't plug a TV into the Virgin Media box. It's a cable terminal, so you will need a VM unit (e.g. TIVO or V6 box) to use it with a TV, or a modem such as a superhub to use it for cable broadband.
