Hi londontech, thank you for your response.
What do I need to say to my estate manager?
I don't think that the house next door to me actually has cable, it just lists it as possible on the postcode checker. There are a couple of houses along the road that do look like they have cable. I was wondering if they'd be able to go from where ever the connection point is on the road (which is cabled) up to the side of my house, I don't think I'd need to share a point with anyone, I just want a unique line going to my property which is adjacent to the road which is cabled (it's just the front of my house which is on the estate).
Thanks again, I'll try this route if there's no other option as I don't really want BT Vision and can't get Sky.
