Hope this question makes sense - I'm not very up on how some of this stuff works, or the terminology for it.
So we moved house recently, and our broadband speed (we're with EE) is very slow - about 5mbps, I think.
We had an electrician round for some wiring work, and he told us that there are two broadband wires running into our house: an old one, which is what we're plugged into, and a new one ('a twisty one' he called it) that goes into the loft, and then stops there. However, he tried to connect us to the new wire and found it didn't work. He called BT, who told him this line was for BT broadband customers only. (The wire I think comes from the green phone exchange box thing on the corner of the street.)
Have BT got this right? Can a wire be reserved for use only by customers of a particular broadband provider? It doesn't seem likely to me that everyone on the street is on BT. If we did move to BT to take advantage of the fast wire, would we have to stay with them or could we then move to a different provider again? If we went straight from EE to a non-BT provider, would that provider have to run yet another wire into the house?
I hope this makes some sort of sense. Thank you in advance for any help!
