Highly doubtful you'd get your line swapped. I tried with BT, and some local providers when Digital Region was active. The cabinet our house is connected to is about 1.2Km from the house, there are at least 6 closer. The local exchange is between us and our cabinet as well.
Expected speeds for FTTC were low, about 16meg at best. We were on 30meg Virgin at the time.
It's down to when the houses were built and/or when lines were first installed. There has been development all around us in the last 100 years since our house was built. But, your line stays where it was put. I was told it would impact upon neighbours too as they share a multi-pair cable from the cabinet to the nearest pole.
I disagreed with them as the swap should be made at the exchange end, not re-routing from the old cabinet, that would make it worse!
Nobody wanted to discuss putting a new line in from a cabinet just 100 metres away, I had to have service form the old cabinet, like it or lump it...
