I have a telegraph pole ,a lamp post and a letter box right outside my drive ..the telegraph pole being right on the grass verge outside my property. Telegraph poles cannot be moved.Even if they did agree it would cost mega money.
Believe me ...I have asked about it !! My son moans all the time about getting his car on the drive but he always manages !
I think if they are actually within your boundaries BT have to pay wayleave or something .
Not too sure on the ins and outs of that one but a swift Google should give you the info.
