Re-routing cable outside property

I have my fibre cable run from the back lane of my property, pinned to an outside wall running along the wall, around a side gate and then around the outside gable wall of the house into the house. I'm having some work done on the gate \ side wall which will need the cable re-routing from where it is, or, the tidier and easier option would be to run a cable from a newly installed cabinet on the street oputside the front of the house. Ive confirmed its a virginmedia cabinet but how do I find out whether its ready to have live installations running from it - it'd be by far the easiest and tidiest option but trying to ask this question through customer services hasnt got me anywhere. Any help appreciated.
