Splicing a BT fibre

Hi All,
We have a customer with a leased line provided by a BT blown fibre and they need it rolling back within their premises to a room where the blown fibre tube currently passes through. Is it possible for us to cut where it is currently spliced, pull back what we need and re-splice in the new location?
Regards
Mark

Any changes to the line will need to be done by BT. You need to contact them and tell them what you want and they will give you a quote for doing it.
