How is the current copper service delivered ? , if it’s overhead from a pole , it’s a waste of your time and effort putting duct from your curtilage to your house wall , the FTTP service will be the same as the existing overhead , so from the pole …..if you are in a underground but no duct area (so DUG cabling) and you have installed your own duct , it may be suitable or you may (for example) have put your duct entry further away from the direction the excavation will come from , in respect to the CBT jointbox and to use it woukd add extra metres of footpath excavation to reach it , in which case it’s of no use .
You can’t discus this with BT (presumably BT your choice of provider) it has nothing to do with them , you order , Openreach visit , if you can’t agree to a provision method (this is only if it’s an underground area with no duct ) the order will be cancelled, if it’s overhead and you don’t want that , don’t order , you’ll only be wasting everyone’s time , including your own.
