In order for you to be able to order FTTP there must be a CBT within 120m of your property, or if planning doesn’t permit one within 320m.
If the nearest one is 1km away then something has clearly gone wrong in the Planning and or Network Build Phase.
Without seeing the Network Map for your Premises theres to many variables to suggest what it may or may not be.
I’m afraid it will literally be a case of wait for an Engineer to visit and they’ll act accordingly as to whether it needs a Dig, Planning, etc.
