I'd try and negotiate whatever you are paying for FTTP provision under the USO to include the fibre delivered to a CSP on your property. It sounds really messy to be enabling the closest chamber to you and leaving a substantial distance still to cover.
Worst case scenario is you pay the USO charge and then are hit with ECCs, slightly better is you enter into weeks of complaint handling within BT. If there's an opportunity to get this addressed now then that would be my preference.
My understanding of a USO order was that it was a service you were ordering - e.g. an FTTP product of whatever speed you picked, rather than a contract with Openreach, so I can't see how the order could even complete without ending up with a connection in your house.
