OK , you didn’t make it clear that is wasn’t just your house , your original post suggests it’s just your address, when there are many neighbours in the same position as you.
It can be the case in underground service areas , where ducting between joint boxes in the footpath is unserviceable, a CBT or several CBT’s in a jointbox or joint boxes, designed to service the properties opposite , can’t be ‘cabled’ back to the splitter because of these defective ducts , whereas jointboxes outside other properties in the same street can be cabled back to the splitter node because the duct route for those CBT cables is OK .
In less financially restrictive times , the ‘cost’ of excavation and repair or replacement of the unusable ducts would have been accepted , and the work done immediately to get those properties ready for service, but OR is no more immune from cost restrictions than anyone else and these days it’s more likely that the CBT or CBT’s that can’t be cabled back to the splitter without the expense to repair or provide new ductwork, are simply postponed until budget allows , therefore the designated properties aligned with those CBT’s can’t order FTTP when other properties in the same street whose CBTs were cabled back to the splitter can order service.
FTTP installers work for an Openreach division called SD (service delivery ) a separate division to the network build engineers who work for FND (fibre network delivery) so SD are unlikely to know why some addresses in any area are good to go and very near neighbours are not .
You can fill in this formwize and ask OR to check , there is a part that asks ‘ my neighbour can get FTTP but I can’t ‘ , OR will check and get back to you pretty quickly.
