No one from BT has any clout over OR's rollout of Full Fibre.
Although BT Consumer (the communication provider) and OR are both owed by the BT Group they are separate companies. And as OR provide their network to many communication providers (Sky, TalkTalk, Shell etcetera) they have to treat BT just the same as any of their customers.
OR are rolling out FTTP across the country but they can't do everywhere at once. I presume they prioritize areas based on many factors. One crucial factor must surely be... are their other networks already in the area? If OR put FTTP in a street that isn't serviced by any other fibre networks (Virgin, City Fibre etcetera) then OR, and the communication providers they service, are the only Fibre option in town. But if another company has already laid fibre cables in a street the returns for OR will be less, they will be competing with companies who already have a foothold in the area. So they would be less likely to spend money laying fibre in that street.
Other considerations would include resources. I believe OR have a manpower shortage in the SE of England.
Also getting local authority permission to dig up roads would be needed. And that is not always easy to get. Where exactly in SE London are you?
