Hi
As it currently stands, only the ISP can contact Openreach to raise a fault ticket.
That ticket will be created (generally), on the back of a 'Remote Automated Test' (RAT test) performed by BT's fault reception desk, and the results of that test will dictate which kind of ticket to raise.
If the HR fault is developed enough, the RAT test should 'find' its location very easily (ie: fault is in Exchange, E-side, D-side, premises) and the ticket will be sent to OR requesting the right skilled engineer to attend.
If the HR is in its infancy, then there's every chance the RAT test will fail to find the fault and a home engineering appointment would be the next step.
Couple of things though, you say '
All homes connected to the PCP have the same problem' .... that's quite a bold statement considering the number of premises connected to that PCP, plus OR have a system in play that instantly captures what are classed as 'Common faults' .. ie: faults in a similar location.
If there were so many customers experiencing the same issue, believe me when I say Clive Selley himself would be in attendance, as the 'tails' report that is a mahooosive measure within OR, would be sending alarm bells ringing all over the place !!.
Also, OR have a triage system in play that captures multiple repeat reports from the same customer - please believe me again when I say these kind of things get looked at at a far higher level than if it was a first time report.
If you contact the chairman's office as Burakkucat as mentioned above, the first thing they will do is look at these kind of historic events/common fault queue's.
Regarding FTTC - no, there isn't a VDSL cabinet feeding your locality. Sorry.
