Are you hoping for an infill cabinet?
I've only ever seen them install infill cabinets to help cover properties who don't get "SuperFast" speeds (24Mb).
Having a quick look the majority of PCP 39 looks to be well covered by the existing cabinet.
Are there any parts of the cabinets coverage area that get sub 24Mb?
What's your current sync speed?
I take it that G.Fast pod is of no use to you?
If you currently get 30-40Mb+ then the chances of you being part of a network rearrangement are extremely slim.
Quite a lot of one estate has problems with speed issues,including me, speed as low as 12Mb one day maybe 40Mbps the next day,I managed to get my line move from front pole to back pole, now getting around 74Mbps.
As to G Fast, touchy subject, houses at bottom of lane can get it,(DSL Checker 303-166Mbps depending whether clean/impacted line) I can't get it due to silly cable routing adding about 150mtrs or so, to my distance to cabinet.
