If WF158HH is your postcode, which is the line your pointer was at, then the P27 is the phone cabinet number. That's what you need to find. It should be on it.
In your first link this time, the one on the corner by the white signpost is BT. Rotating, the pair near the speed camera, the small one is VM, and I think the big one is as well.
Rotating some more I see one on the opposite corner to the signpost. That looks like another small VM.
VM has lots of small cabinets like that in an area, served from a big one. BT has far fewer in an area.
Have a look at the pics I have on
this page. In your second link this time, the small green one is BT phone, the dark green with the V-top I think is Virgin and nothing to do with it.
BT numbers are 1, 2 or 3 digits. Only one 4-digit one known about, on Trafford Park, Manchester. VM cabinet numbers are many digits long wherever I have seen them.
You don't seem to have picked up on what I said about Virgin. They will not be working on the BT FTTC, though they may be installing or upgrading VM Cable. Although BT use sub-contractors for a lot of the work, I'm sure they wouldn't use their biggest direct competitor to install critical systems.
