Thanks WWWombat.
We've been trying to identify any potential problems, and are fairly confident all those you've suggested are not applicable to our particular cabinet. We're in the process of setting up a website -
fibre.everestpark.org.uk - to document the cabinet, and how obvious a candidate it is to be upgraded now, and have some evidence ruling out many potential problems on the site.
We've not widely publicised the site yet as we still have some photographs and graphics to add to it (eg/ shots of the 4 existing FTTC cabinets along the same main road with our cabinet or development in the same picture - all are within about 300m of our development (two within 100m of my house). Once that's done we plan to leaflet all residents to highlight the website and gauge how many people actually would expect to buy a fibre service it were available. We then plan to highlight the results to Openreach, the local council, and the developers of both phases of the development to try and get some action.
The PCP itself is on an area of grass verge besides a county council maintained road, and we fairly sure the grass surrounding the cabinet is maintained by the council. There is plenty of space for a fibre twin adjacent to the cabinet, and power 'on tap'. The second (final) phase of the development was approved in 2009 so eventual number of properties has been known for some time - all are now complete; the first phase was built before 2009.
