Asking as my street is down as "in scope" but the planning permission was granted by the local council at beginning of August, and they have marked the pavement where the two cabinets will be installed (street has EO line's), so I would have though the page would display "design" or "field survey".

Postcode is EH478BN and exchange is ESSYB.
