Territory
Because the boundaries that matter in this trade are the network operators, and they do not follow the regions anyone thinks in.
Every homeowner who fits one of these has to notify the operator that owns the wires in their street, within 28 days. Knowing which one is a small thing you can do for them that nobody else will.
No postcode lookup goes out from us until every one of these areas has been put through the operator's own checker. Ask the operator in the meantime.
The network is new, so no area is spoken for. That will not stay true, and the areas that go first will be the ones where somebody asked early.
Tell us the postcode prefixes you actually cover rather than a county. A trade contact who says they cover the South East and means four postcode areas is no use to a homeowner in the fifth.
Give us your postcode prefixes and we will tell you what is open.
Tell us the trade you are in and the postcode areas you cover. We will come back with what we can supply in your area and what it will cost, once the network is carrying enough traffic to promise anything. We would rather tell you later and be right.
