Frequently asked questions

Is availability the same as take-up?

No. The source counts premises that can get gigabit broadband, not those that buy it.

Why does the map cover only three postcode areas?

Because the source layer does: it holds the NR, PE and IP postcode areas and one Cambridge postcode.
