The data I used is freely available from the council’s website (although not in a very useful format). But, with a bit of copy and paste, some processing through a few tools available on the internet and a Google spreadsheet and voila, a map sort of telling you where is, and isn’t, covered by NW in Wandsworth.
It isn’t ideal, it’s a little crowded at this size, and the Google standard flags don’t really show it off that well. Additionally, because it’s roads it isn’t that accurate. For example, a long road might only be partially covered. Finally, there are a few roads that I couldn’t find – however hard I (or Google) looked.
But I would ask one question: how is anyone’s privacy infringed by this, and how would it be infringed if I used postcodes instead of road names?
