You could always move?

Radial distances, yes.

But the pricing document is confusing about where the distance is measured to...

Below the table of price bands, it states the charge is based on the radial distance to the relevant node, not the nearest.

Higher up, it uses the term nearest, but only when mentioning that 96% are within 2km of the nearest node... but it doesn't state that it will be used for setting the charge!

It'll be interesting to see where this goes.
