I’m looking into more automated use of the NCPR data, but I don’t think it’s going to be possible for their locations or addresses, are they’re very likely geocoded or derived from non-free postcode data. There are also errors in the data, and it doesn’t mention a load of chargepoints which I believe exist (for example, the LDNPA one in Glenridding).

While the NCPR database as a whole is compatibly-licensed (OGL), parts of it could be more restrictively licensed.

So until I’ve clarified the licensing, I think the best we can do is use Robert Whittaker’s handy comparison tool to inform surveys: https://osm.mathmos.net/chargepoint/progress/
