Yeah, once I've got a way of (semi-)reliably matching entries together
I'm definitely doing to differentiate between:
 - Those with a matching address and a postcode already in OSM (push
these to the bottom or grey-out)
 - Those with a a matching address but no postcode in OSM (make these
more obvious)
 - Those with no match (allow to search by postcode to find the area)

I'm expecting that there will be lots and lots of false negatives
(places where I can't match two things together, even though they
should be) and perhaps a few false positives (due to, e.g. finding the
wrong 'High Street') but we'll have to see. The whole process is going
to have to be quite involved and manual I fear.

I'm also now looking at the Companies House data. There's a hell of a
lot of data there and I'm currently thinking about how best to analyse
it.
