Hey Steve,
I'm the Engineering manager for Moz Local and wanted to follow up on your question. We are working to address a couple issues specifically for UK listings in the next week or two:
1. Address verification: We are working to improve our UK address parsing and normalization which should address a number of issues around being able to purchase listings.
2. Address comparison. As Matt mentioned, the slight inconsistencies you are seeing do not have any signification effect and we are working to account for them. Note that the address inconsistencies displayed in the listing report do not affect our measurement of accuracy for a particular partner in the Moz Local dashboard.
Cheers.
