Welcome to the Q&A Forum

No my client is based in the UK. I'll check for mapmaker functionality on My Business interface. Thank you!

The short answer is "no". Your info in Wikipedia/WikiData is probably fine. Essentially, either: (1) Google doesn't view you as having enough entity authority (for lack of a better phrase) to display more information, or (2) They aren't able to validate that information against other sources. You might be able to nudge them with the Organization schema, although results seem to be mixed. There's a decent article on the general topic here: http://searchengineland.com/leveraging-wikidata-gain-google-knowledge-graph-result-219706 To some degree, though, it's not something you can tell Google to do or not do - they generate these features on the fly and it's always evolving. Best you can do is make sure your information is correct in WikiData, continue to build your overall authority, and gently nudge them in the right direction.

Feedback received! Thanks for forwarding the information Abe
