From https://www.historicengland.org.uk/listing/the-list/data-downloads/ I get:

I 9,159
II 337,560
II* 21,405
 
but there is little information: The unique ID, grade, date listed, date altered (if any) and a najme that can be "20 AND 20A" with no road.
These have Easting/Northing which I have converted to lat/long.

I am chasing this up to try and get better names and addresses.

I noticed several items that have 'National Trust (with link) in the text but not as an attribute in Wikidata.

I suppose there are no simple tools to identify and correct these?

I am chasing the National Trust for their data. I'll keep the list posted if I get some :-)

Thank you all for your time.
