I forgot to comment before: From a maintenance point of view, is it a
good idea to add redundant data (that I assume are implied by HE_ref)?
The HE_Ref is probably the important one, as that links back to the
original data source. But the rest of it seems a reasonable way of
tagging listed buildings.

Yes, maintenance when things change is an issue.
I've looked at taginfo listed_status and found several variations
for
Scheduled Monument, Grade(value)
I plan to do several things if there are no objections
1. update wiki listed_status to show the capitalised values
Scheduled
Monument, Protected Wreck Site,
Park and Garden, Battlefield, World Heritage Site, Certificate of
Immunity, Building Preservation Notice
What happens to, say, a park/garden with a grade, then?
Parks and Gardens are, typically, not listed buildings and don't have
grades in the same way.
Straying a bit from the topic a bit, perhaps it's worth adding
something about adding listed things that may not be obvious to
everyone. If you find in the HE listings a building (say) you don't
already know and want to tag it, presumably it's a problem that you
can't just match the position on their OS maps to OSM. I assume you
need to take the listed grid reference and just use that (which you
probably can't with curtilages etc. or a monument like an ancient
ditch, though that's likely on NLS 1:10000). The wiki could use info
about converting grid references too, unless I missed it.
The re-usable data for listed buildings only contains a point, so that's
the only useful geographic data for them even if the map on the HE
website shows the curtilage. Some of the data for monuments includes a
polygon, but not all, and you can't tell from the website which does and
which doesn't - you have to download and convert the shapefiles.
