Thanks, Patrick. I did think that it was unusual to simply ignore the
accessibility. The map is for mobile phone coverage down to individual
postcodes, so I can't see that the map itself can be made practically
accessible. However, they do have a postcode search facility that does the
same thing, so I told them that this would be fine, alternative means and
all that. So, with this alternative in mind, what do they do about the map?

No, you misunderstand. The quoted text refers to the main image itself, and
that your text alternative for it at least knows in very broad general terms
what it is (in your case, "Map of the UK"). The actual functionality of the
map itself must still be made accessible (either directly, or provide an
alternative such as a table or just a flat separate page that lists all
areas of the UK and provides that information you'd get when clicking on
In short, the text you quote does not absolve you from making this map
