I am aware of UK differences, but no longer current on the content. I used to be quite fond of those, as in my opinion they showed a good understanding of ATC to flightdeck work relationsip.
Historically, when I used to operate in your airspace, I did well with 3rd party material (Jeppesen) and CAP 413. What you say is indeed news to me, and I already put CAP382 on my to-learn list. Thank you!
fellman The problem with Bulletin no.15 is - from my point of view - that it conveniently omits certain sentences from regulatory guidance. Exactly the one provided in Bigears' quote:
when the pilot is made aware of another aircraft at or approaching an adjacent altitude or flight level
