Priority CoS request — sharing our format in case it helps someone else
Posting this to pay it forward because we got our priority CoS requests wrong a few times and were effectively ignored. Once we got the filename, capitalisation, punctuation, subject line, email body and timing consistent, we sent the request at 6:58, 6:59 and 7:00 and received an acknowledgement within a day.
This is our experience, not an official Home Office template or guarantee, but hopefully the format helps someone else.

- Timing
Our successful attempt was sent thrice, at:
6:58 → 6:59 → 7:00
We then received an acknowledgement within a few hours.
I can't say that the timing itself guarantees anything, but it was part of what we did on the attempt that finally received an acknowledgement.
