Hi, I saw your post regarding the ACRO, if your report says "No Live Trace" or something other than "No Trace" - you will may need to get a Full Access Report from ACRO - They are free but take 30 days......
https://www.acro.police.uk/subject_access.aspx
It will show INZ the details of cautions etc. I had a misdemeanor from 20 years ago that was no longer visible on my record any they required the Full Subject Access.
I had character references from members of the medical community in which I work and the community in which I live vouching that I am an upstanding member of society and have been for the last two decades
Good Luck x
