Depends on the job and who you might potentially come into contact with. My line of work only leads to me dealing with back door staff so I only had to have a basic check. This didn’t show the conviction I picked up for fighting when I was still a juvenile.
However, I filled out an Aldi application before and they ask for a Standard check which would show it up. This is because Aldi stores contain the public and I could potentially come into contact with children and/or vulnerable adults thus requiring a more stringent check.
From what I’ve read a company has to justify a check higher than a basic. Tell your mate he’ll be fine. It might count against him in some peoples eyes but he will certainly get a job somewhere.
