Thread: Pistol Storage Rules

If it's not certified (the "approved in writing generally" bit), you need to get it inspected by the Police (the "in the particular case by a member of the Police" bit).
It's probably not legal until it's been inspected, so I wouldn't have pistols in it during the inspection...

As Makros said, talk to your arms officer, at the very least it shows you are trying to do things right.
