You may think it was similar to a consumer unit if you put a couple of MCBs in it.
Probably better counts as just an isolator if all you fit is a double pole switch. Empty, it is just a metal box.
I would not want to see one before or containing the incoming RCD on a TT installation in a damp cellar or a stables though.
It looks pretty now, after a few years I'd be far less sure after rust has burst the paint, and all gaps are filled by a thick crust of slightly damp straw dust held by cobwebs.
I have seen enough rusting 'Old Bill' and similar era cast-iron kit in old farms and churches, still live and hard to make safe, in various states of decomposition, to put me firmly in favour of non-corroding enclosures for the very sort of locations where the TT supply is most common.
Much as the DNOs are a law unto themselves, I think they are right in this, and there are good reasons that service heads, meters, henley blocs and DP isolators are plastic bodied, we would do well to remember it. In a centrally heated semi-detached house with TNC-s earth, we do not need to worry so much.
