It would have been a lot neater if they'd used metal isolators and terminated the armoured cable directly into them.
Welcome to ECN Adam.
You beat me to it, as I was going to say just that. Why go to the trouble of fitting the galvanized box and then running singles up to it from the isolators when you could just use a metal-clad box and gland the SWA directly into the top of it?
It would have been much neater and the SWA could have just been cleated to the wall/panel.
The brown and blue cables struck me immediately as well. There were old red/black double-insulated cables in the 1950s/60s which had the outer sheath the same color as the inner insulation, but I wasn't aware that anything like that was being made in the new colors. I've not seen anything except a gray outer sheath yet.
I didn't take these photos myself and haven't seen the installation in question, so unfortunately I'm not able to say whether the orange feeders are MICC for sure or what service equipment is feeding these from below. I know that one of these meters is feeding an apartment on the British 1st (American 2nd) floor. I'll try and find out some more details.
