So I was at a 2 bed flat today, ground floor on 4 storey block. 3 years old flats. The supply head holds a red fuse holder reading " solid link, do not fuse". TN-S and the CU is just off the bottom of this shot below the 100A isolator. ~75 cm tails.
"Fuse" is all crimp sealed, I didn't pull it, original DNO work. What's going on here then?

As mentioned, I'd expect to find a fuse at the other end of the orange cable.

BUT, if this orange cable combines N and E between the fuse and this dummy head/link, I thought that was no longer permissible?
 
I didn't have time to check further, was only there to swap some mvhr fan filters. Orange cable doesn't combine NE, it's TN-s. Presumably some fusing down the way. Was a bit surprised to see it done this way since the meter is this end. The orange cable must be a sub-main fused..somewhere.
 
I guess it is. Simple answer. - But what threw me was the meter at this end. I guess there's no requirement on the supplier ( not talking DNO any longer) to put their meter in any particular part of their cable. I'm just not used to working in flats.
 
Last time I came across this, the issue was that the DNO owned the head in the landlord's cupboard. And the supplier owned the meter. But nobody wanted to own the piece of cable in between, i.e. the orange cable.
