Just looking like, or is it actually on the cooker supply?

Thinking about it, I was slightly sidetracked by the 'Cooker' on the
separate fuse. It is in fact a gas cooker, which obviously replaced the
previous electric cooker, so should be no problems with overloading the
cable.
It is a 30A fuse, with the relevent cable (6mm iirc).

There are no RCDs anywhere in system.

Prior to the 17th edition regs[1], there were plenty of cases when an
electric shower could be adequately protected and safe even without a
RCD.

But wouldnt fitting a RCD be much safer than it being protected only by
a fuse?

In effect - often these are positioned close to the CU rather than close
to the shower though.

Fitting it at the shower end would be far easier, but yes, I suppose I
could replace the separate fuse box for the cooker at the incoming
supply end.
