Is it permissable/advisable to connect an electric towel bar using a
fused spur, connected to a spur? That's what our electrician intends to
do, and it doesn't sound right to me (I'm hoping he's right, and I'm wrong.)

A spur off a *fused* spur is OK ...

On the fused side, but not from the unfused side only protected by the
32amp MCB!

Don't know what the wiring regs say about it at the end of the day adding say another double socket to an existing one on a spur is no different than plugging in a four socket extension lead into a socket. I suppose if you feed your spur off a FCU then you can control the maximum current drawn by whatever you plug in by what type of fuse you put in the FCU making sure it is below the rated maximum for the cable.

I have seen it done, in our first house a 1975 build there was a spur in a studded wall that ended with a faceplate in the the two bedooms either side and it was simply spurred off a socket on the landing and it was the original wiring done by the builders.

Probably done after first fit before the house had exchanged contracts.

prospective purchaser asked for extra sockets and it could have
been any of the site workers who did it, and not necessarily a
qualified electrician.

And it's probably a "safe deviation" from the regs from a unfused spur

Then that wouldn't be what I'd call "off"

And the protection offered by the known loads.

For a general purpose socket spur, then yes but only if both sockets are
protected by the fused spur.

With a specific known load - like a towel rail fed from a flex outlet,
then it might also be acceptable from an unfused spur if you can show
that there is not possibility of overload.
