If it's still plugged in but has a supplementary fuse in an FCU
etc, you can bet your bottom dollar that it's still the fuse in
the plug that goes...

You could use unfused 15A round pin sockets off a fused spur.

Myself, I agree that having the fuse in the plug isn't a problem. I used a
20A DP switch instead of an FCU to avoid having two fuses, and allowing a
more pretty grid switch based solution that wouldn't take up too much space
on the tiles.
