Why can you not spur off a spur?
The reason for not running two spurs from the same spur “point” is that it can lead to possible overloads in that one leg of the final can become unbalanced and exceed the max.
How many sockets can I run off a fused spur?

Yes of course, for example desk lamps and other loads can be on the same circuit. However, there’s usually a special circuit for lighting because lighting pulls very little current, and so much thinner wire can be used, and so a separate lighting circuit is cheaper to install.
Can you add an FCU to a spur?
you could put a 13A FCU next to the socket upstairs with 13A fuse, from the LOAD side of the FCU run 2.5mm down to lighting FCU and on down to the double socket. The upstairs FCU protects the whole circuit and it isnt a spur off a spur anymore.
