Quick question about spurs / FCU

Am redoing the kitchen and need to add an extra double socket on the other side of the room ( so putting it into the existing ring would be awkward ). This is in a bungalow, so all the wiring is in the loft.

I already have one spur ( from the main ring ) which is running the socket for the boiler and nothing else ( just has a double socket on it ).

If I took this spur, first ran it into a 13A FCU ( before any sockets ), would it be OK to add the one double socket for the boiler to this, then just connect the new double socket ( will just be running a kettle ) onto the first socket ?

I know you arent supposed to run a spur from a spur, but if it is going into the FCU first, so is protected, would this be OK ?

You can run as many accessories off a fused spur as you like because the current is limited by the fuse. If you have good loft access you could even put your FCU up there - an easily seen and accessible position on a purlin is ideal.
Thanks, as the socket for the boiler will be in a cupboard, am planning on fitting the FCU in there are well - as it will only be running the two nearby sockets it should be easy enough to find in the future if there was a fault.
STOP! the boiler needs a maximum 3a fuse!
you cant put a 13a fuse in then feed the other sockets as well as the boiler!

(if thats what you were planning)

edit....didnt realise the boiler was on a plugtop (that needs to be 3a)

Yes, boiler ( oil boiler ) isnt hardwired into the mains, its plugged into the double socket. Its the same plug that was used when the boiler was fitted, and when it was checked and services a couple of months ago, so think it should be fine as the fuse in the plug is protecting the boiler.
