There are various ways of extending a lighting circuit to add lighting points: You could run a spur from the last ceiling rose in a loop-in circuit; run a spur from an existing junction box, or from a new junction box; or run a fused spur from a socket outlet.
To connect a new junction box, you will need to locate the circuit cable connecting roses and junction boxes. To trace the correct cable, lift the floorboards or gain access to the area directly above the ceiling.
If a lighting circuit would be overloaded by the addition of another spur, you can create a sub-circuit by running a spur from the ring main circuit or from a socket outlet to the lighting point via a fused connection unit (FCU).
