I am looking to install 4 5A round pin sockets on the lighting ring, so we can switch on lamps around the room using a switch by the door. I have 2 questions; Wiring and Fusing.
Part 1 – Wiring
How should I run the wires to each of the sockets?
Option A. Seperate wires to each (My prefered option for ease)
Option B. Wires between each socket
Part 2 – Fuses
Do I need to add fuses to any of the sockets or plugs?
The reason I ask this is Screwfix has the plugs and sockets, but they do not have fuses is either sockets or plugs. (But are still listed as 5A)

There's no such thing as a lighting ring in UK domestic wiring. Lighting circuits are radial. (They run out from the fuse box but don't return to it.) If you are taking power from one of these you don't need additional fuses - the fusebox already provides the needed protection (5 A fuse, 6 A MCB). If you are taking the supply from a 30/32 A ring circuit you'll need a fused spur unit fitted with a 5 A fuse. (You are likely to need to buy this with a 13 A fuse and replace it.)
You can use either option to wire the sockets. Note with option 1 you'll need to use a sufficiently large ceiling rose cover to accommodate all the connections (or run them from the switch on a suitably deep backbox). Wago connectors can be useful for hooking everything up. Apparently 2 A plug/sockets are OK to use on a lighting circuit but the larger 5 A ones are easier to wire up.
