I want to put a shelf across here in my cupboard under the stairs, will be required to hold about 10kg. Wall on the right is a piece of plasterboard ~12mm thick with, I think, a void (possibly with a fair few electrical wires) of about 35mm behind it.
Batten for sure, those fixings will pull straight out of the plasterboard.
Left you could do upside down L brackets, but make sure the screws don't got through the stair risers.
Take care around the switch, the wiring will either go straight up or down (hopefully).

Any suggestions on the best way of fixing it? Just wondering if half a dozen of these

would do the job or I need to start thinking about battens and the like. Cheers
