Can I drill anywhere on this wall?

Are those detectors really any good? Will they only detect metal?

I have one from Screw fix that will detect AC Volts

As above, but really it's not hard to fix plasterboard, so cut down the length of 2 studs with a Stanley knife, in the area where you wish to fit the accessories, cut horizontally top and bottom and remove that rectangle/square, and then you will have a very good view of what runs where. Take a pic of the void for future reference, put the plasterboard back and fill it, sand and paint.
Never be afraid of opening up walls! It's not rocket science...plumbers do it all the time!
(Mind you, they use hammers, and leave it to the plasterers to make good...)
