Hi, before I waste an electricians time by calling him out… I wanted to check if it is possible to add an independently switchable light to my landing, without having to have a cable run from the light switch downstairs (so I can avoid channeling into the wall etc.). The red is effectively the drop down light I want to add and the switch in blue is where I’d like to be able to turn it on and off from - separately to the other landing lights. Currently that is a switch of 3 - outside light, downstairs hallway lights and landing lights. No idea on electrics, so don’t flame me - I’m just asking if it is possible ! Thanks in advance.
You'd need another switch wire, very much doubt you'd have a spare core. If you have id have a go on the lottery You can do it with wireless switches, I've never used one but I think its quite simple, someone will advise you soon.
As @Ind spark says, you can use a wireless switch like this: https://www.tlc-direct.co.uk/Manufacturers/Quinetic/Quinetic/index.html You'd still need a permanent live at the light fitting to fit the receiver although it looks like you have loft access nearby.
