Where/how should i chase my cable

[processpaul]

Hello all, hope you can help me. (Not ever had to do anything like this before)

I have three cables i want to chase into the walls of a bedroom. They are currently in surface mount conduit.

One cable is for the room thermostat. This comes down from the ceiling about 5cm from a corner.

How far from the corner can i move this to the right? I might need to put a wardrobe in this corner so dont what the thermostat obstructed. Should i chase into the wall brickwork above the ceiling board a little, so that it comes neatly down from above.

The second is from the room thermostat to the electric radiator valve in the room. This comes down through the ceiling but not close to the wall.

Can i go vertically down in the corner and then horizontally along above a skirting board to the radiator valve. (this was the route in surface mount) Or should i go down to the floor and along under that?

The other cable is an aerial cable what should i do with that one?

any help appreciated.

Also, even when in those accepted zones, if the cables aren't more than 50mm deep, or with earthed mechanical protection, they need to be RCD protected.
