I understand you cannot hide cable, eg 2.5mm T&E behind the skirting board but is it okay to put it on front of the skirting board in a trunking? I'm confused as you can buy a mould trunking that goes on top of the skirting board but isn't that a hidden danger? Can't see what's the difference if it's behind or hidden in front If not, then I can go another route but it's a lot more work
