In many countries around the world, it is advised not to clip your cables to the studs in a drywall or similar situation, the reason being that if someone drives a nail or screw into the wall, the cables are reasonably free to move out of the way of harm ... whereas if they're clipped/attached firmly then the screw or nail is more likely to damage the cable. I imagine this has been discussed, and possibly even advised about, in the UK, but I've yet to see anything in 'the rules'. Thoughts? Opinions? Pointers to regulations?
