Hi, i am currently boarding out mt loft space and having ripped up the old floor boards and exposed into the eve's there is a spiders web of cabling. what's the best way to tidy this up? i'm not a sparky at all so wondered if i could just extend the cable lengths using Scotchblocks so they were all long enough to bunch together and clip to the sides of the joists as one mass rather than having to "sister" the joists to give clearance over the cabling as the headroom is not that good as it is
