    Derating cables laid on top of loft insulation

    Thanks all for your thoughts. As i said cable is on top of insulation and not underneath. Very hard to clip to anything as there is no slack to move cable so basically just sits on top. Wonder if there is any merit in placing in some big trunking, 50mm x 50mm, but again what reference method...

    Derating cables laid on top of loft insulation

    No the cable is just laid loose on insulation. Dont think there is enough slack to clip it to joists

    Broken CPC on Lighting Circuit

    It's been very badly designed with approximately 4 lighting circuits doing only 2 rooms each. Sounds like my best bet is too run a new cable from the CU no matter how diificult

    Broken CPC on Lighting Circuit

    Maybe I'm not explaining very well, apologies. Yes I need to get a good Line, Neutral and CPC to replace broken cable and the way I see it I can achieve this in 2 ways. 1. New Cable from the CU 2. New Cable from the Loop out from an existing Lighting Circuit. Does this make sense?

    Broken CPC on Lighting Circuit

    Broken CPC is "en route to first light switch" but it is looped at the Switch, therefore feed from CU starts at this switch.
