I have lighting in my loft but need to put power there as well to run my trainset. How do I find a suitable live cable to extend this up into my loft space? My home is about 40 yrs old & has straw walls, which I think has the circuits currently running under the 1st floor boards, then up to the few sockets that are in each bedroom! These boards are 6 x 3 ft sheets, so I cannot just lift them to find a cable & with the walls being straw, I cannot bury a cable in the wall ?
Is there a known way around this as I would sooner NOT have trunking running up the bedroom walls?
Any advice or directions would be very welcome?

The traditional way is to use mineral insulated cable in the corner of the room which because it is both smaller and stiff can be made to blend in better, however the skill required means this is not a DIY job.

However the new alitube cable is very similar in many ways, this may work for you hiding the cable which is round better than with flat twin and earth.
