Laying cable in the garden for lighting

[breezer]

ok, ok
lol
How about I take the wire accross the wall at say a metre high, is that legal?

then run it down the wall under the coping on top of the wall of which the light unit will be bolted to?

no, because twin & earth will degrade if exposed to the elements

you could always use plastic conduit though (for going along the wall)

Make sure it's black, then it is UV protected.
