see regs note below

5.7.2 Fixed cables
PVC cables must be protected against direct exposure to sunlight. Cables must be perminanently fixed in a protected location or mechanically protected or buried.
Later on in the same chapter it states -
Cables need to be shielded against prolonger exposure to direct sunlight, particularly grey and white PVC cables. Cables with a black or rubber sheath are recommended if direct exposure cannot be avioded. Ultraviolet light from the sun will degrad pvc unless shielded will need replacing after 15 years. Black pvc and rubber cables have a resonable life outdoors.
