Our mains water enters in the cellar & then runs up the side of the
cellar steps. Electricity comes in from the rear to the CU. Hence a
longish run (15m) of main bond cable needs to run alongside the water
pipe between CU and incoming water.

I am about to put Climaflex pipe insulation around the water pipe:
What is the correct way of running the bond cable - ie (a) clip to pipe
and cover both in Climaflex (b) clip cable to outside of Climaflex or
(c) clip bond cable to wall away from the Climaflex? [(c) is the least
convenient]

Thanks for any advice.
