Main equipotential bonding (water)

[dazw]

Am currently having new kitchen built at rear of house and the main incoming water is being moved to this room.
I need to get a 10mm2 earth bond from this pipe to the main earthing terminal at the front of the house.
Can anyone suggest away of doing this so that an unsightly earth cable isn't seen going up the wall in the corner into the ceiling. Walls havn't been plastered yet so could it be put in channeling or is this not recommended i.e does it have to be accessable.

The 2 ends of the cable need to be accessible but not the entire length. Capping would be fine as long as it is run in the safe zones as required by Part P
