Hi all
I need to install supplementary bonding in both kitchen and bathroom,
as there isn't any at all at the moment! Two queries arise please...

1. I have the luxury of having no ceiling at the moment in the room
below the bathroom, which means all the piping is readily accessible.
I could very easily install earth clamps connecting all the pipework,
very neatly and invisibly. However, is that allowed? Do you need to
be able to see the clamps etc in an installation? Where exactly do I
need to attach the clamps; as close as possible to taps/radiator etc?

You don't need to be able to see them, however they do need to be
accessable.

2. I need to take an earth cable right through the house to the
kitchen sink. Do I need to have a separate, continuous cable going
from the earthing point at the fusebox all the way to the kitchen
(which means going through the bathroom en route) or is it sufficient
to piggy-back the kitchen earth cable on to a clamp on a bathroom tap,
say?

You'll need to run a 10mm earth from your meter position to all of the
incoming supplies, gas, water, etc.. directly, no joining or
piggybacking.
You''ll also need a 4mm earth around the pipes, radiator and all other
metallic surfaces in the bathroom.
And assuming your water supply is under the kitchen sink, you'll also
want to run a link across the hot and cold, (and sink if it's
metallic), in the kitchen.
There are some nice colouurful pictures on the web somewhere but I
can't seem to find them at this time!!
