Hi

I would really appreciate some help with this:

We (foolishly in retrospect) paid a major DIY retailer to supply and
fit our bathroom. I say foolishly because having been promised
(twice) it would be done in 5 days, the reason why we were happy to
pay them, it has actually taken 6 weeks, so far, so we may as well
have done most of it ourselves and saved a shed load of cash.

Anyway, getting to the point, we have, apparently, according to the
invoice, paid £77 for "Supplementary Earth Bonding", now, the only
electrical work we have had done is the installation of an elecrtric
shower. Looking at the wiring, starting downstairs, I see an earth
wire from the meter going to the shower RCD, I then see a wire going
up, through the ceiling, into the bathroom, it then goes under our
bath and into the wall, up the wall and into the shower, that's it.

All additional plumbing is plastic (except the taps), the bath is
plastic, the only metal is our original copper water pipes and there
appears to be no new additional connection to these.

Now I know that earth bonding does *not* mean earthing everything in
sight but does anyone have any idea what we have paid £77 for? I
suspect absolutely nothing!

I'd imagine so, I'd dispute it. I hear many tales of woe about B&Q.
