Hi - I would really appreciate some help with this, thanks: We
recently had a new bathroom fitted, nothing fancy, just a replacement
bath, sink, loo and electric shower. Although we were only ever shown
a single, final figure for the work the fitters left an itemised job
sheet lying around showing that we have been charged £77 for "fitting
of additional earth bonding".

Now, I assume this refers to the fitting of the shower as this is the
only electric work we have had done (all new plumbing is plastic so
isn't earthed) but all I can see is a wire going from the shower,
through the floor to a newly fitted RCD and then into a junction box
below the meter (we have an old on/off box, the shower is the only
thing on an RCD).

So my query is: If the fitters had installed £77 worth of "additional
earth bonding" where would this be likely to be located? Because as
far as I can see all they've done is fitted the shower which was
billed as a separate item anyway.

Again, thanks for any advice.

It would either be

a) equipotential bonding in the bathroom, often misdescribed as earth
bonding. This is a 4mm insulated cable connecting various metal bits
in the room

b) or it may be earth bonding at the meter, or from meter to mains
water supply.

a) is "supplementary equipotential bonding" and b) is "main
equipotential bonding" and neither should be described as "earth bonding".
