So my query is: If the fitters had installed £77 worth of "additional
earth bonding" where would this be likely to be located?

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.
