You don't have to, but make sure your supplementary bonding is continuous, radiator, buthtub, copper pipes, Electric shaver socket, any exposed conductive parts have to be bonded

MICK101,
you have to run a short lengh of 4mm cable from copper pipe (using earth clamps) suppling water to electric shower and terminate at the el. shower's earth terminal. Keep the bonding continuous, from there (copper pipe) to buthtub, radiator, any exposed conductive parts
