Kill the power to it immediately. Something serious is wrong.

Probably because the earth has been exported to some way from where it's
actually earthed.

Pay no attention to that man behind the curtain.

That is what I was thinking, I assume the earth supplied by the power
company is actually connected to planet earth at the substation, this, I
assume, is quite a way away from the house, so some current is flowing to
planet earth via the shorter route. So the solution is to install an earth
rod near the tub?
