Besides, the UK doesn't seem all that well off according to what I've read. UK ground is not the same as continental earth. I think it's got to do with the lines being earthed at the station, whereas the continental earth lead goes to UK mains earth is bonded to the neutral and to the earth spike at the local transformer. It should also be bonded to earth at the property and, if the run from the tramsformer to the property is a long one, it will have more earth points along the way (PME - protective multiple earth). A bit safer than a rod in the ground here and one way over there.
