One registered part P electrician i got to quote has quoted on 6mm2 armour and mentions nothing about actually earthing it. i assume he was going to just earth it to the houses supply. and a second quote mentions 10mm2 and like wise no earthing rod's so this is what makes me think i'd be better...

yep i do know about part P. Am also looking to actually become a qualified electrician but already running an IT company its finding time to actually qualify. Thanks for all your help.

is just one deep enough though?

Just when you think your getting somewhere, so i really need to find someone to put in the earthing rod. or just put it into the ground till it hits australlia?

And of which i am extreamly thankful :) just one more question to i think set me up and ready to go how deep should i put the earth rod in the ground? Thanks again everyone for ur help. :D

Thanks i'll go with a larger unit and have the 3 supplys plugs, heater and lights. would it be advisable for a slightly larger cable than 10mm?
