Earthing for garage water service?

[SSE]

If a garage that has a 3-core 6mm[SUP]2[/SUP] SWA supplying the power to it & has a small bathroom in it, what size of earthing is required for the pipework for the water? In normal circumtances it's obviously a 10mm[SUP]2 [/SUP]earth in a property but not to0 sure about garage?

Is the garage joined to the property? Or more importantly, is it a continuous metallic water supply fed from the house, is there any exterraneous pipework? Need more info mate, it may not even need a bond.

And - is it actually a 'bath'room?

Hi, sorry for lack of info, safe too say my brain was calling for bed time when I started the thread. The garage is not joined on to the house, it's a separate building. Don't think it's going to be a bathroom, just a toilet & sink, never really though about it but if it's done in plastic pipe no earthing is going to be required anyway. The house is TNCS I'm pretty sure.

If the pipework is in copper, or other metallic material then you'll either need to increase your SWA cable to 10mm, or run a separate 10mm CPC for your bonding requirements....
