you should be able to see if it is PME without calling them.
I wont help even if it's not anyway.

Not the same. No.
i like the idea but there just isn't the option to do this unfortunately due to it being a car park immediately outside the building.
I seem to think this is going to be more problematic than planned for.
i think other than connecting the rod to the met there's probably not a lot of choice.

Not to the MET. The rod would earth the VCP only.

Why not? It'll be much better for the installation as a whole to have a decent earth nest connected to the MET than it will to have what is effectively a big external socket connected to its own earthing reference in such close proximity to the metal building bonded to the PME earth.
I guess I could put a rod or two in the base of the unit as looking at it, I'll be able to do this quite nicely, make connecting it easy.

I cannot answer that TBH. Just does not sound right.
I'm so I'll just run 16mm swa to the charge point, connect it to the met, and also connect an earth rod in for good measure.
Ok so we have a plan of action, it says in point two, a rod of very low resistance. Can anyone telld what if says in 722 of the regs as have not got a BYB yet.
I always start with 2off 8'x5/8" rods spaced 10' apart and then test that and work up from there.
The earth electrode(s) should be connected back to the MET, not to the end of your new circuit.
Why doesn't it sound right? Adding an extra earth electrode to the PME supply is only going to improve it and make your installation safer in the event of an external neutral fault. This is exactly what is recommended in the regulations for swimming pools fed via a PME supply and is required practice for PME supplies in other parts of the world.

Wont the fault then take the path with least resistance which is bound to be the PME earth which pretty much makes the earth rod pointless?
