is this the assessor?That sounds like the Stroma assessor I had last year. He insisted that any outbuilding FURTHER than twenty metres from the main building needed to be TT.

If thats the case then the DNO should be providing that info when they install the supply or a upto date map online so the information can be cross referenced.To my mind it seems everybody is wrong
Firstly the assessor for calling it a non compliance of the wiring regs
Its wrong by the op (and everybody else here) for assuming this is a issue about those wiring reg being contravened or not
As far as I understand,there can be dangerous situations created by incorrect use of the supply earthing arrangement
Its a "suppliers" stipulation that Pme not be used outside of the equipotential zone without their permission
That permission should be sought from the supplier in order to do so,otherwise its get yourself a rod and provide your own
The wiring regs will tell you how to cater with whatever earthing is used,it does not give choices of what to do with the earthing provided by others and whether it should or should not be utilised
….never seen anything done about it, either.I've seen that line posted a few times 'Distribution Network Operators may forbid their PME earth being exported from the supplied building' (or similar), but I've never seen it actually written in any DNO document?
I'm not sure how it can. Hopefully I'm wrong, but it seems to me a kettle on a 100 Ohm rod will still pull the touch voltage all the way up. Even 10 Ohms gets to 100V .Supplementary 18th Ed earth rods will sort that

I think they where looking for a reading of around 20 ohms for the supplementary earth electrode, similar to that of the DNO electrode at the supply endI'm not sure how it can.

Electrode on the penultimate column.All the streetlighting in Cornwall is on PME.
