Earthing conductor route

That’s a 25mm2 earthing conductor run some 20m along a border hedge to an electrode at the rear of the building. It is a permanent, recent installation. When I commented on it the contractor lost his cool and screamed “what the hell is wrong with it”? I thought that the answer was obvious but my written response on behalf of the client is to be framed within the context of 7671. I have no difficulty in digging up the relevant regulations but they are subjective in nature. Anyway, all good fun!

    eventually found the rod below a discarded water tank at the rear of the building. The DNO earthing arrangement was lost and after six months of waiting for a fix, the client decided to engage a contractor to convert to TT. His EIC shows a Ze and Ra of 0.26 but was 127 when I measured it. The reason for the long run is unclear but there were definitely easier alternatives. I originally thought that the fix was temporary until the DNO got their act together but that is not the case.
