I've been back today ( concerned about the " no earth whatsoever TBH )
Made a futile attempt to find a redundant lead water pipe which I intended to use as an earth electrode ....ended up filling the hole up again , have to get my mate to go and relay the block paving
So , 6 earth rods later (Stepps would be proud) I got a reading down to 98 hms Back tomorrow to fit some boxes over the clamps.
