A bit more info needed....is the problem......high earth loop impedance reading?
Not quite sure mate, he just wrote 'resistance to earth' on the form he left with me, this was under the heading 'for all situations the following remedial works are required.'
He plugged some contraption into the sockets near the boiler, that's when he said it needed sorting.
Just to add, I've had a service contract with BG for about 5yrs and although nothing has been changed they have never flagged it up before.
Sorry I can't give you any further info.
It sounds like 1...the earth has been lost or come loose somewhere, it could be in the socket/spur your boilers connected to, or in the boiler itself, but I am sure your engineer will have checked this, but ( to check switch off your electric to this circuit if your unsure switch the lot off, now check all green/yellow wires are connected tightly and in place)
2....it could be the circuits earth at the dist board that the socket/spur your boiler is on is connected to, (to check switch off your electric carefully open the dist board and check all green/yellow cables are connected tightly and in place)
3.....it could be the earth for the whole installation, if this is the case you will need someone with an Earth Loop Impedance tester to check your installations Ze (external earth loop impedance) and if there is a problem or a high Ze reading this could be due to your service providers loss of its earth somewhere before or at the point it enters your property making it the responsibility of your electricity provider to rectify
The one thing I will add is if the installation has lost its earth, it is a serious issue which needs correcting ASAP and if you contact your electricity provider they will respond accordingly and quickly
Hope this helps
