Done a board change this week and discovered the house has no earth(except for the 0.51ohms of the Gas!), all the earths go to the block on the side of the head but there's 0v between the block and Iine, I got the DNO out who said there has never been an earth since the head change 15 years ago, they want a cert before they install an earth, To confirm bonding is present ect, are they after a PIR?
