Correct me if im wrong but im sure in the corgi regs it states that you are not ment to bond the gas inside the gas meter box. How many times have you seen inside the gas box and the gas engineer seals the hole that the gas pipe goes through then Mr electrical comes ago and drills a nice 16mm hole straight in the back of the box to get his 10mm earth cable stick it in the hole and not sealing it???
We have all done it???????????????????
