Earth bonding to gas in a large block of flats

[Richsand007]

Hi, just doing an inspection on a large block of flats. All the gas metre are in a single store cupboard on the basement floor. All are 10mm bonded there within 600mm. There is no earth bonding to the pipes entering the flats themselves. Is additional bonding required within each of the flats ie with 600mm the gas cut off switch? Flat is partially RCD protected, 20 years old, no supplementary bonding. A lead test in the flat is 0.54ohms. Would class this as a code 2 or pass?. Thanks
