Looked at a job recently where a gas engineer had advised the above as a 'non compliance'.
The meter is external to the property (small block of flats) but incoming gas service pipe (copper) to the flat (second floor) has been bonded within 600mm of entering the flat. (Not easy route from internal service cupboard to ground floor meter!).
There doesn't seem to be a 3 tier system like the EICR to determine compliance (saftey) with the gas report but I advised the landlord from an electrical pov, it would be C3 at worst which is declared 'Satisfactory'!
(The recent EICR was just ticked!) The LL will take up the issue with the gas engineer/company.
Agree?
