Gas Bonding to MET or consumer unit

[Martin58]

sorry if this has been covered but I cannot find answers -

1st floor flat TNS supply from basement - the water is bonded at the stop cock within the flat to the consumer unit .

The Gas enters in 2 places for cooker and boiler . Some "brightspark" has earthed this via a rod at the meter - does the bonding need to go back to the MET in basement or is to the C/Unit ok ?

Hi - if the flat’s water is bonded to the flat’s CU from where it enters the flat, I’d do the same for the gas. I understand 2 gas pipes are entering the flat, so I’d bond both. If I’ve understood correctly the gas supply to the building has been put to a rod? I’d probably bond that gas pipe to building MET in the basement.
