Without following the detail of your particular case the object of bonding is to ensure that all metalwork within the house is at the same potential. Hence the main equipotential bonding from the main earthing terminal is to the customer side of the gas meter and the house side of the water stopcock. Usually in 10mm cable. Cross bonding as required to hot water etc. Usually in 4mm cable. Though actual sizes need to be checked with the wiring regs.
