544.1.2 The main protective bonding connection to any extraneous-conductive-part such as gas, water or other metallic pipework or service shall be made as near as practicable to the point of entry of that part into the premises. Where there is a meter, isolation point or union, the connection shall be made to the consumer’s hard metal pipework and before any branch pipework. Where practicable the connection shall be made within 600 mm of the meter outlet union or at the point of entry to the building if the meter is external.

Nice one that answered that question just right.
 
Thanks Gas & Water bonded to 1 x 10mm cable? {filename} | ElectriciansForums.net@davesparks. So there is no requirement to provide a bond at the gas entry point to the building :) if one is provided at the consumer side of the meter;)

Generally yes, but ultimately it is up to the person signing the certificate to decide if a particular installation requires additional or different arrangements.
 
I think the continuous earth conductor bonding gas and water was in an edition of the regs from the distant past
 
The bonding conductor would still need crimping or be accessible for inspection if it were joined, you couldn't just hide a terminal block under the floor.
Also bonding should electrically be where the pipe enters the building. But gas has its own special rules about not bonding before the meter, and anyone who removes the meter is supposed to clip a temporary bond on.

It should, but it doesn't have to be.

Gas doesn't have its own special rules about bonding, bs7671 says the same thing as it does for all services, it should be after the meter.

fair point I meant special in comparison with generic extraneous conductive parts. but my actual point is it's not the meter that makes it extraneous it;s the fact that it enters from outside the zone, therefore the OPs gas bonding at the point of entry is actually better electrically
For example because anyone who removes the meter without temporary bonding won't be breaking any diverted neutral current in that case)
