But still after it's entered the house
Not so. within 600mm of the meter outlet union, OR at the point of entry to the building if the meter is external...
544.1.2
Would you like to tell me the difference between these two statements - bearing in mind the OP said that the meter was outside
I was challenging your blanket statement
The bonding could be made on the gas pipe outside, doesn't have to be after it has entered the house.

Yeah, OK. Whatever that gizmo is that is next to the meter that turns the gas off.
In sparking applications that would be called an isolator, or main switch.
What do you gastronomes call it?
It wasn't a blanket statement - it was specific to this thread
You're wrong! - You've just quoted the relevant regulation in your previous post.
If the meter is internal, you bond on the consumer side of the meter, before any branches etc.
If the meter is external, you bond within 600mm of where the pipework enters the building.
You don't bond outside
If the meter is external, you bond within 600mm of where the pipework enters the building.
You don't bond outside
Read what the reg says. You bond at the point of entry to the building if the meter is external... not up to 600mm away.
And yes you can bond externally. That is what external BS951 earthing clamps are for.
The 600mm relates to distance from the meter if you are bonding at that point.
we can say if it sounds fair.....
It's only gas fitters who want to see bonding in their external meter cupboard - probably due to the wording of their regulations.
Problem is, they're totally missing the point of 'bonding', as are you, it seems.
Why on earth would you want to bond metalwork/meter outside the building - it could hardly be called an 'extraneous conductive part'.
The only time it would be worth doing is if it were impossible to bond the pipework inside, at the point of entry to the building, so just outside the entry point would be best.

By the time it gets into the meter cabinet it's no longer buried in the ground.It's only gas fitters who want to see bonding in their external meter cupboard - probably due to the wording of their regulations.

By how much is the potential wrt your supply earth going to change over the short run through the wall into the house, and therefore to what extent is your equipotential bonding going to be compromised?
not just a matter of neater. The bonding connection has to be accessible and visible.
It is true that any alteration or addition to the electrics in your house cannot be signed off without the main protective bonding being in place.
As for cost, that depends on your what you agreed with the electrical firm before they started work and how many bacon butties and cups of tea you made the electricians (half chocolate coated hobnobs also go down well)
Visible? Really? Please tell me where it says that?
