MBPC I take it that this picture shows the Gas/Water entering the property & thus no MBPC required

Plastic incoming supplies should not be bonded usually, as shown in the picture you posted

Agree but usually the gas meter sits outside then metallic pipe enters the building
ive not seen Gas entry like that TBH

It's still, usually, part of the dwelling though and only directly connected to external TF via the poly pipe.

I’d say most houses I work in have the gas meters inside somewhere. Under stairs, in the garage, in the kitchen/utility room, in a plant room etc.

It’s only the more recent properties that have meter boxes externally.

Really… all the new houses are external

I don’t work that much in new houses!

It is just a representation to clarify the difference.

So does a combi boiler pressure relief pipe. The point is surely whether the copper is insulated from the mass of earth and likely to introduce a potential or not.

Every one needs looking at from that perspective, but in general if it's wall mounted and a plastic supply then it's usually ok.
If it's sunk into the ground or sitting on the ground then more often than not I end up bonding it.

I had a house recently that had gas meter in separate garage, with plastic incoming gas main, but copper service pipe from meter running underground to the house. That would introduce a potential in the house so I bonded it, irrespective of the fact the supply was plastic.

Recently had a job where I applied bonding to a metal pipe at the stop tap before the plumber had
plumbed in the boiler and kitchen.Came back weeks later and metal stop tap was under the floor with new plastic pipe joined on and new stoptap.Should main bonding be disconnected from the old
stoptap since cannot be touched?'

My old house, most of the town in fact had gas meters outside in those annoying and itchy af fibreglass boxes, only DNO head was inside, typical in the kitchen utility cupboard, and these have been around since the 60s
