UK Water bonding in gas meter box

Just had a boiler put in on a grant scheme.

Water main earth bonding was connected in with the existing gas bonding's pipe clamp on the outlet pipework of the gas meter inside the meter box, then taken through the backplate of the gas meter box, then goes along behind the units to the water stop tap location inside the kitchen.

"at risk" for gas ingress as far as I can see.

To be clear about obstacles; the bungalow is all done in laminate floor over floor boards with no ready underfloor access and this part is an extension in concrete floor;
The previously installed main gas bonding comes from through the loft and down the outside wall. It is the one that comes along the wall to the right of the gas meter box and up through the meter box bottom entry.
To be clear the bottom entry edge is pinched out for the gas bonding cable to enter not drilled or pierced.

There is a corner kitchen cupboard unit on the other side of the wall in these images.
The gas pipework entry isn't visible as it's behind there, though I suppose that would have been the preferred gas bonding location in an ideal world.

So as it stands the water pipe bonding cable currently comes through from gas the meter box, underneath and behind the units then to the stop tap location.

Are there reasons why this couldn't come through the wall elsewhere on the same mortar line perhaps to the right of the box and connected to the gas bonding cable outside of the meter box? If so would this be prefferable to going through the box bottom entry to the gas bonding clamp again the same way as the gas bonding cable?

Is it hard to do a sleeve perhaps under the existing units?

Also Interested to know a bit more about the bonding in general and with regard to the boiler installation.
Any info or thought's appreciated.

Thanks.
