But it doesn’t prevent pipe work from moving in the wall no matter what the regs say, let’s talk real life her instead of theoreticals. You can disagree all you want but even if he sealed it what’s it gonna do? You seem like the expert. I see far worse on the job regularly from “qualified engineers” and wouldn’t be worrying about triviality like this.
I’d say if the person was breaking into a gas line it would be completely different but your making a mountain out of a mole hill here in terms of real life Over something that might or might not be sealed inside

Regs say "to protect the pipe from structural movement". Which is "from movement in the wall".
Not protecton of the pipe from movement within the wall.
Your original reply missed the important detail of not filling completely around the pipe. @sacredhart was correct in calling it.
The gas pipe has an end feed elbow extending into the sleeve, so whilst it's unlikely, it's still possibly a leak source now or in the future besides the pipe itself aging. If the proposed seal up is better sealed than the inside of the property, any gas will leak inside.
Unlikely a fire risk, as you need a decent flow of gas for a flame. But a slight leak build up can cause a house leveling explosion -

No, pipe clips do that.
let’s talk real life her instead of theoreticals
Gas regs are reactive not proactive generally so there will have been real life incidents investigated which resulted in these regs.
You can disagree all you want
It's the regs and therefore the law that disagrees with you.
but even if he sealed it what’s it gonna do?(sic)
Potentially leak gas back into the building causing an explosion/ death.

Not sure why you have used quotes you are either qualified or you aren't. Dont work wih those engineers then. And don't use them as your benchmark I would suggest.
wouldn’t be worrying about triviality like this.
This is a worrying statement given the points raised so far. The regs are law and to primarily protect life.
You are an example of the worst type of tradesperson. You don't know you limits, have no respect for the rules, law or the safety of your customers. And you are judging yourself against the worst work you see. Stay away from gas and leave it to the pros.

I completely disagree. With gas you don't want to rely on common sense or interpretation. You want clearly written rules.
You first answer was wrong as you advised a DIYer to seal the pipe with silicone, ommiting to mention the important part about venting to outside. This is particularly relevant in the above photo as the sleeve does not extend beyond the face of the wall so a DIY attempt to seal based on your initial advice would certainly seal the sleeve.
You are also wrong the sleeve is just there to prevent gas escape into a void. If you were familiar with / had read the regs you posted above you will note the sleeve is also there to protect the pipework from movement in the wall.
