If that is an IET link it won't work here. Show where that Regulation infers what you suggest.

You've appear to have copied & paste some lines in your reply. If you could citations. Edit IET.The intent of Regulation 421.1.201 is considered to be, as far as is reasonably practicable, to contain any fire within the enclosure or cabinet and to minimise the escape of flames.
It is important for the installer to seal all openings into the enclosure or cabinet for cables, conduits, trunking or ducting that remain after the installation of cables - see Figure 6. The intent of the sealing is to ensure that, as far as is reasonably practicable, any fire is contained within the enclosure or cabinet and the escape of flames to the surroundings of the cabinet or enclosure or into conduits trunking or ducting is minimised, as intended by Regulation 421.1.201.
Good workmanship and proper materials must be used, and account must be taken of the manufacturer’s relevant instructions if any.
Metal box, with restricted air inlet, opening into a vertical cavity is a definition of both the CU in the OP, and the wood burner beside me, that my wife has just lit.

I'm no longer up to date on BS7671, so I'll tilt my hat to you.
If you going to spend time and money 'to seal all openings', what are you going to do with the big flap on the front of a consumer unit, that covers all the inner workings of said CU? Seems little pointless 'sealing' everything, when this is flawed by the CU cover?
The debate is over whether to leave an oversized hole in the rear of a CU that goes into a wooden partition.
No one intends to light a fire in a DB, but we all know that they manage to do this themselves, usually when one of the poorly designed connections isn't assembled properly.DBs aren't intended for lighting fires in.
The same argument could be applied to kitchens fitted with an extractor fan and trickle window vent and the likelihood of fires starting in a kitchen are considerably higher, than one starting in a DB installed in line with regulatory requirements.

Don't think a wall mounted extractor in a kitchen is going to fan a kitchen fire to any significant degree, and there's a minimum distance between a hob and and extractor over it for just that reason.
You stated in post #11 that this involved a partition.
The reality is that it's a studio set and we don't know what they intended it to represent. I'm going with the previous suggestion of it representing a board spaced off a wall with battens, because I like that idea.
