Depends on the colour code chosen and the application I guess.
Here we see 4 screw terminals and 3 pins to the plug and socket pair.
If this is supposed to replace a celing rose with power loop in and out and the switch on the leftmost T& E, then no, as the have the switch in parallel with the lamp If the left most T& E is supply to the lamp, and the others are just looping through and share a neutral , then maybe,
IMO, that picture shows what appears to be the switch line connected via Neutral to switch, should be Live to switch, and for the sake of clarity, be colour reversed with a brown id on the blue conductor ....
I say no because the neutral is being switched and without seeing the connection to the lamp plug the lamp appears to be connected to a permanent neutral and a switched neutral.
Or or worse still if you can switch the lamp on and off the lamp connection is reverse polarity and has a switched neutral.
On face value the wiring is fine unless you know that twin goes to a switch by itself. So the missing cord grip is the only thing that is not right, subject to confirming the t + e is not your usual " switch wire".
It's not far out. Presumably we have loop in and loop out; switch drop; and connection to luminaire. It appears that the luminaire is connected to the three terminals on the left, (left to right) they are SL, CPC, N. That leaves the terminal on the far right which is L. The blue conductor of the left hand cable needs to be connected to the far right terminal and have some brown sleeving.
I assume that the cords are gripped when the two halves of the shell are put together.
(I would prefer that all three browns were together and blue sleeved brown was the SL on the far left.)
