I hope those tails are double insulated as single insulated conductors are not permitted to be used for meter tail applications. Also there should have been a fused isolator used for the isolation of the armoured cables as otherwise the suppliers fuse is protecting the whole length of the cable including the SWA to the apartments. The armoured cables glanded into the trunking do look very sloppy also not that because they are glanded into the same metallic enclosure they will now be sharing an earth connection. I susopect there will be some sort of through crimp in the trunking joing the meter tails to the armoured cores, and this is not ideal either.
All in all a very sloppy installation.
