I found an article but noticed the wiring looking a bit dodgy how it is run.
https://www.bbc.co.uk/news/uk-england-london-60364090Hackney Wick: Collapse of bar floor injures 13
Notice: Two cable wall clips on the left, and only one clip on the right.
As pointed out by Dunkemhigh and on closer look not the same length with the right smaller than the left.I can barely see what looks like a gland between the light switches
ontop underneath joining onto the socket to the left under it.
The wire seems to be curved near the support is and a bit stretched onto the socket near the window.
The picture is bit unclear but near the window is that look like thick stranded core cable that's used behind walls?
I have seen the sockets like that many times before wired externally where the cables are in pipes, a few very with thick plastic looking cables with a plastic cover that covers of the glands on the socket and a few in trunking.
What do you see? Is it just untidy or dodgy/poorly laid out?
