Some of the workmanship speaks for itself. I guess they couldn't put a cover on that box on the tree if they wanted to, what with the cable not even entering through a hole!
I assume this was meant to be wired to British standards from the red/yellow/blue/black wires, but it seems they've used black as a phase. I wonder if the blue or the yellow is the neutral?
Last pic looks as if the dreaded plasterer has struck again!
