that work is terrible.
It would be interesting to see a pic or two of the insides of some of the wired switches/sockets, just to see if it shows any more shoddy details, but agree with other posters here that the OP perhaps should be cautious about how much is said or shown here until after the legals have finished.
Missed it when i first looked, but the door-socket is a work of art
OP, when this guy turned up in the mornings, did you notice anything odd about him? (like a carrier bag stuck to his face and a overwhelming smell of glue?)
