He damaged the extractor fan when putting it up because he forced it when he couldn't get the clips to line up, the housing is chewed up and the bearing is out, so the whole thing vibrates. He also wired the earth into the switched live terminal for the boost (it's marked T so maybe he thought Terre? No clue).

He left about 1m slack on the flex running from the built-in cooker hood to the isolator, and fed that cable through the 150mm hole cut in the top box for the ducting instead of the hole drilled in the back corner for the cable. Not a massive deal, will take a few minutes to redo but I shouldn't have to.

He unilaterally decided to change a socket position from down the side of the fridge to in a wall cabinet. We explained to him well in advance that there would be a ~100mm gap that might be hard to work in, so maybe do that that socket on the first fix. We also then said we could pull the fridge cabinet out to give him space to work when he came back (we left it attached with only 2 screws because we were pretty sure it was going to need to come out). Apparently his solution was to move a socket meant for a vacuum cleaner into a cupboard at eye height.

And just in general, everything is wonky. Extractor fan, every isolator, almost every socket. Only by a little bit but it's just sloppy.
Sounds like you could have accomplished it yourself.

It’s good that you know when it’s not right.

And you also know how bad some sparks are, although maybe compliant the work is just a mess

It’s sometimes very difficult to do a job that you are 100% happy with there is always something.

You usually find that not taking your time and thinking about about stuff ends up taking more time and effort.

Changing a class II to class I is bad enough, but to not attempt to earth the fitting is diabolical.

I’d expect some sort of Heath Robinson… a bit of earth wire with a ring crimp on the end, with the fixing screw tightened up would effectively earth the fitting ( if the main body was then screwed to the bracket)
But he hasn’t even done that.
I find with these so called 'class 2' metal light fittings which are basically class 1 fittings with a crappy supposedly double insulated joint box supplied to be a total waste of time, if a typical loop in wiring method is present(which it mostly is) the only way to install the light safely is indeed to ring crimp the CPCs and screw them to the fixing screw of the base bracket, like you said, which at least provides an earthed light fitting

This is my method when dealing with these fittings and sadly the only choice I can think of.

unless you have a single cable entering the light fitting it is impossible to ensure a class 2 double insulated situation is maintained, they are a terrible design and lead mainly to an unearthed class 1 fitting as in the post
