Hello. Got a bit of sticky situation here.
Got called to check on burning smell and arcing from electricity cupboard. Some power loss been reported too.
Its a first floor flat and the power is coming from cutout downstairs (a very, very old cable looking like a VIR and disapperaring behind the board)
Found some charring on the neutral, i suspect that there will be a loose connection inside one of those metal casings.
But i`m not really up for working on it live.

Downstairs flat is owned by different people, we managed to access it and tried to isolate the supply to upstairs, but found that:

There is one service head, one 100A fuse that feeds the meter - for downstairs flat.
Then is the red cable on the left, is leaving the cutout from the side (not from any of the remaining fuses, unless there is some connection inside the cutout?), goes into henley block and splits into dodgy vir cable for flat upstairs, and dodgy vir cable powering flat next door.
If it was one fuse per flat i could call the fairies and sort it out quickly, but thats a bit too much for me.
Informed the customer that there is no way to safely isolate and he should get the UK power network or electrity supplier to sort it out.
He called both but they refuse doing the job.
Not sure what to do now. Advised the guy to write a recorded paper letter and ask for reply on the paper too, in case something goes in flames before.
