A POST FOR DISCUSSION

An EICR in my rented flat concluded that an RCD was required among a few other small jobs. I was away while the remedials were carried out but these photo are of the work which was done.

The double pole main isolator was removed and replaced with the 80A RCD and among other problems with the jobs they did, the neutral from the RCD had never been tightened up so they did no testing either.

There's a few things in the photo that jump out to me but I'd just like to hear your thoughts on what they've done.

As above. That RCD doesn't fit. The RCD is being twisted up and the MCBs are being twisted down, and the cover will not fit on properly.
Why on earth didn't they scratch off the printed L and N at the top of the RCD and connect it with neaureal on the left and live o the right. Three must be a VERY tight clearance where the busbar passes the neutral at the bottom, fused only by the DNO cut out.

It’s not a good job, have you received an installation certificate?

It's not a good job at all. Even if a correctly fitting RCD had been sourced and fitted, it's still very poor practice to have the whole flat on a single RCD. A neutral -earth fault will leave the tenant with no electricity at all.
I'm intrigued as to why? There's plenty of examples on here of CU's being condemned and replaced unnecessarily, but with this one, there are reasons for a replacement, but the electrician has chosen to bodge. This is the kind of solution I'd expect from a DIYer, trying to save their cash.

Such a shame the plumber butchered that board by fitting a wylex rcd and snapping off the left lid screw.
the original board with the original main switch was a nice job who ever first installed it
