I thought it was my eyes with the labelling on the consumer unit.Unfortunately as you are finding, there is little to no practical oversight of the PRS scheme. It is the local authority who has the official oversight, rather than NAPIT, though they might have done more to address your concerns IMO.
Depending on your council, they may or may not be helpful - some of them have rental standards which they require every landlord to meet, others don't. Based on the finish around the socket, it may be that there are others non electrical issues that are also not up to standard? (Is that mould to the right hand wall?)
The pictures themselves don't look quite as dangerous as you think, though certainly the cables not being correctly clipped to the wall should have been noted on the EICR. Being exposed is not in itself an issue, if they are suitably secured.
If you can put a redacted copy of the EICR up, then it may be clearer whether it was a poorly done report, or something more obviously nefarious.
On a final note, based on the labels on the consumer unit, someone needs to buy that electrician a spirit level!
Poor things like that do get alarm bells ringing however I don’t think that means that the electrician is a fraud. The cables not secured don’t present immediate danger but need to be securely fixed I’m on the borderline of C2/C3 on this one due to the potential of cable being pulled easily and causing harm.
Hope you get issues resolved quickly keep us posted
