What installation method is this - which one of these electricians is wrong ?

[Scalar6]

Hi

My company recently required an electrician to install a new 32A 400V socket in our workshop. The guy who did the job, installed 32A, 3-pole circuit braker, type C and 2.5mm SWA cable, as he was confident to use the installation method reference 'E' in his calculations. The thing is, that the cable is cliped on to the wall and then laid on the top of the wall together with other cabels (please see pictures). Previous electricians, who did other work 2 months ago in our workshop, installed a similar 32A 400V socket, and used SWA 4mm cable and reference method 'C'. Lengths of cables are almost identical, as both sockets are installed close to each other and go to one the same distribution board. My question is: which one of them is wrong ? Really don't know where I can go to ask the question and get some opinions - that's why I posted here... Thank you for any valuable answer.

Its definitely not reference method E as that is tray/ladder install. Reference method C is clipped direct

As above, ref C. Im guessing your electrician that said E couldn't be bothered to look in the regs

Any reason why you did not use the same spark to install the second socket outlet?
