[Closed] Electricians - does this look right in our kitchen?

So were checking around our new kitchen and finding lots of problems and shoddy work, we're dealing with it at the moment, but also saw this the other day which is under the sink unit, pretty sure this shouldn't be left like this? Would appreciate some advice on what should be done, should this be boxed in or sealed up in some way? Just doesn't look good or right to me. I've googled it but can't really find anything that refers to something like this, ended up looking at lots of regulations etc but nothing specific and this place has been great for getting answers quickly and advice. Thanks.

Also, if this is insuffient who can I contact about this, Trading Standards seem to be a waste of time as you can't even contact them directly anymore, you have to go through some citizens advice service and they pass it on, I've already complained about the kitchen fitters but as far as I know nothing will get done. The electrician who did this is supposed to be issuing us with an installation certificate ... 😐
