So this is an IKEA kitchen. They organised the fitter who then organised the supplemental works (electrics ect). I can't comment on the suitability of the rails/ how well they are secured but a quick check online does look like they are mounted the correct way up at least.
The fridge, freezer and oven are all the othe side out of shot of the image. It the far corner there is a second double socket (behind the ladder you can see where the back box will go) and there is another of the other side of the window.
There is a plan, there is a full 3d model of the kitchen which was done with IKEA which focused on organising and then when the fitter come out pre installation we went through the additional thinks that would also need changing (moving some of the sockets because they were close to sinks ect.) admittedly the isolation switch location wasn't discussed though.
