Had a moment after hanging the fridge (next to the kitchen window), wife comes in and says the fridge isn't vertical. I've measured the mounting rail prior to hanging and the fridge itself after mounting and assure her it is. Only to find that of course, the window itself isn't completely straight. We've got a long kitchen with 2 roughly equal sized worktops going down either end. The floor isn't completely flat so where the worktops reach the end (again, with some excellently placed windows to show the unevenness), one is pretty much bang on the window sill, one a few cm below.
No intentions to fit the kitchen wonkily to offset the inherent wonkiness of the house (this may be where professional fitters are beneficial mind you).
We installed an IKEA kitchen in our place in the summer there, my father-in-law, my wife & I. Took a few days to get the old one out and the new one in and it was all pretty painless. No experience of getting people in to fit one, but everyone I talked to said that it took a fair bit longer than what we'd done. And that was including having a toddler walking around asking what all the bits were for.
I'm guessing IKEA kitchens aren't everyone's cup of tea, but in terms of installing them, I'd wager it's as easy as it gets.
Also saves on playing builder-roulette.
Edit: Also, IKEA have a pretty decent kitchen designer program to help plan everything out which was super useful.
