Okay if it was the for ever house I'd not get anything made of chipboard full stop.
It doesn't last, I just took out our old Magnet kitchen, high quality in 1984, not reduced to a mouldy, rusting, ill fitting monstrosity that was unfixable and uncleanable.
I've fitted solid wood and a soild wood worktop, ceramic sink and ceramic floor tiles. I know that this stuff will last and if it does ever want fixing or bits replacing it won't be unworkable. You can always work with wood.
I'd consider a vinyl floor but only a very decent one, otherwise it would be tiles I'm afraid and make sure they are the sort that clean easily.
You are probably onto a saving using ceramic tiles sourced cheaply (ebay job lot, or discount warehouse etc) than a decent quality vinyl for that square meterage.
Just my thoughts, yes it will be pricey but it'll last, you'll only be ripping out something cheap in a few years so it'll be a false economy iyswim.
Our tiles cost £74 (plus cement, grout etc), as they were end of line - that's 11 square metres so times by four and it's far less than good vinyl I reckon. Second hand sink from kitchen fitter, so barely used and a tiny chip, v reasonable from ebay. Worktop also from large company on ebay, really about a third of full price in B&Q or somewhere. Four metres for about £150.
If you shop about, it can be done so cheaply. Take your time, get the cooker and sink done, plus floors and walls and then you have your blank canvas to add to gradually. that's just the way I'd do it - if you want it all finished quickly, you'll spend more! I have some freestanding bits in the meantime. It's brilliant.
