I've rented.....8 houses so far, all in North East(Newcastle) and every single one of them had a dishwasher. I suppose maybe part of it is that I simply wouldn't rent a place without a dishwasher ;-)
Well in a lot of places, the fact it is a self standing property means the owner can do whatever they want with it without having to consult a "building committee".
Like rearranging plumbing/electrical however you want.
Whether landlords use this advantage for tenants quality of life is a whole other story.
I've rented flats outside london for years, always come with a dishwasher. I'm on a high salary though, so it may skew my world view of what is "standard"
