I’m not the fitter but the actual fitters have been clear that they more or less drop the kitchen and subject to a few bits of adjustments here and there then that the extent of what they’ll do.
I’m hoping it includes taking into consideration the floor situation.
This would be what I’d expect too. Legs should be adjustable, so the ones at the front can be a bit shorter than ones at the back to allow for level change.
Ah don’t worry they’ll have to take the floor into account and level off the units etc. Should be no issue.
They only say about doing nothing extra so people don’t be trying to get them to hang a few doors while they are at it.
