Hi i wonder if anyone can advise please….
Old victorian house…knocked a wall down to open up the space….floor fitter laid a 9mm plu and then screeded the floor…laid the lvt…and there is an incline…u can feel the floor go down and then back up…he told me its because the house is old and ineven and thats what causes it…i asked well does the ply and screed not fix that issue…he said no he applied for the levelling point (whatever that means)????….is tgis correct as he never mentioned it wouldnt all be level…am really not happy but it has all been laid now

The issue sounds like a dip under the ply that perhaps should have been addressed before laying the ply. The problem you face is that the floor will have to come up to fix it unless (if you have suspended wooden floors) you have a crawl space under the floor which would allow you space to put some shims under to reinforce the dip.

As dwd says the problem lies under the ply. I've done the same sort of thing in old properties , fitting firrings on top of bowed or sagged joists. Days spent with strips of wood , a line and a power planer. Horrible job to be honest. If the floor just dips in the centre it might be alleviated a bit with self levelling compound or you could just live with the idea of it being the "character" of an old building. One job we did where we levelled the floor and then put down oak flooring that had to be completely free of faults just looked "wrong" in an 18-19 century building.

depends what the op means here i would say. does the floor move down and up ie bounce? or does the floor have a slight dip that then raises upagain on the other side?

sometimes when using smoothing compounds (everyone says leveling compounds) you can find that it still kind of follows the shape of the original flooring somewhat. like you can put a real long straight edge and there weill still be high points and low points. you could spend some major money on compounds to get over it in some cases
