You do need a registered qualified fitter for any LV’s rather than a run of the mill domestic carpet fitter that will only glue around the edges as you would fit standard vinyl, hence cause issues you have mentioned after fitment.
I got mine as large offcuts when I working as a spark on new 4star ibis hotels and the guys fitted it for me. In my opinion hotels would use it if it was crap and a safety hazard.
