Hello all, just a quick one, what do you lot recom3nd as the cheapest method of keeping floor levels throughout the whole of a down stairs if only the kitchen is having electric ufh. Its over screed and chipboard (which I will be ripping up and replacing with a better substrate). 6mm tile backer board and either dcm, or vairo pro down. But I will need to hold the levels through another 35m2. Any suggestions on how to achieve this in a cost effective t manner ?
