You will be bringing the floor up so high, could you not get electric ufh

This is'nt going to work with that amount of bounce with the tiles laid, they will crack with that movement

What area of London is that mate

 

[jay]

from the sounds of what you have told us you might have a problem which you are not aware of

 

[jay]

the ufh needs to be screeded to protect pipes then floor coverings applied over (after the correct drying time and commissioning of floor heating )

the way you have described it there is every chance that the pipes will get damaged from constant abrasion from ply causing the pipes to rupture and leak causing a lot of damage
i recommend you ask for someone to have a look at what has been done as i think you are sitting on a time bomb
prob not the answer you were looking for but its a concern hope this helps

Jay my pipes are going in a metal plates (like on the picture from part 6- Suspended wood floor) but underneth I have concrete floor, no joist. Do you think that ply can be screwed to the concrete through that metal plate? Will metal plate protect those pipes? And how thick should ply be?

how do you support the metal plates as there designed for timber
yes pipes are protected
i recomend screeding pipes in then theres no chance of any movement
and the manufacture does to if you could fasten with no movement at all no bounce then you would need to go up to a min of 18mm ply but i think screeding would be cheaper hope this helps
