if your customer wont take out the fittings and it has to stay down i would make sure you state that you cant guarentee the work, regs state 15mm ply on floorboards and the boards have to be screwed to the joists, (i will only use 12mm at min and only if the floorboards are in really good nick) if you cant say this has been done i would make sure they are aware first.
