I've just bought 20 packs (31.5m2) of QuickStep Laminate from builders depot.
It comes with free underlay but I'm happy to spend a bit more for a quieter and warmer floor.
It's to be laid on a new build ground floor concrete floor.
Urgent thoughts please?

Go with unisound or silent walk if getting Quickstep underlay
Or duralay Timbermate Excel
 
New build floor will already be really well insulated. If you want it to be warm you either need ufh or carpet.
For sound, it's hard to do much unless you want to go for vinyl floor rather than laminate.
For damp the floor should have a DPM properly laid and sealed in a new build, so no need for damp proof underlay.

Thanks John, using an underlay that is also a DPM was suggested to be a good idea because of any residual moisture in the poured concrete rather than moisture from the ground.
 
You need to make sure the concrete is fully dry before laying any flooring. Put a plastic sheet down for a couple of days and check for condensation. If there's non underneath, it's dry

I don't have a choice sadly - we're due to move in and "she" won't do that without the flooring down.
 
you living with lord voldermort or something? You don't want to be trapping moisture anywhere in your house, but I suppose if you do it anywhere, a screed floor isn't the worse place. Use the non waterproof (breathable) underlay and at least it will be able to evaporate in the long term.
 
Or put down a moisture suppressant like

Ardex MVS
Fball F78
Uzin PE404
Laybond rapid dpm

All above you roll on 2 coats
