SWMBO insists that we get laminate in the living room.

Planning on using the fibreboard-y underlay as there a few areas with a
1-2mm difference in level and an old concrete hearth. Under the
existing floor there's about 500mm gap down to an earth solum, so will
I need any sort of damp/vapour barrier under the underlay?

Always use a DPM when laid on a concrete ground floor ... personally I use a
3mm closed cell underlay with a built in DPM (UniClic product), if you
don't want to use that then lay a polythene sheet down first ... you can buy
this in small packs in B&Q or builders merchants or in large rolls .... buy
the thin clear polythene sheet, not the thick black DPM.
