Laminate flooring (Totterdown BS4)

I have some laminate flooring I've recently removed from a room that is about 4m x 5m. See photo for the make and type. It's in used condition - has been down for several years and most of the pieces have scratches on them, some more than others. The individual pieces are about 129cm x 20cm, some are smaller than this as they've been cut to fit the room. I also have the underlay, which is made of a cardboard-like material.
