Or, more accurately, if the pile of soggy chipboard (which a previous
householder dumped at the bottom of the garden) is put under cover, will
it eventually dry out sufficiently to make a bonfire, like normal timber
wood do, or is it not worth trying - shall I just hire the skip?

My feeling is the stuff is so waterlogged (2-3 time it's normal weight!)
the water will never come out (especially the melamine coated stuff).
Anyone tried it ;-)
