Any reason why these can't be laid straight onto the existing

How sure are you it is flooring grade chipboard?

There's a layer of lino on it and a layer of cork tiles on top of that
so I don't know what the surface looks like yet.

You do not . as such need
to retain the chipboard as this will cause a step (the tiles will anyway
unless you plane down the joists).

I'm not sure I understand this. The rest of the flat has 14mm
hardwood flooring on top of underlay on top of the chipboard (at least
outside the bathroom) so there will be a step at the bathroom door of
some kind anyway.

will probably be useful.

Thanks, I've bookmarked it.
