I have boarded out my laundry room with celotex, do I have to board over it or can I just leave it

If you have sealed and foiled it, that is all you need to do from the
insulating point of view, but seriously, you want a tinfoil coloured room?

So long as its vapour tight (i.e. foil faces, ali tape on all the joins
etc), then you don't need to do more. However it is rather vulnerable to
damage like that, so a skin of ply or plasterboard would help protect it
and leave you a surface that could be decorated.

I wouldn't. You should overlay it with plasterboard, or if money
is no option, Fermacell.
The former ought to be skimmed because it is a wet room. The
latter can be sealed with their proprietory smooth-finish
stuff that is ready-mixed, painted on, squeegeed off and
fine-sanded when dry.

Great, that would be amazing man....

If it catches fire, it releases cyanide. Plasterboard it.

Incidentally, some tumble dryers catch fire when they get full of lint.
Our Miele one switched itself off and displayed an error code saying
what the problem was.

Celotex will not catch fire until it is exposed to temperatures
much higher than a domestic fire. It will char and pong a bit
(hopefully) but that's it. Still a bad idea to leave it
unprotected though.

expanded and extruded polystyrene is a different animal, this
really will burn furiously and give off lots of deadly smoke.
