What does the bulkhead need to be made of? I can find no reference to it in the IVA. Of course I want one, but do I need to use 5mm steel plate or
tissues paper?! 
Of course, I want it to be safe, and will make it so, but what is the legal perspective?
EDIT: My engine is behind the driver, if that makes a difference, and of course the driver will still need protection from the elements up front.

I think most people fit an aluminium bulkhead rather than steel even though steel has a much higher melting point which would be an advantage in the
event of an engine fire.
On my trials car which is mid-engined, I am using 16gauge (1.5mm) pure aluminium grade 1050A. 18 gauge (1.2mm) NS4 aluminium would probably have been
better in resect of strength and stiffness but in my case, I needed to do a bit of forming and shaping so I took the easy way out!
I don't think there is a definitive answer and in the end, it's a question of personal choice.

I'd second aluminium as the choice for bulkhead material, much more workable than steel (or tissue paper come to that!).
