That sounds more like a ladder than a staircase! To meet building regs
the maximum inclination of the stair should be 42 degrees. Max rise per
step of 220mm and minimum going per tread of 220mm. Note that you can't
have the max rise and min going in use at the same time.

Look at Part K. Note that the rules can be relaxed in some cases for
loft conversions.

The space of the mezzanine itself fits in a lowered loft space, and will be
approx ~6' high at the apex going down to ~3' at the eaves.
Are there any regulations as to space requirements? Use is occasional
bedroom.

Don't think there is a minimum height requirement for the room itself.
There is one for the headroom over a staircase though. (at least 1.9m in
the centre of the treads)

I was hopeing to put a velux in the roof, but am unsure how planning
permission may be affected by this, it can go on either aspect, but the

As long as you are not in a conservation area or own a listed building
then PP is highly unlikely to be required for a velux - even if facing
the highway.
