Hi BigWallop,
Yep - but not the space saver style - this model...
http://www.the-wooden-hill-company.co.uk/kompact/kompact_modular_staircase.htm
I just got a post this evening from Bill Howe who sells the stairs in
the UK giving the following information:
The weight of a 14 riser Kompact 89 is listed as 288kgs., if you are
thinking of putting an outside handrail on it would add extra weight,
so I would suggest 300kgs would be a nice round figure to work on.
so, am I close to understanding what specification the beam should be?
I've just had a nasty shock and realised I have to pay even more for
my building control fee than I though because the loft room will be
over 10m2 floor area. It works out at 150 ish for plan fee and 350 ish
for inspection fees. This makes it even less likely that I can afford
a structural engineers report!

The weight should be evenly distributed over the bottom floor and the intermediate
supports that you set in between the full height of the rise, so the weight issue is
only a major factor if you are setting the staircase onto a soft or flexible floor
structure. The top of the staircase is only resting against the top landing and, as
said before, as long as you know the top landing can support the weight of a few
people standing on it, them it should be able to take the weight of the top few treads
of the staircase resting on it.
The .PDF file links at the bottom of the website you link to show a great example of
how these stairs go together. You'll also have to check with your local authority
that these designs of staircases are allowed under their fire escape regulations if
the installation is for a habitable loft conversion.
