So based in the UK, doing a full-house renovation at a typical Victorian semi-detach. UK fire regulation means we need to build this firewall along the staircase. question is how do I finish the plasterboard bordering with the staircase as I assume they will crack from day 1?

Do I put end beads along the edge (and how?), or use skirting boards?

Any tips please!

Thanks!

I somehow doubt that your wall meets the definition of a fire resistant wall (all such walls I've built in recent years called for double boarding both sides, mostly onto metal studwork, but I have to admit I've just worked to the S/Es spec), however you might want to consider packing mineral wool batting into the voids in the frame - if nothing else, done properly (i.e a very snug fit), it will improve sound and heat insulation to a degree. Cut the plaster boards as tight as you can with as few joints as possible and caulk any gaps at the bottoms and tops of boards with an acrylic intumescent caulk.

Yes will definitely stuff it with insulation. Should I do a stop bead to the bottom end of plasterboards still?
 
I don't think I'd bother, especially if you i tend to run a skirting up the wall, unless the boarding overhangs the stringer. I do think it is more important to firestop any gaps than add the stop bead, though
