A service riser can be a protected shaft and open at each floor with no horizontal seal, but the vertical walls (& doors/hatches in them) should be complete and of the correct fire resistance.
Missing/incomplete inner plasterboard layers to walls of riser shafts is a not uncommon defect in modern builds, usually corner cutting where no one will see.
