Can anyone tell me if a stud partition wall, timber with 12.5mm plasterboard either side, built to separate the area above offices/stores from a workshop, meets fire safety regulations as it is or does it need to be clad/finished before it meets regulations. I believe the plasterboard itself is 30 min fire resistant.

Thanks in advance

Normally a stud wall with 12.5mm plasterboard either side, if correctly built and fitted would achieve 30 minutes. Usually edges needs to be taped and sealed or a plaster skim applied as well
