randomly hit the keyboard and produced:

Which builder was it that put a house up with a wall so thin it moved if hit
with a screwdriver? It wouldn't pass a building inspection in the condition
you describe.

The only Building Regulations requirement for a non-loadbearing wall
is airborne sound insulation. One layer of 12mm p/bd each side and
25mm mineral fibre between the studs will suffice. The studs may be
75mm timber or 45mm metal. There's no requirements for robustness or
impact resistance.
