I was questioning myself as I wrote it. I have done it before but didn't think it was allowed. Maybe someone else can confirm. Further searching reveals it's muddy waters.
The underfloor route would often be preferred as corners tend to have a bit more going on structurally but that depends on the age and construction and I think you're in a new build?
I see now why you are thinking trunking would ensure the wires stay on the horizontal. In my experience trunking is not often used in walls. There's a type of capping which is useful in solid walls if you are plastering over the chase.
I just had a real electrician (tm) do some corners for me. Chased into plaster walls. He isn’t the type to fuck about with noncompliance - he suggested corners as a good spot to spur through from other rooms if necessary, and mentioned safe zones exactly as described above.
