As for paperwork, in Plymstock filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

Why one flat cannot usually be done alone

The cavity runs continuously across the building. The Energy Saving Trust notes that flats need agreement from the whole block. Filling one flat's walls in isolation leaves gaps, and the freeholder normally owns the structure.
