Exposure matters for every cavity wall. Much of Surrey sits in the more sheltered driving-rain zones of the UK, which widens the choice of fill. Exposed elevations, coastal sites and high ground still get checked wall by wall.

On compliance, in Redhill 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.
