Exposure matters for every cavity wall. Much of Greater London 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.

For regulations, if cavity wall insulation follows in Woodford Green, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
