Before any material is chosen, exposure is checked. 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.

On the rules side, if cavity wall insulation follows in Heston, filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

Why refill at all?

Often the original problem was the wrong material for the exposure, poor installation or defects in the outer wall, not cavity insulation as such. Once the defects are fixed and the cavity is clean, a suitable certified system can usually go back in. Where the wall is too exposed for any fill, we say so and leave it empty.
