Cavity wall insulation for flats in Greenford

For homes and buildings in Greenford, cavity wall insulation for flats is arranged survey-first: we check the property, tell you plainly what we found, and price it. Flats share their outer walls, so cavity wall insulation is normally done for the whole block at once with the freeholder's agreement.

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.

In terms of approvals, in Greenford filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

Funding in England

In England, ECO4 runs to 31 December 2026 and Warm Homes: Local Grant supports low-income households through councils.

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.
