Cavity wall insulation for flats for Tewkesbury properties
We cover Tewkesbury and the GL20 postcode district, including nearby Cheltenham, Gloucester and Stroud. It is roughly 9 miles north of Gloucester.
Blocks of flats in Tewkesbury are surveyed as a whole, because the cavity runs across every flat in the building. For commercial buildings in Tewkesbury, the survey also considers building use and fire requirements before a material is specified.
Every elevation is judged on its own exposure. Gloucestershire has a mix of moderate and more exposed sites. Hilltop, coastal and west-facing walls take the brunt of wind-driven rain, so the survey records exposure for each elevation before a material is chosen.
For regulations, in Tewkesbury filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
Funding in England

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.
