Cavity wall insulation for flats for Bognor Regis properties
If your property is in Bognor Regis or the PO21 district or nearby Chichester, Littlehampton and Worthing, it is within our West Sussex coverage. It is around 32 miles south-west of Crawley.
Blocks of flats in Bognor Regis are surveyed as a whole, because the cavity runs across every flat in the building. For commercial buildings in Bognor Regis, the survey also considers building use and fire requirements before a material is specified.
Local weather affects which walls can be filled. West Sussex 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.
In terms of approvals, in Bognor Regis 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.
