Blown mineral wool insulation 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.
Most Bognor Regis houses built from the 1920s onwards have cavity walls, but the survey still checks each one: cavity width, debris, the condition of the brickwork and how exposed each wall is. Where a Bognor Regis property has an extension or a conservatory, we check how the old and new walls meet, because that junction is often missed.
Exposure matters for every cavity wall. 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.
On the rules side, in Bognor Regis filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.
Funding in England

When is it not the right choice?
Very narrow or uneven cavities, walls with lots of mortar snots and debris, and some very exposed elevations can be better suited to bonded bead, which flows around obstructions and is certified for a wider range of exposure zones in some systems. The survey says which and why.
