Cavity wall insulation for Bognor Regis properties
Bognor Regis sits in West Sussex, around 32 miles south-west of Crawley. We work across the PO21 district, including nearby Chichester, Littlehampton and Worthing.
For semi-detached and terraced homes in Bognor Regis, cavity barriers are fitted where your wall meets your neighbour's so the fill stays on your side. 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.
Every elevation is judged on its own exposure. 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 compliance, in Bognor Regis filling a cavity is notifiable building work and needs a building notice or competent-person self-certification.

Is my wall suitable for cavity wall insulation?
Most homes built from the 1920s onwards have cavity walls, but having a cavity is not the same as being suitable. The Energy Saving Trust's rule of thumb is a cavity of at least 50mm, clear of rubble, behind masonry in good condition, on a wall that is not exposed to severe driving rain or flood risk.
