Cavity wall insulation for flats for Littlehampton properties

Our West Sussex coverage takes in Littlehampton (BN17) and nearby Bognor Regis, Worthing and Chichester. It is around 26 miles south-west of Crawley.

Work on Littlehampton rented homes and blocks is booked around tenants and residents, with access arranged through your agent if you prefer. For landlords and managing agents in Littlehampton, we survey in batches and return a result sheet and fixed price per address.

Before any material is chosen, exposure is checked. 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.

For regulations, in Littlehampton 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.

Fire and height

For blocks, the material must suit the building's height and use. Non-combustible mineral wool is the usual choice; we confirm the system and its certificate limits in writing.
