Cavity wall insulation for landlords for Worthing properties

Worthing sits in West Sussex, around 22 miles south of Crawley. We work across the BN11 district, including nearby Littlehampton, Bognor Regis and Burgess Hill.

Per-address photo records for Worthing properties make compliance files and EPC updates straightforward. For landlords and managing agents in Worthing, we survey in batches and return a result sheet and fixed price per address.

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.

As for paperwork, in Worthing 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.

Planning for EPC C

Government has confirmed that private rented homes in England will need to reach EPC band C by October 2030, with a £10,000 cost cap and exemptions. A filled cavity often contributes a meaningful share of the points needed, and it can be done with tenants in place because the work is outside.
