Work on Truro rented homes and blocks is booked around tenants and residents, with access arranged through your agent if you prefer. Blocks of flats in Truro are surveyed as a whole, because the cavity runs across every flat in the building.

Exposure matters for every cavity wall. Parts of Cornwall face some of the heaviest wind-driven rain in the UK, especially exposed coastal and upland sites. Here the survey is stricter: some walls suit only certain certified systems, and some should not be filled at all.

On the rules side, in Truro 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.
