Cavity wall insulation for landlords for Penzance properties

Penzance is among the towns we cover in Cornwall, alongside Camborne, Redruth and Falmouth. It is roughly 24 miles south-west of Truro.

For landlords and managing agents in Penzance, we survey in batches and return a result sheet and fixed price per address. Blocks of flats in Penzance are surveyed as a whole, because the cavity runs across every flat in the building.

Wind-driven rain is the first thing the surveyor weighs up. 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 Penzance 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.
