Commercial cavity wall insulation for Exeter properties
Our Devon coverage takes in Exeter (EX4) and nearby Exmouth, Tiverton and Newton Abbot. Exeter is one of the main towns we cover in Devon.
Blocks of flats in Exeter are surveyed as a whole, because the cavity runs across every flat in the building. Work on Exeter rented homes and blocks is booked around tenants and residents, with access arranged through your agent if you prefer.
Wind-driven rain is the first thing the surveyor weighs up. Parts of Devon 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.
In terms of approvals, in Exeter 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.

What is different on commercial jobs
Access is planned around opening hours, often with towers or MEWPs. Material choice takes account of building use and fire requirements, so non-combustible mineral wool is often specified. Work is usually standard-rated for VAT unless the building qualifies for a relief, which we confirm on the quote.
