Commercial cavity wall insulation for Swansea properties
Swansea sits in West Glamorgan. We work across the SA1 district, including nearby Briton Ferry, Gorseinon and Neath.
Per-address photo records for Swansea properties make compliance files and EPC updates straightforward. Work on Swansea 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 West Glamorgan 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 compliance, in Swansea filling a cavity is notifiable work under the Building Regulations as they apply in Wales, usually self-certified through a competent person scheme.
Funding in Wales
In Wales, Warm Homes Nest offers free improvements to eligible low-income households, and ECO4 runs to 31 December 2026.

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.
