Existing insulation and guarantee check across West Glamorgan

We cover 4 towns in West Glamorgan: Swansea, Neath, Briton Ferry and Gorseinon.

Every elevation is judged on its own exposure. 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.

A survey in West Glamorgan gives you facts before anyone drills: what the wall is, what is in the cavity and whether it is sound. Buyers and sellers in West Glamorgan often book this check when a survey report or EPC raises questions about the walls.

Building Regulations in Wales

In Wales, filling an existing cavity is also notifiable building work under the Building Regulations as they apply in Wales. A registered installer normally self-certifies it through a competent person scheme; otherwise a building notice goes to your council's building control before work starts. Welsh rules can differ from England's, so the notification route is confirmed in writing on your quote.

Tracing a guarantee

Many cavity fills carry a 25-year guarantee from the Cavity Insulation Guarantee Agency (CIGA). CIGA can confirm whether a property is covered and can issue a duplicate guarantee for a fee; at the time of writing that fee is £60 including VAT, and proof of ownership is required.
