Existing insulation and guarantee check for Neath properties

Neath is among the towns we cover in West Glamorgan, alongside Briton Ferry, Swansea and Gorseinon. It is around 7 miles north-east of Swansea.

Buyers and sellers in Neath often book this check when a survey report or EPC raises questions about the walls. The written result for your Neath property is plain English: what we found, what it means and what, if anything, to do next.

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.

In terms of approvals, if cavity wall insulation follows in Neath, filling a cavity is notifiable work under the Building Regulations as they apply in Wales, usually self-certified through a competent person scheme.

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.
