Existing insulation and guarantee check for Newtown properties

Newtown is among the towns we cover in Powys, alongside Welshpool and Llandrindod Wells. Newtown is one of the main towns we cover in Powys.

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

Wind-driven rain is the first thing the surveyor weighs up. Parts of Powys 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, if cavity wall insulation follows in Newtown, filling a cavity is notifiable work under the Building Regulations as they apply in Wales, usually self-certified through a competent person scheme.
