Cavity wall insulation for landlords across Dyfed

We cover 6 towns in Dyfed, including Llanelli, Ammanford, Carmarthen, Aberystwyth, Haverfordwest and more.

Local weather affects which walls can be filled. Parts of Dyfed 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.

Blocks of flats in Dyfed are surveyed as a whole, because the cavity runs across every flat in the building. For landlords and managing agents in Dyfed, we survey in batches and return a result sheet and fixed price per address.

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.
