Cavity wall insulation for landlords for Carmarthen properties
Carmarthen is among the towns we cover in Dyfed, alongside Llanelli and Ammanford. Carmarthen is one of the main towns we cover in Dyfed.
Blocks of flats in Carmarthen are surveyed as a whole, because the cavity runs across every flat in the building. Per-address photo records for Carmarthen properties make compliance files and EPC updates straightforward.
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.
On the rules side, in Carmarthen 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
