Cavity wall insulation for flats for Aberystwyth properties
If your property is in Aberystwyth or the SY23 district or nearby Carmarthen and Ammanford, it is within our Dyfed coverage. It is around 38 miles north of Carmarthen.
Work on Aberystwyth rented homes and blocks is booked around tenants and residents, with access arranged through your agent if you prefer. For landlords and managing agents in Aberystwyth, we survey in batches and return a result sheet and fixed price per address.
Every elevation is judged on its own exposure. 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 Aberystwyth 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
In Wales, Warm Homes Nest offers free improvements to eligible low-income households, and ECO4 runs to 31 December 2026.
Sources: Welsh Government: warmer and more energy efficient homes (July 2026); GOV.UK: extending the ECO4 end date, government response.
Fire and height
For blocks, the material must suit the building's height and use. Non-combustible mineral wool is the usual choice; we confirm the system and its certificate limits in writing.
