Cavity wall insulation for flats for Risca properties
Risca is among the towns we cover in Gwent, alongside Newport, Cwmbran and Caerphilly. It is roughly 4 miles west of Newport.
For landlords and managing agents in Risca, we survey in batches and return a result sheet and fixed price per address. Blocks of flats in Risca are surveyed as a whole, because the cavity runs across every flat in the building.
Before any material is chosen, exposure is checked. Parts of Gwent 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, in Risca 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.
