Cavity wall insulation for flats for Rhosllannerchrugog properties
Rhosllannerchrugog sits in Clwyd, around 4 miles south-west of Wrexham. We work across the LL14 district, including nearby Wrexham, Buckley and Hawarden.
Work on Rhosllannerchrugog rented homes and blocks is booked around tenants and residents, with access arranged through your agent if you prefer. Blocks of flats in Rhosllannerchrugog 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 Clwyd 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 compliance, in Rhosllannerchrugog 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.
