Blown mineral wool insulation for Rhosllannerchrugog properties
If your property is in Rhosllannerchrugog or the LL14 district or nearby Wrexham, Buckley and Hawarden, it is within our Clwyd coverage. It is about 4 miles south-west of Wrexham.
Rhosllannerchrugog properties with rendered or painted walls get a closer look at the outer finish, because cracked render can let rain behind it. Where a Rhosllannerchrugog property has an extension or a conservatory, we check how the old and new walls meet, because that junction is often missed.
Exposure matters for every cavity wall. 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.
For regulations, 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.

When is it not the right choice?
Very narrow or uneven cavities, walls with lots of mortar snots and debris, and some very exposed elevations can be better suited to bonded bead, which flows around obstructions and is certified for a wider range of exposure zones in some systems. The survey says which and why.
