Homes and walls in Risca
We cover Risca and nearby Newport (Gwent), Cwmbran and Caerphilly. Risca sits around 5 miles from Newport (Gwent).
South Wales has long runs of solid-wall valley terraces, Victorian and Edwardian town housing and post-war council estates.
Exposure to wind-driven rain varies across Gwent: sheltered town streets fare better than walls on high ground or facing the prevailing weather, and the render, beads and cill details are chosen with that in mind.

Approvals in Wales
We check Risca addresses for conservation areas and listing before quoting, because Welsh permitted development rules don't cover every external change.
In Wales, insulating or re-rendering more than half of a wall's area is treated as renovating a thermal element under Approved Document L (Wales), so building control is involved before work starts.

Risca: questions
Do you cover Risca?
Yes — we survey and quote in Risca (NP11) and nearby Newport (Gwent), Cwmbran and Caerphilly.
How much does external wall insulation cost in Risca?
Our guide is £105–£170 per m² depending on the system, plus scaffolding — roughly £10,200–£17,700 for a typical three-bed semi with EPS and silicone render. Installing insulation in a home is zero-rated for VAT until 31 March 2027, so that's the total. A free survey fixes the price.
Do I need planning permission in Risca?
For homes in Risca, the local planning authority decides any borderline cases; changing a brick house to render, or work on flats, usually needs an application in Wales.
Is VAT charged on wall insulation?
Installing wall insulation in homes is zero-rated until 31 March 2027, then 5%, so our insulation prices are totals. Render-only work and repairs carry VAT at 20%, and our prices for them include it.
