Homes and walls in Cwmbran
Surveys in Cwmbran also cover the surrounding NP44 district and towns such as Pontypool and Risca. It's roughly 5 miles from Cwmbran to Newport (Gwent), the largest town in 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
Householder rules in Wales are similar to England's: in Cwmbran, a similar-looking finish on a house is often permitted, but conservation areas, flats and listed buildings need permission or consent.
Welsh Building Regulations expect walls to be upgraded when a substantial area is renewed, and building control signs the work off.

Cwmbran: questions
Do you cover Cwmbran?
Yes — we survey and quote in Cwmbran (NP44) and nearby Pontypool, Risca and Newport (Gwent).
How much does external wall insulation cost in Cwmbran?
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 Cwmbran?
For homes in Cwmbran, 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.
