Homes and walls in Carmarthen
As well as Carmarthen itself, we quote in Llanelli, Ammanford and Gorseinon. Carmarthen sits around 14 miles from Llanelli.
West Wales has a high share of older solid-walled and stone homes, many in exposed coastal or rural settings.
Parts of Dyfed fall in the higher wind-driven rain exposure bands, especially coastal and upland sites, so render specification, movement joints and detailing at cills, verges and the base of the wall matter more than usual.

Approvals in Wales
We check Carmarthen addresses for conservation areas and listing before quoting, because Welsh permitted development rules don't cover every external change.
Welsh Building Regulations expect walls to be upgraded when a substantial area is renewed, and building control signs the work off.

Carmarthen: questions
Do you cover Carmarthen?
Yes — we survey and quote in Carmarthen (SA31) and nearby Llanelli, Ammanford and Gorseinon.
How much does external wall insulation cost in Carmarthen?
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 Carmarthen?
For homes in Carmarthen, 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.
