Homes and walls in Trowbridge
We also cover Bath and Frome, close to Trowbridge. It's roughly 25 miles from Trowbridge to Swindon, the largest town in Wiltshire.
The South West has many stone and solid-walled cottages, exposed coastal properties and a share of post-war system-built houses, including types such as the Cornish Unit.
Exposure to wind-driven rain varies across Wiltshire: 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 England
Before quoting in Trowbridge, we check whether the property is in a conservation area, under an Article 4 direction or listed, because that decides whether changing the outside needs planning permission.
If the work covers more than half of a wall, or a quarter of the building's whole envelope, it counts as renovating a thermal element, with a target of about 0.30 W/m²K where feasible.

Yes — we survey and quote in Trowbridge (BA14) and nearby Bath, Frome and Chippenham.
How much does external wall insulation cost in Trowbridge?
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 Trowbridge?
For a house in Trowbridge, external insulation or render is often permitted development if it looks similar to the existing walls; conservation areas, flats, commercial buildings and listed buildings need permission or consent, so we check your address first.
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.
