Homes and walls 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.
Two-tone schemes, such as a darker plinth or entrance surround, are an option on houses in Wiltshire.

England: planning and regulations
For houses, external wall insulation and render are often permitted development where the finish looks similar to the existing walls. Planning permission is usually needed in conservation areas, National Parks, National Landscapes, the Broads and World Heritage Sites (where cladding a house in stone, artificial stone, pebble dash, render, timber, plastic or tiles isn't permitted development), for flats and maisonettes, for commercial buildings, under an Article 4 direction, or where the look changes noticeably. Listed buildings need listed building consent.
Renovating more than half of a wall's area — insulating it, or stripping and re-rendering it — or more than a quarter of the building's whole external envelope brings in the energy requirements of Part L, so building control needs to be involved and the wall should reach about 0.30 W/m²K where that's technically, functionally and economically feasible.
Can I choose two colours?
Yes. Many owners pick a main colour with a contrasting plinth, entrance surround or bay. Feature bands and recessed details can be formed in the insulation before rendering.

Insulated render in Wiltshire: questions
Will my house look different?
Yes, if it was brick or pebble dash. If you want to keep a brick look, a brick-slip finish over the insulation is an option.
Does insulated render need painting?
Through-coloured silicone and acrylic renders don't need painting. Mineral renders are usually painted with a compatible masonry paint.
Can insulated render be applied in winter?
Only in suitable weather — typically above 5°C and rising, with no frost or rain during curing. Winter programmes allow for lost days.
Do you cover all of Wiltshire?
Yes. We survey and quote insulated render across Wiltshire, including Swindon, Salisbury, Trowbridge, Chippenham.
