What the job covers
- Internal insulation suits single rooms or where the outside can't change
- External insulation keeps room sizes and treats cold bridges well
- Breathable options for stone and lime-mortared walls
- Solid walls can lose heat roughly twice as fast as an insulated cavity wall
- Both can be done in stages, elevation by elevation or room by room
Before we quote in Dumfries and Galloway
South West Scotland has stone and harled houses, coastal towns and post-war council housing.
Parts of Dumfries and Galloway 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.
On solid-walled houses in Dumfries and Galloway, the gable or the most weather-exposed wall is often the place to start.

Permissions in Scotland
In Scotland, householder permitted development rights are set by the Scottish GPDO and are narrower for external wall changes; insulating flats or tenements, changing the appearance of a house noticeably, or working in a conservation area usually needs planning permission. Listed buildings need listed building consent. Ask your council's planning team before committing.
Work that alters an external wall's construction is covered by the building standards system; many over-cladding projects need a building warrant from the council's building standards team, and Section 6 (Energy) of the Technical Handbooks sets insulation benchmarks.
External or internal — which is better?
External insulation keeps the wall warm, reduces cold bridging at floors and party walls, renews the outside, and doesn't shrink rooms — but it changes the look and needs scaffolding. Internal insulation keeps the façade unchanged and can be done room by room, but loses 50–100mm of floor space per wall and needs careful detailing to avoid condensation at joists and corners.

Solid wall insulation in Dumfries and Galloway: questions
Is solid wall insulation worth it?
For many solid-walled homes it's one of the biggest single improvements to comfort, because the walls are often the largest heat-loss area. Savings depend on the home and heating, so we don't promise a figure.
Can I get a grant for solid wall insulation?
Some schemes cover it for eligible households — for example ECO4 until 31 December 2026, Home Energy Scotland's grant and loan, Wales' Warm Homes Nest and NI's Affordable Warmth Scheme. Each has its own eligibility and installer rules; see our grants guide.
Can I do one wall at a time?
Yes. Many owners start with the coldest or most exposed elevation, often a gable end.
Do you cover all of Dumfries and Galloway?
Yes. We survey and quote solid wall insulation across Dumfries and Galloway, including Dumfries, Stranraer, Annan.
Do I need planning permission in Scotland?
