What we look for in Scottish Borders
The Scottish Borders have stone-built towns and villages, rural cottages and some post-war estates.
Exposure to wind-driven rain varies across Scottish Borders: 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 Scotland
Internal insulation rarely needs planning permission, but listed buildings need listed building consent for internal changes that affect their character.
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.
What are the risks with internal insulation?
Insulating inside makes the masonry colder, so moisture risk rises. Weak points are where floor joists bear into the wall, window reveals and corners. A condensation risk check for the build-up, a continuous vapour control layer where specified, and returning insulation into reveals deal with most of it.

Internal wall insulation in Scottish Borders: questions
Is internal insulation cheaper than external?
Per m² usually yes, but the cost of moving fittings and redecorating narrows the gap on whole-house jobs.
How much room space will I lose?
Usually 50–100mm on each insulated wall, depending on the system.
Can I stay in the house?
Yes, but each room is out of use while it's worked on, typically 3–5 days.
Do you cover all of Scottish Borders?
Yes. We survey and quote internal wall insulation across Scottish Borders, including Hawick, Galashiels, Peebles, Kelso.
Do I need planning permission 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. We check your address before quoting.
