Before we quote in Ayrshire
South West Scotland has stone and harled houses, coastal towns and post-war council housing.
Parts of Ayrshire 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.
Where a property in Ayrshire is in a conservation area or the front elevation must stay unchanged, internal insulation is often the practical route.

Planning and building control 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 Ayrshire: questions
What happens to my radiators and sockets?
They're taken off and refitted on the new wall face. Electrical work is done by a qualified electrician.
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.
Do you cover all of Ayrshire?
Yes. We survey and quote internal wall insulation across Ayrshire, including Kilmarnock, Ayr, Irvine.
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.
