Frequently asked questions
Last reviewed: October 2026
What types of home insulation do you install?
We install the main types of home insulation used in Scottish properties, including loft, cavity wall, internal wall, external wall and underfloor insulation. Each type slows the rate heat escapes from your home, keeping rooms warmer for longer. The right choice depends on how your home is built, its age and where heat is currently lost.
Is insulation worth it in Scotland's climate?
Yes, insulation is one of the most worthwhile upgrades for Scottish homes because long, cold and windy winters mean heating runs for much of the year. Keeping heat inside helps rooms feel more comfortable and reduces how hard your heating works. It also prepares your home well for a future heat pump or other low-carbon heating.
How does the free insulation survey work?
Your free, no-obligation insulation survey checks how your home is built and where it loses heat. We look at the loft, walls, floors and ventilation, and note any damp or access issues that affect the work. You then receive clear recommendations and a written quote, with the reasons behind each suggested measure explained in plain terms.
What happens on insulation installation day?
On installation day, the team protects floors and furnishings, prepares the work area and fits the agreed insulation. Loft and cavity jobs are usually straightforward, while internal or external wall insulation takes longer and is planned in stages. Ventilation is checked throughout, and the team tidies up and walks you through the finished work before leaving.
Is finance available for insulation work?
Yes. Loans available, subject to status, so you can spread the cost of insulation rather than paying it all at once. Your adviser explains the funding and finance options you may qualify for during your free survey. Any finance is arranged through authorised lenders, and you are under no obligation to proceed with the work.
