Quick Answers About Scottish Windows

How much do new windows cost in Scotland?

uPVC windows: £300-800 per window. Aluminium: £800-1,500. Prices vary by style, size, and whether scaffolding is needed for tenements.

Do I need planning permission?

Most replacements dont need permission if similar in appearance. Conservation areas and listed buildings have stricter rules - always check first.

What energy rating should I look for?

We recommend minimum A rating for Scottish homes. A+ rated double glazing can improve your EPC by 1-2 bands and reduce bills by up to £200/year.

How long does installation take?

Single window: 2-3 hours. Full house (6-8 windows): 1-2 days. Tenement with scaffolding: 2-4 days. Most installers start within 4-6 weeks.
