Rules in Scotland
In Scotland, replacement external doors must meet 1.6 W/m²K. Replacing a door or window, frame and all, does not need a building warrant, but the work must still meet the building standards.
Before ordering: A replacement door on a house that looks similar to the existing one is generally permitted development; check with your council for flats and conservation areas, and listed buildings need listed building consent.
How it works
After the free survey you get a written quote naming the frame system, the glass build-up and the whole-window U-value for every item. Windows are made to order, then fitted, sealed and made good, one opening at a time.
- Guide prices published, not hidden
- No pressure: the quote is yours to keep

In Scotland, a replacement door on a house that looks similar is generally permitted development; check with your council for flats and conservation areas, and listed buildings need consent.
