Rules for uPVC windows in Scotland
The rules for replacement windows in Scotland are set by the Building Standards Technical Handbook (Domestic), section 6: 1.6 W/m²K. Replacing a window or door, frame and all, does not need a building warrant, but the work must still meet the building standards.
Before ordering: Since May 2024, replacement windows on houses are widely permitted development, including in many conservation areas, with front elevations expected to match the existing closely; your council tells you if prior notification applies. Flats outside conservation areas generally need permission only if the opening size changes. Listed buildings need listed building consent.
How it works
We start with a survey, not a sales pitch: measurements, the structure above any bays, trickle-vent needs and escape windows. The quote that follows fixes the price, and anything unexpected on the day is agreed with you first.
- Every opening measured, including escape and vent needs
- Frames rated for the weight of triple glass
- Old windows removed and taken away
- Each opening closed up the same day
Questions from Vale of Leven
Will triple glazed uPVC windows look bulky?
The frames look much the same as good double glazed uPVC. The glass unit is thicker, but that sits inside the frame, so from outside the difference is hard to spot.
Do I need trickle vents?
In England and Wales, if your old windows had trickle vents, the new ones must have vents at least as big, and if they did not, the room must be no less ventilated than before. Scotland and Northern Ireland also require that replacement windows do not make ventilation worse. We size vents on the survey.
Do I need permission for triple glazed uPVC windows in Vale of Leven?
In Scotland, replacement windows on houses are widely permitted development since May 2024, with front elevations expected to match closely; listed buildings need consent. Check whether your street is in a conservation area or covered by an Article 4 direction before changing the style.
