Rules 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
Are timber windows warmer than uPVC?
They can be. Timber insulates well, and a deep timber frame with triple glass reaches whole-window U-values around 0.8 to 1.1, similar to good uPVC.
How long do timber windows take?
Usually 6 to 10 weeks from survey because each window is made to order and finished in the factory. We never quote less than 5 weeks for timber.
Can I get triple glazed timber sash windows?
Yes, though not every sash design can take a full-thickness triple unit. Where the box and sash sizes limit the unit, we tell you the U-value you will actually get.
Do you cover all of the Forth Valley?
We arrange surveys and fitting across the Forth Valley.
Do I need permission for triple glazed timber windows in Scotland?
In Scotland, replacement windows on houses are widely permitted development since May 2024, with front elevations expected to match closely; listed buildings need consent.
